Hessonite  orCinnamon Stoneis a variety ofgrossular, a calcium aluminium mineral of thegarnet  group with the generalformulaCa3Al2Si3O1 . The name is from theGreekhÄ“ssÅn,inferior, in allusion to its lower hardness and density than most other garnet species varieties.
It has a characteristic red color, inclining to orange, much like that of gemzircon. Indeed it was shown many years ago, by SirA H. Church, that manygems, especially engraved stones, commonly regarded as zircon, were really hessonite. The difference is readily detected by the specific gravity, that of hessonite being 3.64 to 3.69, whilst that of zircon is about 4.6. Hessonite has a similar hardness to that ofquartz, about 7 on themohsscale, whilst the hardness of most garnet species can reach 7.5.

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.
