Buying Sterling silver ring with blue created sapphire

Hello. Thank you for visiting my store. This ring is sterling silver with a twisted design around the bezel, and a textured ring shank. The stone has a serrated bezel. It is a created royal blue Sapphire cabochon, and is a 6mm round stone. Created sapphires have the same chemical makeup and physical properties as earth grown sapphire. It is also a 9 on mohs scale of hardness. Which makes it a very good stone for a ring. Size 7 buying
