Thank you for looking. A set of 6 synthetic stones in various colors, perfect for a variety of designs. - Colors: 6mm Blue Spinel, 8mm Diamond Ruby, Diamond Topaz - Shape: Round - Quantity: 3 pieces of 6mm, 3 pieces of 8mm Thank you for looking. I purchased these to use when making accessories with silver clay, but I haven't been making them for a while, so I'm putting them up for sale. These are synthetic stones that can be fired together with silver clay. Please feel free to ask any questions. I may be slow to respond as I am working. Packaging will be simple. I may use recycled materials for shipping. Thank you for your understanding. These are unused items, but due to home storage, there may be fading or scratches. I do not smoke, but I do have a cat. Please refrain from purchasing if you are looking for perfection.
