The world's largest deposit, containing roughly 80% of global reserves. Known for producing some of the highest-quality crystal

Typically found in colors ranging from honey-yellow to reddish-brown . While the mineral itself is common, transparent, gem-quality crystals are extremely rare and valued for their high refractive index, which gives them exceptional brilliance and "fire". Major Deposits: bastnasite
