Diamond testers are widely used to distinguish between real diamonds and other gemstones or simulants. They work by measuring the electrical conductivity and thermal conductivity of the stone, which are unique properties of diamonds. Lab-created diamonds, which have the same chemical and physical properties as natural diamonds, will pass these tests just as natural diamonds do. This is because lab-grown diamonds are real diamonds, differing only in their origin. Additionally, reputable lab-grown diamonds often have microscopic laser inscriptions that can be used for identification under magnification.
Key Points Explained:
-
How Diamond Testers Work:
- Diamond testers measure two key properties: electrical conductivity and thermal conductivity. These properties are unique to diamonds and help differentiate them from other gemstones or simulants.
- Since lab-grown diamonds have the same chemical and physical structure as natural diamonds, they exhibit identical conductivity properties and will pass diamond tester evaluations.
-
Lab-Created Diamonds vs. Natural Diamonds:
- Lab-created diamonds are real diamonds. They are made of pure carbon and have the same crystal structure as natural diamonds.
- The only difference between lab-grown and natural diamonds is their origin. Lab-grown diamonds are created in controlled environments, while natural diamonds are formed over millions of years in the Earth's mantle.
- The term "synthetic diamond" can be misleading because it implies that lab-grown diamonds are not real, which is not the case. They are chemically and physically identical to natural diamonds.
-
Microscopic Laser Inscriptions:
- Reputable lab-grown diamonds often come with microscopic laser inscriptions on the girdle of the stone. These inscriptions are used for identification and are only visible under intense magnification.
- These inscriptions provide an additional layer of verification, ensuring that the diamond is lab-grown and not a natural diamond.
-
Limitations of Diamond Testers:
- While diamond testers are effective in distinguishing diamonds from other materials, they cannot differentiate between lab-grown and natural diamonds. Both types will pass the test.
- For consumers or jewelers seeking to identify the origin of a diamond, additional methods such as checking for laser inscriptions or advanced laboratory testing are required.
-
Consumer Considerations:
- For buyers, understanding that lab-grown diamonds are real diamonds is crucial. They offer the same beauty and durability as natural diamonds but often at a lower cost.
- When purchasing a diamond, especially a lab-grown one, it is important to buy from reputable sources that provide proper documentation and inscriptions for verification.
In summary, diamond testers are reliable tools for confirming whether a stone is a diamond, but they cannot distinguish between lab-grown and natural diamonds. Lab-grown diamonds are real diamonds and will pass all standard diamond tests. Consumers should be aware of the similarities and differences between lab-grown and natural diamonds and ensure they purchase from trustworthy sources.
