Simple, fun sliders! Kind of a "fidget" thing, at least for me. Pictured left to right: Peach Moonstone, Apatite, Obsidian, Unakite, Aventurine, (triple) Peach Moonstone, Amethyst, but you can choose most any natural gem bead. Single gem bead is $25, triple with stainless steel spacers is $35. Typically, the stainless steel chain is about 16" with a 2" extension - you want the bead(s) to land just a bit below your collarbone.
