Caledonite Luster

Optical Properties of Caledonite 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. Caledonite optical properties like luster, clarity, refractive index etc. are used to determine the non-destructive methods during gemstone identification and evaluation.

Caledonite luster is the quantity of light the crystal reflects when light is incident on it. Caledonite which is commonly found in Blue, Green, Blue, Green, Green color, is Transparent in nature. It possess Vitreous luster.

Caledonite Refractive Index

Optical properties of a Caledonite 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 Caledonite.

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 Caledonite refractive index is 1.818-1.909. Birefringence value for this gem is 0.091. So if you are searching for prominent Blue Gemstones, Caledonite gem is something not miss on, since it has been a favorite pick in the gem wearing community.
