This huge sri-lankan (ceylon) blue/clear sapphire is a collectors oddity for sure. It has a well faceted pear/teardrop design and some pretty unusual characteristics such as the blue hexagonal colour zoning, and some very heavy veils/fingerprints (healed fractures) giving the inside of the gem a wispy or smokey internal appearance.
This gem has been assessed under 400x magnification, Long-wave UV, short-wave UV, refractometer and polariscope and determined to be natural sapphire, heat treated only. These types of veils are uncommonly seen in finished gemstones especially of this size and are magnificent under a microscope. This gem has been used for gemological training around inclusions from sri-lanka and is no longer needed.

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.
