"With consumer and buyer protection in mind, the AGTA will now require its members who sell or consign any red andesine-labradorite to disclose it as diffused material, and indicate this either in plain language or by use of the industry accepted code, āUā, for diffusion*. If it can be determined that the material is natural, as in the case of particular Oregon material; then it may be disclosed as untreated" -AGTA Email/Article
All That Glitters only has the Natural Oregon material. The gemstone that currently is available was found in Oregon by the owner of All That Glitters after days of digging in adverse conditions. It was faceted by our master cutter, who has won an award in the most recent AGTA Cutting Competition. He has won awards and recognition in past competitions also. This Natural Oregun Sunstone is currently scheduled to appear in a book dedicated to gemstones - to be published later this year. This is your chance to own not only a gemstone that has a great color, is of natural U.S. origin, contains desireable copper schiller, perfect facet junctions, proper angles which produce brilliance, a VERY high 100,000 diamond polish, faceted by a master cutter - this gemstone should be appearing in a book that will be distributed and viewed around the world. You can be the new owner!
