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.

GemSelect is always my first choice for purchasing gemstones. The fact that the gems are always exactly as described and pictured on the website has earned my trust many times over. Even when I don't buy, I still love browsing all the beautiful stones. My new favorites are the bright green Tsavorites!
