I am selling this item because I no longer use it. Although there is no "Silver 925" stamp, it has been appraised as silver by a buyer. However, please understand that this is not a guarantee. I will only sell to those who agree to no claims and no returns. The stones, from top to bottom, are, I believe: Tiger's Eye, Onyx, and Amethyst. I cannot guarantee this, so please check the images carefully before purchasing. Material: Silver
