How to tell if a diamond is moissanite?

Diamonds are symbols of love, commitment, and luxury, making them the top choice for engagement rings. However, moissanite, a popular diamond alternative, can sometimes be mistaken for a diamond due to its striking resemblance. If you're in the market for a sparkling gem, it’s essential to know how to distinguish between the two. This guide will provide you with key tips to ensure you're getting the diamond you want, rather than a moissanite stone, without compromising on beauty.

Understanding Diamonds and Moissanite

First, let’s define the two gems:

Diamonds are natural gemstones formed under immense pressure over billions of years. They're known for their brilliance, rarity, and enduring value.

Moissanite is a lab-created gemstone that looks incredibly similar to diamonds. Although it's not a diamond, moissanite is also durable and offers plenty of sparkle, though it has different properties.

While both gems are visually stunning, they are distinct in terms of chemical composition, brilliance, and overall appearance.

How to Tell If It's Moissanite

Brilliance Test: One of the key ways to tell a diamond from moissanite is through their brilliance. Moissanite tends to emit rainbow-like flashes when exposed to light, whereas diamonds reflect white light in a more subdued way. If the stone seems overly fiery, it could be moissanite.

Double Refraction: Moissanite exhibits a characteristic known as double refraction. This means that when you look closely through the stone, especially at the edges, you might see a double image of the facets. Diamonds, on the other hand, do not have this feature.

Hardness Test: Diamonds are the hardest known natural substance with a score of 10 on the Mohs scale of hardness, while moissanite comes in at a close 9.25. While both are scratch-resistant, diamonds still hold the upper hand in terms of overall durability.

Thermal Conductivity Test: A jeweler can test thermal conductivity using specialized tools. Diamonds disperse heat differently than moissanite. Some jewelers use this as an easy way to distinguish between the two.

Price Difference: Diamonds are significantly more expensive than moissanite. If a stone is being sold at a price that seems too good to be true for a diamond, it might be worth investigating whether it's a moissanite instead.

Why It Matters

Knowing whether a gemstone is a diamond or moissanite matters for several reasons:

Value: Diamonds typically hold their value over time, while moissanite, though beautiful, does not have the same resale value.

Sentimental Significance: Many people choose diamonds for their rarity and natural origin, believing that they represent eternal love. Moissanite, while lovely, doesn't carry the same symbolic weight for some.

Both diamonds and moissanite have their pros and cons, but if you're investing in a diamond engagement ring, it's important to know that you're getting the real deal.

How to Choose Hardness Test (For Beginner)?

Hello, my best friend! How have you been? We haven’t talked to each other for a while.

In this video, I will show you some tips on how to choose the proper hardness tester for your product.

As you know, choosing the wrong hardness tester will waste lots of money!

So follow us, let’s go!

Manufacturers and scientists normally go through the hardness test of any solid material to know the quality or identify the element.

The hardness gives an idea about the material’s characteristic behavior.

The material properties such as resistance, durability, strength, denting, etc. can be determined by doing the hardness test.

Otherwise, it is really hard to know whether the material will serve the purpose or not. Determine the testing method for the test is an important task.

The type, size, and microstructure everything must be considered for that.

So, seriously, how to choose the right hardness tester?

Before we go further, let me tell you something, my old sport.

Just between you and me.

if you are looking to buy a professional and high-quality hardness tester,

please visit our website www.test-hardness.com. and, please, please remember to ask for a coupon!

Keep this secret for me, would you?

Ok, let’s move on.

For testing the hardness of metallic objects, there are a few methods,

like the Rockwell hardness test, the Vickers hardness test, the Knoop hardness test, and the Brinell hardness test.

What is Rockwell hardness test?

The Rockwell test is the most common and easiest method used in the industry.

An indent is there which is inserted into the surface of the material by a major load and then the depth is measured.

It is the quickest and most convenient one used for a larger sample.

What is The Vickers hardness test?

The Vickers test also another one used for measuring the hardness of all types of solid materials.

The diagonal lengths are measured to calculate the hardness of the sample. It is used for both the macro hardness testing and microhardness testing.

What is The Knoop hardness test?

The Knoop test can be the alternative to the Vickers test. It is applicable to materials like ceramic which is brittle and hard as well. The hardness test is done at the micro-level.

The indenter that is used is a pyramidal diamond-shaped and asymmetric.

