These beads are about 412-15mm thick, sliced and polished and drilled by my dad, in Oregon. He's one of those old rockhounds who love searching for beautiful stones and making them into something others can use or wear.
You are looking at a group of three real amazonite beads with gorgeous patterns, formed by nature, in a lovely mixture of bright aqua and white. Hole is about 2mm so it would be easy to wire-wrap or use a fine cord here. The hole is chamfered so that there isn't a sharp edge. Quarter for scale.
