Danburite is one of those gems that isn’t often seen in today's market. It’s a hard and durable stone which makes it great for jewelry, and it has a higher refractive index than Beryl, Tourmaline or Topaz! Danburite is truly only found in a few places in the world in fine facet-grade material. It’s not an extremely rare gem, but there is only one locality (Charcas, Mexico) that produces superior quality stones in larger sizes. This particular gem is a large, bright, attractive, colorless Wide Cut Korner Kite cut stone. You don't see many 7+ (!) carat Danburites around, so don't miss out on this one. Stones like this are certainly above "collector quality", and would make a very worthwhile addition to any gem collection.
