Large Rainbow Calsilica Stone
A large rainbow calsilica stone with a dull lustre. Stones with a dull lustre absorb light instead of reflecting it.
Rainbow calsilica is a colourful, man-made stone first introduced to the world some years ago. It was said to be a natural material from Chihuahua in Mexico.
After careful examination, geologists confirmed that although some natural minerals were present, rainbow calsilica was not a natural stone.
The story of rainbow calsilica is curious and fascinating. As far as I know, the people behind its production have never been identified.
Rainbow calsilica is still being manufactured and is used for ornamental purposes, particularly for jewellery.
This large rainbow calsilica cabochon was cut for Stone Mania from a rough piece of stone. At the time, we were still uncertain exactly what it was.
Only the top of the stone has been polished.
