The main inquiry which arises repeatedly during your search for moissanite jewelry or your online sale of it exists as follows: 

Does moissanite pass a diamond tester?

The short answer is YES — most standard diamond testers will show moissanite as “diamond”.

What Is a Diamond Tester?

The diamond tester operates as a portable instrument which determines gemstone identity through its ability to measure thermal conductivity and electrical conductivity. 

How Diamond Testers Work

• The probe sends heat into the stone
• The system measures the speed at which heat moves through the material
• Diamonds conduct heat with extreme efficiency
• The tester indicates a diamond when heat moves through the material at high speed

Key Point:

The diamond testers measure conductivity of gemstones but they do not measure their rarity or their origin or their market value.
