What can you test with a diamond tester? 5 Key Functions Explained

A diamond tester is a specialized tool used to verify the authenticity of diamonds.

It helps distinguish real diamonds from imitations and differentiate between natural and synthetic diamonds.

Additionally, it can detect if diamonds have been treated and identify certain diamond simulants like moissanite.

What can you test with a diamond tester? 5 Key Functions Explained

1. Distinguishing Real Diamonds from Imitations

Diamond testers use either thermal conductivity or electrical conductivity to identify genuine diamonds.

Genuine diamonds have unique thermal and electrical properties that set them apart from imitations like cubic zirconia.

These testers can accurately check for fake diamonds or cubic zirconia because these materials do not have the high thermal conductivity of real diamonds.

2. Differentiating Between Natural and Synthetic Diamonds

A diamond tester can tell earth-mined diamonds from man-made synthetic diamonds.

This is crucial in the jewelry industry where synthetic diamonds are becoming increasingly common and difficult to distinguish with the naked eye.

Some advanced testers use ultraviolet short waves, which are more effective than traditional heat and electrical conductivity methods, especially in identifying synthetic diamonds that might fool normal diamond testers.

3. Detecting Treated Diamonds

Diamonds that have undergone treatments to enhance their color or clarity can also be identified using a diamond tester.

This is important for determining the true value of a diamond, as treated diamonds are generally less valuable than untreated ones.

4. Identifying Diamond Simulants

Some diamond simulants, particularly moissanite, can closely mimic the properties of diamonds.

Traditional diamond testers may not distinguish between diamonds and moissanite, but newer models equipped with electrical conductivity testing can accurately identify these simulants.

This is crucial for ensuring the authenticity of diamonds, especially in high-value transactions.

5. Additional Features

Some diamond testers come with additional features such as magnification lenses for a more thorough inspection of the diamond's surface and interior.

This helps in identifying blemishes, inclusions, and other anomalies that could indicate a fake or low-quality diamond.

Metal detection features are also available in some testers, which alert users to accidental touches on metal surfaces that could affect the test results.
