Are manufactured diamonds really indistinguishable from natural diamonds? And do you have an opinion on whether manufactured diamonds will make natural diamonds obsolete?

Physically? Chemically? Yup, they are in every way, shape and form diamonds. Back in the old days, when they made synthetic diamonds via a process called chemical vapor deposition, it was sometimes possible to distinguish them visually under magnification. Nowadays, the technology has improved to the point where I, a graduate gemologist, cannot visually distinguish between them with any of the tools I have available. Advanced laboratory testing and very expensive equipment is required.

They've certainly caused a shake-up in the diamond industry, with the price of LG crashing tremendously the last two years and taking the price of earth-mined with it. Long term...? Obsolescence is a spectrum. If the earth-mined diamond industry tanks, so will the supply, prices will rise... it'll be interesting to see. I think earth-mined will still have some cachet once things level off. We've had synthetic colored stones for 150 years at this point, and people still want Columbian emeralds.

Now, what I think is SUPER COOL about LG diamonds is that because the material is so cheap, comparatively speaking, they're doing REALLY AWESOME THINGS with them. Like this ring, carved entirely out of a lab grown-diamond:

Or this super unique flame-cut diamond:

People are experimenting with weird shapes, odd colors, oddball cuts and experimental designs, which I think is SUPER COOL. Diamonds are beautiful (I'm aware of the industry and synthetic demand and all that jazz. The fact remains, they are beautiful stones. Look at a well-cut diamond in good lighting. They are stunning and magical) and I'm really excited to see what they'll come up with next, design-wise. I wear lab-grown diamonds. So does my husband. I like 'em.

How are pink lab-grown diamonds graded for color and clarity?

The Travels of a Lab-Grown Pink Diamond

In order to better understand the grading procedure, let's examine the path a pink lab-grown diamond takes from formation to certification:

The diamond is first produced in a state-of-the-art laboratory using either Chemical Vapor Deposition (CVD) or High Pressure High Temperature (HPHT) methods.

Certain trace elements, like boron, can be added during the growth phase to produce the pink color, or post-growth treatments like heat and radiation can do the same.

Pink diamonds are rated using an elaborate color system, in contrast to colorless diamonds.

Lunar ice deposits are widespread

Deposits of ice in lunar dust and rock (regolith) are more extensive than previously thought, according to a new analysis of data from NASA’s LRO (Lunar Reconnaissance Orbiter) mission. Ice would be a valuable resource for future lunar expeditions. Water could be used for radiation protection and supporting human explorers, or broken into its hydrogen and oxygen components to make rocket fuel, energy, and breathable air.

Prior studies found signs of ice in the larger permanently shadowed regions (PSRs) near the lunar South Pole, including areas within Cabeus, Haworth, Shoemaker and Faustini craters. In the new work, “We find that there is widespread evidence of water ice within PSRs outside the South Pole, towards at least 77 degrees south latitude,” said Dr. Timothy P. McClanahan of NASA’s Goddard Space Flight Center in Greenbelt, Maryland, and lead author of a paper on this research published October 2 in the Planetary Science Journal.

The study further aids lunar mission planners by providing maps and identifying the surface characteristics that show where ice is likely and less likely to be found, with evidence for why that should be. “Our model and analysis show that greatest ice concentrations are expected to occur near the PSRs’ coldest locations below 75 Kelvin (-198°C or -325°F) and near the base of the PSRs’ poleward-facing slopes,” said McClanahan.

“We can’t accurately determine the volume of the PSRs’ ice deposits or identify if they might be buried under a dry layer of regolith. However, we expect that for each surface 1.2 square yards (square meter) residing over these deposits there should be at least about five more quarts (five more liters) of ice within the surface top 3.3 feet (meter), as compared to their surrounding areas,” said McClanahan. The study also mapped where fewer, smaller, or lower-concentration ice deposits would be expected, occurring primarily towards warmer, periodically illuminated areas.

Ice could become implanted in lunar regolith through comet and meteor impacts, released as vapor (gas) from the lunar interior, or be formed by chemical reactions between hydrogen in the solar wind and oxygen in the regolith. PSRs typically occur in topographic depressions near the lunar poles. Because of the low Sun angle, these areas haven’t seen sunlight for up to billions of years, so are perpetually in extreme cold. Ice molecules are thought to be repeatedly dislodged from the regolith by meteorites, space radiation, or sunlight and travel across the lunar surface until they land in a PSR where they are entrapped by extreme cold. The PSR’s continuously cold surfaces can preserve ice molecules near the surface for perhaps billions of years, where they may accumulate into a deposit that is rich enough to mine. Ice is thought to be quickly lost on surfaces that are exposed to direct sunlight, which precludes their accumulations.  

