Rainbow Calsilica is a relatively rare new stone from Mexico. It first came into the market in 2002. There is some controversy concerning whether these beautiful colors and banding are all truly natural. See http://snipurl.com/de7c , article in Professional Jeweler http://snipurl.com/dek7 for more information. However, it seems that this doesn't stop people from loving this stone! Even Stephen Dweck used this stone in his 2003 collection (or so we are told). The stones are stabilized using the same process used for Turquoise stabilization. I currently do not have any information concerning fading for this stone but will update as soon as I get more information.
