OTC Thailand sterling silver diamond cross necklace

Sterling silver necklace with sterling pendant. Pendant is shaped like a stylized cross with a band of 7 small diamonds (confirmed with Presidium Gem Tester II, as shown in photos). Both pendant and chain are marked 925 OTC, and the pendant is also marked Thailand. Necklace is in good condition with no known flaws. Comes in a box that I do not think is original to the necklace, as the branding does not match. This is a used necklace, despite the newer looking packaging. The smaller card inside the box that the necklace is stored in does show signs of wear. Quarter shown for scale. Will not be included with your order. Chain is approximately 17.5".
