Light blue resin tints the iridescent display of the marbled paua shell that lies within this 18mm round cabochon. The result is a gorgeous display of purple, green, blue and marbled black. The cabochon is made by trapping a paua shell between a black resin back and a transparent light blue curved resin front. Use this cabochon for craft projects or fashion accessories. Paua shell comes from New Zealand, where its coloring and iridescent properties have made it popular with tourists. Because the shells are natural, each cabochon will have a different pattern.
