These small tumble polished gemstone bits can be used for a variety of creative applications including nail art, home decor, pave jewelry and crafts. Bits sized at #3 range from 8mm to 15mm (when measured along the longest length of each piece), however some pieces included in your order may be larger or smaller due to the nature of how the bits are sorted. These gemstone chips are produced as byproducts of the lapidary crushing process and as a result, inventory is not always readily available so supplies are limited.
