Impressive Rainbow Calsilica Pendant
Rainbow calsilica pendant crafted in fine sterling silver. This unique looking gemstone makes a great piece of ladies jewellery and one that's sure to attract plenty of attention. When first introduced in 2002 the supplier claimed it to be a natural stone mined in 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 natural, he wouldn't reveal the exact location where the stone was mined because he said the owners of the land wanted to protect the mine 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 may not be a natural stone but it remains a popular and widely used lapidary material particularly for items of jewellery. This cabochon demonstrates incredible attention to detail because when gently moved around in good light, minute sparkling crystals can be seen just beneath the surface of the stone.
