Blue Paraiba tourmaline and white diamond simulants 2.77ctw oval and round and white diamond simulant 0.37ctw round, rhodium over sterling silver ring. This is an exquisite ring that looks like the ocean in the Caribbean. It is stamped by the jeweler and 925. Size 6 ** All of my jewelry comes in a nice ring box and is in excellent condition. I take the time to check each prong and hand polish the rings before I pack them up for shipping. Please keep this in mind when you send me offers. I put a lot of time and energy into every order. I will also send you a pair of earrings or another type of jewelry as a gift with your purchase. I'll always ask you for your opinion so that the gift is something you will enjoy. Customer satisfaction is my top priority!