It is suitable for small areas. It helps to test thin layer hardness like coating. The cracking problem can be solved by this.

What is The Brinell hardness test?

The Brinell hardness test is for materials that have a grain structure and are large in size.

Here a carbide ball is used to measure the hardness optically.

what is Mohs hardness test?

For minerals or rocks, the most common test is the Mohs hardness test.

How to test hardness for woods?

For woods, the most common is the Janka test.

Here, a small steel ball is inserted on the surface and the force is measured to know the hardness.

To get an accurate result, there are a few other factors that must be considered and controlled,

like vibrations, temperature, light, humidity, temperature, etc.

Do you have a good time today?

We will talk about How to test the hardness of rocks at home in the next video.

Don’t forget to subscribe to our channel to watch more videos about professional hardness testers, my dear old sport.

Also, you can check our website www.test-hardness.com to find more information about our hardness tester product and latest industry news.

Stay tuned for the next episode my dear best friend!

I hope you have a wonderful day!

See you.

Cincinnati State Technical College, a Tinius Olsen Success Story

Tinius Olsen has helped one of the leading Technical Colleges in America, the Cincinnati State Technical and Community College, to up-grade and further develop its materials testing laboratory. 

This is the culmination of a partnership between the two organisations that goes back to the establishment of the College in 1969, as Mike DeVore, Professor & Program Chair of the Mechanical Engineering Technology & Welding Technology Dept explains:

“I started teaching at Cincinnati State 29 years ago and at that time we had a very old Tinius Olsen tensile test machine that still worked extremely well on a day to day basis.”   

“Our testing lab had been in operation since almost the establishment of the school so we decided to update our lab in 1993 and, due to the reliability and generally good history that we had with the old machine, I decided to purchase another from Tinius Olsen.” 

“I visited the factory in Pennsylvania and was very impressed with the quality of work and professionalism of the employees at the company, so we purchased our second Tinius Olsen machine, a 60L Super L Tensile Tester. Again we enjoyed great service with the machine until the controls unfortunately failed last year.”

“Fortunately, we had obtained funding to upgrade our materials test lab with all new equipment and it was a relatively easy decision to once again look to Tinius Olsen, thanks in the main to the great experience we have had with the company over the years. It was also important to me to try to purchase American made equipment, whenever possible.”

The machines installed at the Colleges’ testing lab are a 10,000 In/lb Bench Top Torsion Tester, a Model IT406 Pendulum Impact tester, four Rockwell and one Brinnel Hardness Testing machines, as well as retro-fitting the 60L Super L. This has resulted in a substantial investment by the College into their state of the art testing laboratory, which should see at least another 30 years problem free use.

“The new equipment is used in several courses within our Mechanical Engineering Technology, Welding Technology, and Civil Engineering Technology programs. The primary use is in our MET 140 Engineering Materials course where our students spend the semester doing destructive testing.”  

“Between the three programs we have over 500 hundred students - all of which will use this lab at some point in their curriculum.  The tests we currently perform within the lab include Tensile, Bend, Hardness, Torsion and Impact testing as well as Heat treating.”

Cincinnati State Technical and Community College, which is celebrating its 50th anniversary this year, provides student-focused, accessible, high-quality technical and general education, academic transfer, experiential and cooperative education and workforce development.

The College offers more than 130 associate degree and certificate programs through its four academic divisions and the Workforce Development Center.

“We have a long history with Tinius Olsen. We have used their material testing equipment for nearly 50 years here at Cincinnati State and intend to keep the relationship intact for years to come. They are a great American company and we are proud to use their equipment to educate our students,” continued Mr DeVore.

“Through the use of our Tinius Olsen equipment we are able to prepare our students to go out into industry with a thorough knowledge of material testing. Tinius Olsen test equipment is used by many of our employers and they appreciate the fact that our students are learning to use industry standard equipment.”

Pengujian kualitas material dengan hardness testing Rockwell adalah metode umum untuk mengukur kekerasan massal bahan logam dan plastik keras seperti polimer. Meskipun pengujian kekerasan tidak memberikan pengukuran langsung dari daya tahan struktur dan kinerja, kekerasan material berkorelasi langsung dengan cek keaslian material, umur ekonomis, ketahanan aus, dan analisis nilai scrap/Remaining Life Assessment dari bahan material.
