Grandidierite is a rather rare mineral, with a lovely blue-green color. It is never transparent enough to facet, but attractive, sometimes even jadelike cabochons are cuttable from the translucent material. The high hardness makes it suitable for wear, although cutters have to pay close attention to the cleavage. Cut grandidierite is seldom seen in collections because few collectors have even heard of it or know it exists in cuttable form. Forbes magazine and GIA article classify Grandidierite as the second extremely rare gemstone.
Grandidierite features a deep blue-green color that is often too opaque to facet. The hardness of the gem makes attractive fine jewelry, but cutters must be careful when shaping the stone to avoid fractures. Jewel experts typically cannot set a specific price for the gem, but they generally estimate about $20,000 a carat.

Why are users outbidding themselves?
When a bid is placed, this is the maximum amount a user is willing to bid for the product. Our system will then automatically bid on that users behalf, incrementally increasing the bid to maintain their position as the highest bidder, up to the specified maximum.
When there is an icon indicating 'Auto Bid,' it means our system is actively placing bids for the user based on their maximum bid. This may appear as if users are outbidding themselves, but it's simply a result of the system updating the bid to reflect the users maximum limit.
