Abalone is an organic gem formed from the protective layers of calcium carbonate that build up inside and outside the abalone shell. The colour is the abalone shell changes when viewed at different angles. This iridescense, similar to that of Mother of Pearl shell, but even more brilliant, is what makes the abalone shell so amazing and considered as a gem material for use in jewellery. This particular specimen is formed from the green hues. These slabs are made from gem quality shell, which only comes from the oldest abalone with the thickest shell. Each of these slabs is produced from a selection of over 12 000 pieces. For indoor use only.