The team used LRO’s Lunar Exploration Neutron Detector (LEND) instrument to detect signs of ice deposits by measuring moderate-energy, “epithermal” neutrons. Specifically, the team used LEND’s Collimated Sensor for Epithermal Neutrons (CSETN) that has a fixed 18.6-mile (30-kilometer) diameter field-of-view. Neutrons are created by high-energy galactic cosmic rays that come from powerful deep-space events such as exploding stars, that impact the lunar surface, break up regolith atoms, and scatter subatomic particles called neutrons. The neutrons, which can originate from up to about a 3.3-foot (meter’s) depth, ping-pong their way through the regolith, running into other atoms. Some get directed into space, where they can be detected by LEND.  Since hydrogen is about the same mass as a neutron, a collision with hydrogen causes the neutron to lose relatively more energy than a collision with most common regolith elements. So, where hydrogen is present in regolith, its concentration creates a corresponding reduction in the observed number of moderate-energy neutrons.

“We hypothesized that if all PSRs have the same hydrogen concentration, then CSETN should proportionally detect their hydrogen concentrations as a function of their areas. So, more hydrogen should be observed towards the larger-area PSRs,” said McClanahan.

The model was developed from a theoretical study that demonstrated how similarly hydrogen-enhanced PSRs would be detected by CSETNs fixed-area field-of-view. The correlation was demonstrated using the neutron emissions from 502 PSRs with areas ranging from 1.5 square miles (4 km2) to 417 square miles (1079 km2) that contrasted against their surrounding less hydrogen-enhanced areas. The correlation was expectedly weak for the small PSRs but increased towards the larger-area PSRs.

Research team develops a more durable coating against ice

Ice-repellent coatings have been around for some time, but until now they have been very sensitive and detach quite quickly from the surfaces they are meant to protect. A research team led by Anna Maria Coclite and Gabriel Hernández Rodríguez from the Institute of Solid State Physics at Graz University of Technology (TU Graz) has now succeeded in remedying this shortcoming. They have developed a highly ice-repellent coating that adheres to a wide variety of materials and is very resistant to abrasion. The team's paper is published in the journal ACS Applied Materials & Interfaces. The researchers achieved this progress by using a manufacturing technology called initiated chemical vapor deposition (iCVD). This makes it possible for a strongly adhesive primer material to gradually transition into the ice-repellent compound.

how safe are weed vapes compared to like regular vapes? I've recently heard vapes are like horrible for you cus you're just smoking a shit ton of chemicals but does that depends on what's being smoked?....since you said the weed is just being heated up is there less chemical intake overall or just less combustion byproduct like you said before (sorry if this makes like no sense I'm not familiar with this stuff at all or how it works lol but I also had a really bad experience with edibles and have bad lungs so I just wanted to know a bit more)

Hey sorry for responding so late I had gotten most of this post done after you first sent it but I ran out of energy and got too perfectionistic. Anyways here it is:

Excellent question! The first formal modern e-liquid vape was only released in 2003, though various attempts had been made earlier, which means we are still researching the long-term effects they have on health. When the average person says "vape", they almost exclusively mean "e-liquid vape".

Currently, what we can see about e-liquid vapes: They're not very good. They do reduce some smoking risks (no tar) but introduce other risks, and have a reputation of being safer and a potential smoking cessation aid while a reality of unregulated and poorly sourced ingredients which can cause acute and lasting lung damage.

Dry herb vaping, which is what I recommend, is much more straightforward, but only recently popularized and thus still needing more research.

At the risk of being a square: Any time you intentionally inhale something other than air, you're introducing more risk than if you simply never smoked or vaped anything. But like don't let that stop you, we take on risk all the time, that's what harm reduction's all about babey

Dry Vapes are Not Vapes

A vape or e-cigarette is a device that heats and vaporizes a liquid carrier with a suspension of the psychoactive chemical, either nicotine or THC. These are what people think of when they think of vapes, and these are generally the most problematic for having untested and unregulated chemicals while being touted as healthier.

