Color change spinel navy sapphire blue in natural light to a purple blue color under inside light. Complete color change. Sri Lankan spinel gemstone. I try to price my stones below other sellers and try to make sure all customers are getting a true gemstone at a bargain price. This one most likely has cobalt. It has the right color and the right color change. Goes from royal blue to violet blue to pure violet. These blue stones I have been collecting from the Sri Lankan market as they come in. There is a small crystal inclusion under the table facet on this stone. The price I think reflects that. It is barely visible looking at the stone back lit with the naked eye.
There is an article on this site about blue spinel titled “The rarest of them all”. It is located in the learn section under Additional Gemstone Information. Spinel is rarely treated or heated as it naturally comes without many inclusions and heating does nothing to increase the beauty of the stones. Spinel is rapidly becoming more popular. I’ve heard many gem affectionados state it was their favourite gemstone. It was once thought to be sapphire or ruby depending upon the color. The imperial crown housed in the tower of London has a large red spinel which was once thought to be a red ruby. It is named the Black Prince’s Ruby and has a recorded history dating back to 1366 AD. Cobalt is the main colorant in blue spinels and are especially rare. For me I prefer them over sapphires. The better price, less inclusions and lower cost make it the better value. It is also a hardness of 8 which is only slightly under sapphire so is good for everyday wearing.

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.
