Description about Grandidierite:
Grandidierite is an exceptionally rare and beautiful gemstone, known for its striking blue-green to teal color. It was first discovered in Madagascar in 1902 and named after the French explorer Alfred Grandidier. The gemstone’s distinctive hue is a result of trace amounts of iron in its structure, and it can exhibit pleochroism, meaning it shows different colors—typically blue, green, and colorless—depending on the angle it is viewed from.
With a hardness of 7.5 on the Mohs scale, grandidierite is durable enough for jewelry, though its rarity often makes it a collector's stone rather than one used in everyday wear. It is primarily sourced from Madagascar, but smaller deposits have also been found in places like Sri Lanka and Namibia.

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.
