Most of my loose beads can be used as focals. Focals come in many sizes, shapes & colors. While it's not necessarily the case, as the name implies, a focal is intended to be the center of attention in whatever it's used in.
Please keep in mind that I'm a beadmaker and not a photographer. I try really hard to capture the correct colors, but due to variations in lighting, and monitor settings, the colors may vary a bit. Sizes are approximate, within a mm.
