I did not realize these stones were of jewelry quality. They are really beautiful, just not what I was expecting which was more of a natural stone.

My current project is something BLUE . Opal earrings with matching tennis bracelet for her wedding. The opals and sixty two sapphires VVS & VS are AMAZINGLY BEAUTIFUL. The private jewelers were impressed by the clarity and inclusion free of the sapphires . I want to say thank you for the High quality sapphires that I purchased for my daughtera's wedding.
