This exceptional Optical Calcite specimen from Maharashtra, India weighs 1.02 lbs and measures approximately 3.8 in x 2.7 in x 2.5 in, featuring outstanding clarity, strong rainbow refraction, and a vibrant fluorescent response under ultraviolet light.
The specimen displays the remarkable optical properties that have made Optical Calcite famous among mineral collectors and educators. Its high clarity allows for the classic double refraction (birefringence) effect, where text and objects viewed through the crystal appear doubled. Internal light dispersion also produces beautiful rainbow reflections throughout the specimen.
Under 365nm UV light, the crystal exhibits a vivid red fluorescence caused by naturally occurring manganese within the calcite structure. The combination of strong optical performance and UV reactivity makes this an especially desirable collector specimen.
Material from Maharashtra, India is highly regarded for producing attractive optical calcite with excellent transparency and display quality.

Mineralogical Notes:
Calcite is a calcium carbonate mineral known for exhibiting one of the strongest natural birefringence effects found in minerals. Trace manganese within the crystal structure is responsible for the red fluorescence visible under longwave ultraviolet light.
Collector Notes:
High-clarity optical calcite specimens that combine strong birefringence, rainbow refraction, and UV fluorescence are highly sought after by mineral collectors, fluorescent mineral enthusiasts, and educational collections.
