Donut beads (or donut pendants) are a large disk with a very large hole. This shape is also known as a ring. You can turn gemstone donuts into quick pendants using 1mm - 2mm leather or cotton cord, and a simple larks-head knot. For something fancier, capture the donut with a wire-wrap, wire-weave, or seed beaded design. Skip a clasp by making the necklace long enough to slip over the head, or add a clasp to make a shorter necklace. Odds are, you already know what you want to do... you're just looking for the right size and stone! Availability varies -- so when you find a batch you like, stock up before they're gone.
15mm gemstone donuts: Are they beads, or are they focals? It's up to you -- 15mm gemstone donuts are a nice size for earrings and petite bracelet centerpieces.
25mm (1" diameter) gemstone donuts can be simply tied with ribbon or leather, or they can be seed beaded, wire wrapped and more.
30mm, 35mm and 40mm donuts work with medium (16mm) donut bails.
45mm - 50mm donuts work with 26mm (large) donut bails.
