Thunderbird offers more than just beads, tools, and stones. We also like to get into direct details for metalsmithing. We have a large selection of Sterling silver discs (blanks) on hand to help with any projects like stamping, bead forming, earring sets, and bezel cups. Available gauges are 20, 22, 24, 26, and as light as 28. Varying in sizes from 1/4'' up to 2'' diameter. We’re here for your main jewelry supply stop — A great place to shop smart.
