This is an 20 inch moissanite and solid silver tennis chain. This is not Cubic Zirconia. Moissanite has more shine and brilliance than diamonds, and these stones will pass a diamond tester. It is a stunning silver necklace that really shines in the light. (Not a choker, please check the length of 20 inch necklaces.) Does not come with this box, just using it as a prop :)
