Sterling silver with real black diamond in middle and small diamonds on the sides. Will meet at jewelry emporium in Cookeville so we can go in together and they can tell you it’s real and it’s worth. Beautiful ring. 400 dollars.. I have already been there and they told me what it is wroth. If interested let me know a time you’re available to meet there and I’ll see if I can meet at that time or we can figure out a time. would be a great Valentines gift.Thanks # click for number
