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)

Unlike natural diamonds, which are often mined under harsh conditions and may contribute to environmental damage and human rights abuses, lab diamonds are produced in controlled environments with minimal impact on the planet. This makes them an eco-friendly choice for conscientious consumers.

Conflict-Free: Lab diamonds are guaranteed to be conflict-free, meaning they are not associated with the financing of armed conflicts or human rights abuses, as some natural diamonds have been in the past. This assurance gives consumers peace of mind knowing that their purchase supports responsible and ethical practices.

Quality and Purity: Lab diamonds are identical in terms of their chemical composition, crystal structure, and optical properties to natural diamonds. They exhibit the same brilliance, fire, and durability as natural diamonds, making them a high-quality alternative at a lower price point.

Variety of Options: Lab-created diamonds offer a wide range of options in terms of size, shape, color, and clarity. Whether you're looking for a classic round brilliant cut or a unique fancy colored diamond, lab diamonds provide a variety of choices to suit every taste and preference.

Affordability: One of the most significant advantages of lab-created diamonds is their affordability compared to natural diamonds. On average, lab diamonds are priced at around 20-40% less than their natural counterparts of comparable quality. This cost savings allows consumers to purchase larger or higher-quality diamonds for the same budget, making lab diamonds an attractive option for those looking to maximize value without compromising on quality.

In conclusion, lab-created diamonds offer a compelling alternative to natural diamonds, providing ethical sourcing, superior quality, and affordability. With their sustainable production methods and indistinguishable beauty, lab diamonds are becoming increasingly popular among environmentally-conscious and budget-conscious consumers alike.

Lab Grown Diamonds Vs. Mined Diamonds: What You Should Know

Are lab diamonds real diamonds? YES! Are lab diamonds really worth something? YES!

There has been plenty of discussion regarding what a lab grown (additionally called lab-created) diamond is and if it’s a “actual” diamond. An wedding bands with emeralds: the perfect fusion of timeless elegance and the vibrant essence of your love.

Let’s dive into what units these stones apart (or doesn’t) from clearly-mined diamonds. Of course, it’s a non-public desire, but we don’t think lab grown diamonds are a fad, in reality, we think they’re here for the long haul.

What is a lab grown diamond?

The foremost difference between a lab grown diamond and a clearly-mined diamond is actually the way it is created. A mined diamond is fashioned obviously deep under the Earth’s crust wherein temperatures and pressures are very high. These diamonds can handiest be mined while uncommon volcanoes erupt and produce them near the surface. An emerald anniversary ring: a timeless treasure that symbolizes love as rare and vibrant as your bond.

We imitate that same manner in our lab using a High-Pressure High Temperature (HPHT) or Chemical Vapor Deposition (CVD) procedure. What begins as a diamond seed— a minuscule slice of a diamond— blossoms right into a big, rough diamond as carbon atoms grow round it. These stones are grown in licensed labs.

1. Are lab grown diamonds real diamonds?

Yes, they're actual diamonds. Lab grown and mined diamonds cannot be differentiated with the naked eye. They have the identical brilliance and grading gadget as a mined diamond. You can’t inform the distinction between lab grown diamonds and mined diamonds without specialized system, even in case you’re a professional gemologist! The nice way to tell the difference between lab grown diamonds and mined diamonds is to examine the grading record.

2. Do lab grown diamonds have flaws?

Both mined and lab grown diamonds are at the mercy of technology, and there may be no way to assure an excellent diamond. All diamonds will necessarily encompass one-of-a-kind amounts of flaws and inclusions, that's why they are graded and licensed.

Three. Are lab grown diamonds Certified?

A lab-grown diamond is graded and certified the usage of the identical system as a mined diamond. Just like our mined diamonds, our lab grown diamonds are sent to a gem lab that specializes in grading diamonds. Each diamond is graded using the 4C’s (cut, readability, shade, and carat). Both are held to the exact equal standards. (Learn extra approximately the 4Cs.) 

four. Why are lab grown diamonds much less costly?

Lab grown and mined diamonds have the identical costs on the subject of slicing, sprucing, and inspection. The difference in charge stems from engineering and mass amount produced. Embrace forever with an emerald rings gold band, a dazzling reflection of your enduring love.

5. Do lab grown diamonds hold cost?

Lab grown diamonds are produced in abundance; consequently, the following fee is unpredictable over the years.

6. Can you insure a lab grown diamond ring?

Lab grown diamonds may cost a little much less, however there is no difference in terms of insuring your precious piece of jewelry.

7. Is a Cubic Zirconia (CZ) and/or moissanite, similar to a lab grown diamond?

Absolutely now not. There is not anything greater notable or durable than a diamond. CZ's and moissanites are less durable and feature much less mild performance.

SHOULD I BUY MINED OR LAB GROWN DIAMOND?

There is not any wrong answer. The selection is entirely as much as you depending on which sort of diamond you opt for. 

You should purchase a lab grown diamond if:

You’re looking for a price range-pleasant choice (lab grown diamonds cost 30% much less, on common than their mined counterparts)

A lab grown diamond can constitute current love

Maybe you admire the latest advances in current generation 

You can buy a evidently-mined diamond if:

Having a mined diamond made obviously within the Earth is vital to you

Maybe you have a conventional method to like 

A mined diamond also can be a illustration of nature’s miracle surrounded by using mysterious origins

The backside line: Overall, lab grown stones share the equal physical and chemical properties as natural diamonds. Lab grown diamonds are real diamonds that closing forever but are an estimated 30% much less high-priced than mined diamonds. Overall, neither diamond is “better.” They are not in opposition with each other. What topics is the importance you put on your diamond and what it manner to you.