A dry vape/dry herb vaporizer is the method I recommend, which heats the plant material (or concentrate like wax--I haven't done this myself personally) and evaporates the cannabinoids and terpenes without combustion. It's basically like baking your weed in a tiny oven.

This method was popularized most recently in 1993 with Eagle Bill's Shake and Vape, though apparently the principle of boiling vapor has existed since ancient times.

General Smoking Health Risks

Tobacco and weed both produce "tar" when burned--a catch-all for a variety of chemicals, many of which are carcinogenic, produced during combustion. The tar isn't made from the THC or the nicotine, but from the plant matter itself and its additives. If you burn plant matter and inhale the smoke, you inhale a certain number of toxic and carcinogenic chemicals.

There is some conflict on if smoking weed causes cancer. It certainly doesn't carry the same correlation as tobacco, but the reasons are unknown. We don't have long-term studies verifying a connection between the two. Very preliminary lab tests suggest that THC and CBD have antitumor effects, but it'll be a while before we can figure out the deal. There is still risk!!!

Regardless, the deposition of tar in lungs is an irritant and increases risks of things like bronchitis. For someone with asthma or weak lungs, smoking of any kind causes problems.

E-Cigarettes, or e-liquid vapes

E-cigarettes were manufactured to counter tobacco cigs starting in 2003. An e-cig heats a liquid with a suspension of nicotine, atomizing it into droplets of vapor that are then inhaled.

The liquid is usually propylene glycol or glycerol with other additives like flavorants. It seems like propylene glycol and glycerol have been safe for ingestion as a food additive, but being atomized in an inhaled form is pretty new and the effects aren't well-known.

The major issue is that we don't have a standardized and proven-effective vape juice formula. E-liquid is poorly regulated and many samples contain entirely unidentified substances.

This is the major cause for concern.

THC vape liquids have similar issues, including being cut with Vitamin E acetate, which was correlated with a string of vaping-related lung disease, though not fully confirmed to be the culprit.

Hopefully this delineates why vaping, as in e-liquid vaping, is problematic, and why dry vape is comparatively safer.

Why dry herb vape?

The boiling of the material introduces fewer (but not 0) unknown or undesired chemicals into the airstream. You're primarily getting the cannabinoids.

On a user experience level: It's quite weed-efficient, the weed tastes better w/o the smoke, it produces less smell, the vapor is less harsh on the lungs (you can and will still cough if you inhale too much tho), not much less portable than a joint

You can get a bong adapter and get megahigh still (I do have a bong but I don't like getting that fucked up)

Some vapes can heat concentrates, wax, etc. for potent highs (I haven't done this. But you can. Research yourself)

The already vaped bud (AVB) can be saved and reused for edibles, extracts, and concentrates; it's gonna be stripped of a lot of the psychoactives already, but not all of them--obvs be mindful of dosing here

Downsides: You do have to recharge battery vapes and get over the learning curve of batteryless (I'm pretty shit at using mine). You also have to clean your equipment every once in a while which is nbd for me who likes cleaning but yknow it does require upkeep. Easier than cleaning a bong tho

So, could you dry vape tobacco?

You can, but you probably shouldn't. Nicotine itself is highly physically and psychologically addictive and classified as toxic, and while it isn't considered carcinogenic, it is potentially a tumor promoter.

Pretty much everyone I know who's on nic tells me they don't like it, they wish they could quit, and they would never want me or anyone else to start.

Last, some Dry Herb Vaporizer Tips

Controlling the temperature allows you to control which cannabinoids are released to a certain extent.

Hot vapor can still irritate your lungs. Keeping a relatively low temperature (Guides indicate the best range) and having a long enough vapor path that the vapor can cool will help you have a smoother inhale.

Do not use a vaporizer with cheap elements. Plastic near the heating element will cause by-products.

Contaminants and pesticides can be inhaled, source your material appropriately

Overheating can still cause combustion. You will smell, taste, and see smoke if this happens.

All the physical and psychological risks of weed are present--Take it easy, know your limits, don't vape or smoke when you're in an unstable state, etc.

