Bertrandite Refractive Index
Optical properties of a Bertrandite 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 Bertrandite.
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. So if you are searching for prominent Colorless Gems, Bertrandite gem is something not miss on, since it has been a favorite pick in the gem wearing community.
