A distinct cleavage occurs at the basal surface, resulting in vitreous fracture surfaces perpendicular to the crystal’s long axis. 

Despite topaz’s hardness of 8, it is a more fragile gemstone because of its cleavage.

Topaz is a very hard stone, but it is prone to chipping or cleaving because it has a low tenacity.

Topaz’s specific gravity is between 3.4 and 3.6.

The Color Check

Examine the stone’s color closely with the jeweler’s loupe.

Since a blue topaz is artificially colored, it will only contain blue tones.

The Birefringence Check

The refraction lines of blue topaz are more prominent than those of aquamarine.

Use the jeweler’s loupe to look at your stone closely.

Topaz is easily recognizable by two lines of refraction on its surface.

Usually, aquamarines do not possess this birefringence.

Diamond Tester Thermal Test

With a diamond tester, you can determine if your stone conducts heat by measuring its thermal conductivity.

For example, Beryl gemstones, including blue topaz, are conductors, whereas aquamarine is not.

Therefore, it is a blue topaz if it conducts heat.
