Genuine moonstone ring. If you are looking for the most valuable moonstone, look for one that is colorless with a blue sheen. You can get moonstones in different colors such as green, orange, brown, and gray with blue, white, or rainbow adularescence, but the colorless ones are the most valuable. This is a very high grade of moonstone. You can see in the pictures the blue sheen and against the almost icy looking moonstones. Each is prong set and has white zircon accents to add sparkle in between. The setting is solid sterling silver with platinum overlay. This is new with tags and will come in a gift box. It has the hallmark inside the band. STS 925. Size 7 Jewelry from QVC, HSN, JTV, Gemporia, Kay Jewelers, Shop LC, Shop HQ, Chuck Clemency, and STS Jewels Inc.
