WELL POLISHED FIRE AGATE STONE
This is a stone where we have just polished it to expose the natural fire agate pattern under the Chalcedony layer. We also have the rough in our sister store QUALITY ROUGH..
This stone was mined in Mexico but it is found in Arizona also.The stone appears to glow inside like opal.The gem is thought to be formed when hot water saturated with silica and lava oxide invade cavities in the rock and cool. Chalcedony with iron oxide begin to grow on the surface.The iron oxide gives the basic brown colour to the stone.It grows layers of silica and iron oxide. These alternating silica and iron oxide cause the brilliant fire from the stone.After the iron oxide ran out of the specimen colourless chalcedony contained to grow over it.
The Gemstone Sheriff program allows our members to request an audit on any auction, which is completed by an independent Gemologist who assesses the accuracy of the item description and pictures.
