Marbled black and green patterns shine just beneath the surface of this 13mm round emerald paua cabochon. The cabochon features a genuine paua shell layered between a black resin back and a rich green curved resin top. Paua shell comes from New Zealand, where its coloring and iridescent properties have made it popular with tourists. Shells with similar properties in the USA are not as vibrant in color and are known as abalone. Because the shells are natural, each cabochon will have a different pattern. Feel free to browse for other cabochons.
