Among the natural colors of topaz are yellow, orange, pink, red, purple, and blue.
One of the topaz’s most important physical properties is its hardness. As the hardest silicate mineral, it has a hardness of 8.
Topaz crystallizes in an unrestrained cavity forms orthorhombic crystals with striations paralleling the long axis.
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.
That’s surprising for a mineral that consists of aluminum, silicon, and gaseous elements.
The high specific gravity of the mineral causes currents in streams to concentrate it into placer deposits.

The Color Check
Examine the stone’s color closely with the jeweler’s loupe.
For example, the color of an aquamarine will show blue tones and greenish tones.
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.
