Daylight fluorescing Electric opal from Zacatecas, Mexico

Natural color changing opal that goes from light yellow/colorless in indoor lighting to electric green when exposed to natural sunlight. One of the few minerals to fluoresce so strongly in natural sunlight. It has proven to be an exceptional mineral for gemstone enthusiasts and mineral collectors alike. We are lucky to be providers to the market. 
Unfortunately supply is very limited, mining has stopped. Facet rough is extremely rare but we have ample specimens of all sizes. We are only taking wholesale orders for this material at the moment. For more information please contact us.
