Rainbow Calsilica Man-Made Stone
Colourful rainbow calsilica cabochon mounted in fine sterling silver.
Believed to have originated in Chihuahua in Mexico, this distinctive stone which is man-made is used primarily in jewellery.
Although sometimes likened to fordite which is hardened car paint, rainbow calsilica is a different material.
The story of rainbow calsilica is curious and fascinating. The people behind its creation went to extraordinary lengths to convince the world it was a natural stone.
It's now widely known to be man-made but few if any details have ever emerged about who was behind its production.
