Ladies sterling silver pendant featuring the man-made gemstone rainbow calsilica. Despite being slightly larger, at twenty grams this pendant is surprisingly light weight.
Rainbow calsilica is the only man-made stone that we feature in our collection of rocks and minerals and we do so because of its curious and fascinating history. First introduced some years ago to the rock and mineral community as a natural rock from Mexico, it quickly attracted worldwide attention but all was not as it seemed. After several investigations chemical analysis revealed that rainbow calsilica was actually made up primarily of crushed calcium carbonate rock and the colour was the result of various dyes. It has never been discovered exactly who was behind the creation of this geological hoax but the idea was ingenious and incredibly audacious considering its first appearance was at the world's largest rock and mineral fair.
Our rainbow calsilica pendants have always been popular hence for the time being we still include this colourful man-made material as part of our collection. Read more about the story of rainbow calsilica in the Articles and Photos section of our website.
