Understanding Lab Grown Diamonds and The Use of Diamond Testers
Differentiating between lab grown diamonds and mined diamonds can be hard for the layman. Even diamond experts have to rely on special equipment or devices to help them assess diamonds.
In this blog, we focus on how laboratory diamonds can be tested using diamond tester equipment.
What is a diamond tester?
A diamond tester is a device or a machine that is used to check the authenticity of diamonds. The device measures the thermal conductivity of diamonds to ascertain whether a diamond is mined or synthetic diamond.
How Do Specific Diamond Testers Work?
But how exactly does the diamond tester work? The diamond tester works in two ways:
1. Thermal conductivity test: The diamond tester measures how quickly a material dissipates heat and based on that one can know if it’s a mined diamond or a lab grown diamond.
2. Electrical conductivity test: In this method, an electric current is sent through the lab grown diamond to measure its resistance, based on which, the type and origin of a diamond is ascertained.
Do lab grown diamonds pass diamond testers?
There’s hardly any difference between mined diamonds and lab grown diamonds. Both types of diamonds have similar chemical compositions. That’s because both are made through the same process and are identical in appearance.
However, because laboratory diamonds grown are created in controlled environments, they have lesser inclusions, and more clarity and higher color quality compared to mined diamonds.
So, are lab-grown diamonds considered real even though they are created through artificial process simulations?
The answer is a definitive yes! Engineered diamonds are also considered real diamonds just as mined diamonds.
How to differentiate a lab grown diamond from a mined diamond?
We’ve discussed and understood how lab diamonds can pass under diamond testers and be tested as real diamonds. But then the question is how can one distinguish between a lab grown diamond and a mined diamond only based on a diamond tester?
That’s where a more detailed and thorough diamond examination is required.
The 4 Cs of diamond to distinguish lab diamonds and mined
There are many diamond institutions that have created standard ways of assessing diamonds. These methods help differentiate lab and mined diamonds. One such institution is the Gemological Institute of America (GIA). GIA has standards for measuring the 4 main characteristics of diamonds — the 4 Cs of diamond— cut, clarity, color, and carat.
Cut
The word "cut" doesn't only apply to lab grown diamond shapes, such as round, oval, heart, pear, etc. The cut of a diamond also provides a diamond with its angles, facets, proportions, and finishing. The lab diamond's cut determines its performance and brilliance, making it the most crucial element.
Here’s the standard diamond cut grade chart to help you choose the best lab grown diamonds.
Color
Even though diamonds appear colorless, a closer inspection may reveal some hues or colors. There are a wide range of colored lab grown diamonds as well. Diamond colors are ranked in alphabetical order.
-
D is regarded as the ideal shade for a diamond.
-
As the diamond color begins to turn yellow or brownish, they are graded as E, F, G, H, and so forth.
Here is a diamond color grading chart you could use as reference for your synthetic diamonds:

Clarity
Clarity refers to the diamond inclusions (internal characteristics) and blemishes (external characteristics) in diamonds. Inclusions and imperfections are graded according to their size, type, and location.
Carat
Carat weight is another of lab diamonds’ 4Cs. A diamond's weight is measured in carats. Carats weigh 0.200 grammes. 100 points can be used to divide up each carat. Some of the popular carat weight sizes are: 0.5 carat, 1 carat, 1.5 carat, 2 carat lab diamond, 2.5 carat, 3 carat, 4 carat lab grown diamond, and 5 carats.
FAQs
Question: Do lab grown diamonds pass the diamond tester?
Answer: Yes, lab diamonds will pass diamond testers because they are as real as mined diamonds. Lab diamonds are identical and equally strong and hence will pass diamond tester tests.
Question: How real are lab diamonds?
Answer: Engineered diamonds have the same chemical and physical properties as mined diamonds. They are as real as mined diamonds.
Question: Is it easy to tell the difference between mined and laboratory diamonds?
Answer: Lab grown diamonds and mined diamonds are similar. However, a diamond expert can tell the difference between the two with the help of a diamond tester.
Question: What is the price of lab grown diamonds and mined diamonds?
Answer: Mined diamonds are at least 50 to 60% more expensive than lab grown diamonds. Lab diamonds are an affordable and cost-efficient choice.
