A star sapphire is a type of sapphire that exhibits a star like phenomenon known as asterism.Star sapphires contain needle like inclusions that cause the appearance of a six star ray.
TREATMENT
Diffusion treatment is a popular method for treating star sapphire, as the treatment will increase the asterism the star effect in sapphire and ruby) The diffusion process may reach half a millimeter of depth into the gemstone. The process creates the star effect on the gemstone and the stone can be sold as a diffused star sapphire. The hardness of the gemstone is not affected by the diffusion process and the gemstone therefore keeps its original physical properties. A sapphire made into a diffused star sapphire cannot be polished or recut for the second time as the treatment is only on the surface of the stone. Polishing or recutting would take off this surface treatment. However, most buyers never repolish or recut the gemstones set in jewelry. This is especially true of sapphires, as they are hard and scratch resistant gemstones.

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.
