A shimmering paua shell marbled with black lines creates a unique pattern just under the surface of this 10x8mm emerald oval paua cabochon. Try adding this cabochon with silver flower charms to create a nature theme on a purse or hair barrette. The cabochon is made by placing a natural paua shell between a black acrylic base and a transparent green acrylic dome. Paua shell comes from New Zealand. Because the shells are natural, each cabochon will have a different pattern. Be sure to explore other sizes and styles of cabochons.