Thanks for reading, I hope this helps you make informed decisions and potentially find a way of intaking weed that suits your needs :) If you have any more Qs I'll try to answer (IN FEWER WORDS)

Cutting Tools in Industry 4.0: Breaking through Performance Barriers

Table of Contents Charting the Evolution of Cutting Tools Responding to Process Challenges Conclusion: Productivity or Price Cutting tools are central to machining processes for making industrial machinery, watch components, and car and aircraft parts. Given this diverse applicability, they are in high demand and the subject of significant innovation. Comprising saws, reamers, drills, chasers, cutters, end mills, boring tools, honing tools, combination tools, and gear-cutting tools, the scope and quality of industrial cutting tools is a constant test for innovators. Accordingly, they have focused on improving tool durability, speed, and precision, with tool geometry and application-specific design also in focus.

Newer materials like cermet and polycrystalline diamonds (PCD) are stronger and more durable than the previously preferred High-Speed Steel (HSS) and Cemented Carbide. Creating the coatings that amplify tool strength leverages processes like Chemical Vapor Deposition (CVD) and Physical Vapor Deposition (PVD). Adopting Industry 4.0 methods such as Artificial Intelligence (AI) and the Internet of Things (IoT) has resulted in greater efficiency, cost reductions, and increased tool longevity. Additive manufacturing can usher in novelly designed tools. Equally, digitalization has enabled encompassing sustainability in tool design and manufacturing.

Charting the Evolution of Cutting Tools The development of carbide cutting tools, now spanning a century, offers vital clues to the expectations from newer technologies. The invention of cemented carbide was a significant milestone in the search for tool-grade materials with the ideal levels of hardness and toughness. Characteristics of tool-grade materials include versatile applicability – they can cut through most metals and metallic alloys and better withstand heat and wear. Some of the breakthrough high-performance materials used for making industrial cutting tools as an improvement on cemented carbide include:

Cermet, which is a sintered alloy of Titanium Carbide and Titanium Nitride Coated carbides, wherein the strength of the carbide cutting tool is augmented using a film of diamond, diamond-like carbon (DLC), or aluminum layered using CVD or PVD. Polycrystalline Cubic Boron Nitride (PCBN), whose advantages include extreme heat resistance and hardness The evolution of these materials is also a response to the application and the work material. For instance, PCD cutting tools are suitable for working on non-ferrous materials like high-silicon aluminum. The advent of carbon composites with laminated structures like Carbon Fiber Reinforced Polymer (CFRP) has also encouraged further research into tool materials. Developers have also investigated changing the tool geometry – for example, the shape and angle of the cutting edge – for milling or drilling into advanced materials precisely. Additive manufacturing, which involves fashioning 3D-printed cutting tool parts from metal powders, teases the possibility of imaginatively shaping cutting tools with greater complexity.

Responding to Process Challenges The wear and tear of cutting tools necessitates frequent repair or replacement. Tools with replaceable cutting tips, called indexable tools, help lower costs and simplify maintenance. The machining scale also matters; micro-drilling tools address reliability issues when machining small parts. On another front, metalworking fluids are invariably required to lower friction and preserve the tool but pose risks to workers’ health and safety. Altering tool composition or design has minimized the use of these fluids.

Metalworking fluids are invariably required to extend tool life

The heavy use and regular changing of cutting tools raise questions regarding their sustainable use. Using optimized materials that break down less easily reduces the tool replacement frequency. In this regard, AI-enabled sustainable manufacturing approaches like automating the selection of tooling materials, facilitating predictive maintenance, and leveraging sensors to detect tool damage can positively impact the entire cutting tool lifecycle from production to deployment and disposal or reuse. Improving the tools’ energy efficiency is also a step forward from a sustainability perspective.

Conclusion: Productivity or Price Despite the ever-growing demand and the continuous development of more productive and longer-lasting cutting tools, the market remains price-differentiated. Crucially, expenditure on cutting tools amounts to only 2-3% of the total production cost. Cutting tools manufacturers have a significant opportunity to evangelize high-tech cutting tools that more rapidly produce better-finished, higher-quality machine parts and yet do not massively increase tooling costs. The shift to custom-designed complex cutting tools can also push manufacturers to take a productivity-first stance when equipping their assembly lines.

Lab-Grown Diamonds and Their Role in Reducing the Carbon Footprint of the Jewelry Industry

In recent years, sustainability has become a central focus for consumers, and the jewelry industry is no exception. As people become more conscious of their environmental impact, many are turning to lab-grown diamonds as a greener alternative to traditional mined diamonds. Lab-grown diamonds not only offer a beautiful, ethical, and affordable option, but they also play a significant role in reducing the carbon footprint of the jewelry industry.

