Thank you for viewing! Set of 6 synthetic stones in various colors, perfect for a variety of designs. - Colors: 6mm blue spinel, 8mm ruby, diamond topaz - Shape: Round - Quantity: 3 of 6mm, 3 of 8mm Thank you for looking. I purchased these for making silver clay accessories, but I haven't been making them for a while, so I'm selling them. These synthetic stones can be fired with silver clay. Please feel free to ask if you have any questions. I may be slow to respond due to work. Simple packaging. I may use recycled materials for packaging when shipping. Thank you for your understanding. Although unused, they have been stored at home, so there may be some discoloration or scratches. I don't smoke, but I do have a cat. Please refrain from purchasing if you are looking for a perfect item.
