Green Optical Calcite

Green Optical Calcite 

Green optical calcite, also known as Iceland spar, is a variety of calcite that exhibits unique optical properties.

Green optical calcite is formed from the metamorphism of limestone or marble under high temperature and pressure conditions. It is primarily found in locations where these carbonate rocks have undergone significant geological processes, including regions in Iceland, Mexico, and the United States.

Green optical calcite typically occurs in transparent to translucent crystals with a vitreous to pearly luster. Its color ranges from pale green to deep emerald green, often with cloudy or streaky patterns due to mineral impurities. One of its most notable features is its double refraction property, where light passing through the crystal is split into two rays, creating a double image. This effect can be observed when viewing objects through a piece of optical calcite, making it a fascinating and sought-after mineral specimen for both collectors and enthusiasts.