In this post, we will explore how lab-grown diamonds are contributing to a more sustainable future and why they are an essential part of reducing the environmental impact of the jewelry sector.

How Lab-Grown Diamonds Are Made

To understand the environmental benefits of lab-grown diamonds, it’s essential to first know how they are created. Unlike mined diamonds, which are formed over millions of years under extreme pressure and heat deep within the Earth, lab-grown diamonds are made using advanced technology in controlled environments. There are two primary methods for creating lab-grown diamonds: High Pressure High Temperature (HPHT) and Chemical Vapor Deposition (CVD).

High Pressure High Temperature (HPHT) simulates the natural conditions that form diamonds. Carbon is subjected to intense heat and pressure, resulting in the crystallization of diamonds. This process takes several weeks and results in diamonds that are virtually identical to their natural counterparts.

Chemical Vapor Deposition (CVD) involves breaking down a carbon-rich gas in a vacuum chamber, causing carbon atoms to bond and form diamonds over time. This method is highly controlled, allowing for a variety of diamond shapes and sizes.

Both methods result in diamonds that are chemically and physically identical to mined diamonds but are produced in a much more sustainable way, without the need for mining or the associated environmental destruction.

The Carbon Footprint of Traditional Diamond Mining

Diamond mining has long been associated with high carbon emissions. The process of extracting diamonds from the earth requires large-scale mining operations, which use heavy machinery and energy-intensive methods to dig deep into the ground. The carbon emissions generated by these mining activities contribute significantly to the industry’s overall carbon footprint.

Additionally, the transportation of diamonds from the mining site to the market involves further emissions, as well as a significant amount of energy used in refining and cutting the diamonds. As a result, the carbon footprint of a mined diamond is considerable, with estimates suggesting that the production of a single carat of diamond can generate up to 500 to 600 kilograms of CO2 emissions.

How Lab-Grown Diamonds Help Reduce the Carbon Footprint

Lab-grown diamonds offer a sustainable alternative by significantly reducing the carbon emissions associated with diamond production. Here’s how:

Lower Energy ConsumptionThe production of lab-grown diamonds requires far less energy than traditional diamond mining. Mining is an energy-intensive process that involves extracting earth, crushing rocks, and processing raw materials. In contrast, lab-grown diamonds are created in controlled lab environments where energy use is optimized, and the entire process requires less power overall.

Reduced Greenhouse Gas EmissionsAccording to studies, lab-grown diamonds can reduce carbon emissions by up to 99% when compared to their mined counterparts. This dramatic reduction is achieved by eliminating the need for large-scale mining operations, which are responsible for a significant portion of the industry’s carbon emissions.

Sustainable Energy SourcesMany lab-grown diamond manufacturers are also adopting sustainable energy sources such as solar and wind power to further minimize their environmental impact. By relying on renewable energy, these companies are making an even more significant contribution to reducing their carbon footprint.

Efficient Production MethodsThe controlled environment used in the creation of lab-grown diamonds allows for greater efficiency in production. With precise control over the process, manufacturers can minimize waste, reduce energy consumption, and use fewer resources overall.

The Bigger Picture: Lab-Grown Diamonds and Climate Change

As the global conversation around climate change intensifies, every industry is being called to do its part in reducing its environmental impact. The jewelry industry, known for its beauty and luxury, is no exception. Lab-grown diamonds are leading the charge in helping to reduce the carbon footprint of the sector, providing an option that not only satisfies the consumer’s desire for beautiful diamonds but also aligns with their values of sustainability.

By choosing lab-grown diamonds, consumers can contribute to the fight against climate change by supporting an industry that prioritizes environmental stewardship. The reduction in carbon emissions alone makes a huge difference, and as demand for lab-grown diamonds continues to grow, the industry as a whole can become a powerful force for positive environmental change.

A Greener Future with Lab-Grown Diamonds

Lab-grown diamonds are more than just a trend—they represent the future of the jewelry industry. By offering an environmentally friendly alternative to mined diamonds, lab-grown diamonds help to reduce carbon emissions, conserve natural resources, and promote ethical practices.

As we look to a greener, more sustainable future, it’s clear that lab-grown diamonds will play an integral role in shaping the future of luxury. Whether you’re purchasing an engagement ring, an anniversary gift, or simply indulging in a beautiful piece of jewelry, choosing lab-grown diamonds is a conscious decision that aligns with values of sustainability and environmental responsibility.
