Rainbow calsilica pendant crafted in a highly polished sterling silver setting. This funky gemstone makes a great piece of ladies jewellery and one that's sure to attract plenty of attention. When first introduced to the commercial market some years ago the supplier said it was a natural stone which comes from the state of Chihuahua in Mexico. It quickly attracted the attention of geologists and mineral enthusiasts from around the world and before long some difficult questions were being asked.  Although the world's only supplier insisted it was completely natural, he wouldn't reveal the exact location where it was mined because he said the owners of the land wanted to protect rainbow calsilica from exploitation.

As experts became increasingly suspicious, samples were sent away for in-depth analysis and the results confirmed that rainbow calsilica was in fact man-made. Although traces of the minerals hematite, celestine and calcite were present, other coloured pigments were not natural and many of the particles seemed to be bonded together with a plastic-like substance similar to paraffin wax. The supplier of the sample argued that he imports rainbow calsilica directly from Mexico in large slabs and his company stabilises it with an epoxy which increases its durability. He claimed it was that resin that was showing up in their tests.

Rainbow calsilica fooled the rock and mineral community for some time and many wholesalers and retailers still insist today that it is a natural stone.  I think we can confirm with some degree of certainty however, that it is indeed man-made but it's definitely a material with a story behind it and for the time being, we still enjoy featuring this "gemstone" in our collection.
