Product Details

Extremely Rare Gemstone, 1.81Ct Madagascar Moroxite, Green Apatite Moroxite is the blue/green gem variety of apatite, a calcium phosphate mineral crystallizing in the hexagonal system. The characteristic blue to blue-green coloration is typically attributed to trace elements such as manganese and rare earth elements. With a Mohs hardness of ~5, refractive index ranging from approximately 1.63–1.65, and birefringence up to 0.008, moroxite exhibits moderate double refraction and a vitreous luster. Specific gravity averages 3.16–3.22.
