Others claim that Calsilica, or "Rainbow Calsilica", is a naturally occurring material. However, all seem to agree that Calsilica, just like Turquoise, is most of the time stabilized to keep it from flaking, and protect the colors when being worn as jewelry.
Calsilica specimens can be quite beautiful and colorful, and as such, can be used too make earrings, pendants, beads, rings, and other items. As seen to the right, a necklace of graduated Calsilica beads put together by Jay King, becomes quite dramatic on its own. While the purists amongst us may be disappointed that Calsilica is perhaps man-made or man-modified, Calsilica continues to capture the imagination of jewelry designer as well as jewelry wearers alike. It is really any different that the common practice of stabilizing Turquoise? The key in the future of Calsilica may be seeing the mine and determining if colorization in addition to the stabilizing, is being done on the natural stone.
