Cabochons for Jewelry Making & Bezels

A cabochon is a polished stone, glass, or resin piece with a domed top and a flat back — no facets — meant to sit in a bezel or be wire-wrapped, not strung. Match the millimeter size to your setting first: standard cabs run 8x10mm, 13x18mm, 18x25mm, and 30x40mm, plus rounds from 6mm to 25mm. Calibrated cabs are cut to exact dimensions so they drop into commercial bezel cups; freeform pieces need a custom or hand-formed bezel. Natural-stone cabs (turquoise, agate, labradorite, jasper, druzy) vary in pattern, so look at the actual photo, not a stock image. Expect roughly $4-$15 for common agate or glass cabs, $15-$60 for labradorite, druzy, or opal doublets. Many makers ship loose cabs in 3-7 business days; hand-cut or custom-shape orders run 1-3 weeks. Check whether the back is flat (bezel-friendly) or slightly domed (better for glue-on settings).

Use the size, shape, and material filters to match your bezel, then scan related searches for specific stones like druzy or labradorite.
