Many jewelry makers love working with cabochons. You could bezel them with beads or wire wrap them. Or glue them onto metal bezels if the sizes fit.
There are some gorgeous gemstone ones as well as those made from clay. But have you considered photo glass cabochons? The designs can be very colourful indeed.
Do check out my links at the end for past posts for resin tutorials. Clear resin has the look of glass but is much lighter.
