Shell has well known as the main raw material from which cameos are cut. Most common in fairly sheltered areas, on bottoms of coarse coral sand. This organic round with the Wrinkle of a shell of the Red Cypraecassis Rufa. It is a unique specimen in Jewellery.

The cypraecassis rufa shell comes from a large snail of the same name. It is also referred to as the 'cameo shell', because of its use in jewellery as cameo engraving. The silver ring has been fashioned in a way that it complements the natural texture of the rufa.
