Labradorite Luster

Optical Properties of Labradorite are its behavioral responses towards light. While few optical properties can be identified with naked eyes, other require special instruments by the gemologists to identify them. Labradorite optical properties like luster, clarity, refractive index etc. are used to determine the non-destructive methods during gemstone identification and evaluation.

Labradorite luster is the quantity of light the crystal reflects when light is incident on it. Labradorite which is commonly found in Violet, Colorless, gray, White, Green color, is Translucent, Transparent and Transparent to translucent in nature. It possess Pearly and Vitreous luster.

Labradorite Refractive Index

Optical properties of a Labradorite 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 Labradorite.

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 Labradorite refractive index is 1.554-1.573. Birefringence value for this gem is 0.008-0.010. So if you are searching for prominent Gems for Aquarius, Labradorite gem is something not miss on, since it has been a favorite pick in the gem wearing community.
