Description

Tanzanite is a gemstone, a blue-to-violet variety of the mineral zoisite, named after Tanzania, its sole source near Mount Kilimanjaro. Discovered in 1967, it is prized for its vibrant colors, which are enhanced by heat treatment and depend on the viewing angle due to pleochroism. Tanzanite measures 6.5 to 7 on the Mohs scale of hardness, making it brittle and requiring careful handling and cleaning.

Why are users outbidding themselves?

Automatic Bid icon
Automatic Bid

When a bid is placed, this is the maximum amount a person is willing to bid for the product. Our system will then automatically bid on behalf of the bidder, incrementally increasing the bid up to the maximum to maintain their position as the highest bidder.

When there is an icon indicating 'Automatic Bid', it means our system is actively placing bids for the bidder based on their maximum bid. This may appear as if bidders are outbidding themselves, but it's simply a result of the system updating the bid to reflect the bidders maximum limit.
