If you have one of those rectangular turquoise bar necklaces with Kingman turquoise, and you have a 6.25 ring-size, this may be a, er, good fit. The Kingman turquoise here is beautiful and has a hint of green within the prominent blue. This ring is 1 and 1/8th-inches long and almost three-quarters-of-an-inch wide. Weight is 7.3-grams, or .26-ounces. The maker might not have intended to sell it, or he or she may have just neglected to add a hallmark. Complimentary USPS tracked Priority shipping within the U.S.
