Wernerite Refractive Index
Optical properties of a Wernerite crystal are responsive to the small changes in composition and strain within its crystalline structure. Absolute diligence is therefore necessary during cutting and polishing of the gemstone. All such optical properties are majorly influenced by Physical Properties of Wernerite.
As we are well aware, refractive index is the phenomenon which is related to bending of light through a medium (crystal). It is used in qualitative analysis of gemstones by gemologists Besides, few gemstones exhibit property of dual refractive indices. This dual nature is known as Birefringence. The value of Wernerite refractive index is 1.531-1.600. Birefringence value for this gem is 0.004-0.037. So if you are searching for prominent Gems Found In Africa, Wernerite gem is something not miss on, since it has been a favorite pick in the gem wearing community.
