Shimmering iridescent color marbles with black lines to create a beautiful display just under the surface of this 10x8mm oval natural paua cabochon. The cabochon is made by placing a paua shell between a black acrylic base and a transparent acrylic dome. You'll find colors ranging from orange and yellow to green, purple and blue. 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.
