Rainbow Calsilica Pendant
Rainbow Calsilica is Not Fordite
A slightly larger and chunkier rainbow calsilica pendant crafted by hand in an elegant sterling silver setting. Despite its size this stone pendant is surprisingly light weight.
This distinctive gemstone is a man-made material first introduced the world in 2002 at the Tucson Gem and Mineral show in Arizona. Although initially presented as a natural stone from Mexico, scientific analysis soon confirmed that it was in fact man-made.
Rainbow calsilica is believed to be made up of crushed calcium carbonate which is commonly found in rocks as the minerals calcite and aragonite. It's been artificially coloured using distinctive blue and greenish yellow pigments and plastic-like stabilizers were also identified which include traces of a paraffin derivative. An incredible amount of effort had gone into to creating a stone that could be passed off as a natural material and traces of the minerals hematite, celestine and calcite were also found.
The argument about whether rainbow calsilica was a natural stone or not lingered for a few years during which time its popularity increased. Little has ever been discovered about its true origins or the people behind its production and we continue to hear stories from customers who have been told it's definitely a natural rock from Mexico.
Rainbow calsilica is sometimes incorrectly described as Fordite but the two materials have very little in common.
A unique and colourful stone pendant with a great story behind it.
