Sterling Silver Infinity Diamond Twist Necklace. There is some tarnish from age. I believe the stones in the center and bottom are Moisanite Diamond. Since the diamonds are so small it does set off the Diamond tester but it also catches the metal so it is not a great reading of the stone so I can o my assume it is moisanite Diamond. Chain is 18 inches in length and is tarnished. Chain is a twist link and the clasp is marked 925 sterling silver. Pendant is 1.25 inches in length. Is marked 925 sterling silver and has another hallmark I cannot identify. I do accept best offers so please feel free to leave one! Happy buying!
