Euxenite Value, Price, and Jewelry Information


Euxenite is seldom seen in collections. Most collectors would not regard the mineral as facetable, but transparent fragments and areas of crystals have been noted that could cut small gems. Sometimes cabochons are cut by collectors, but these are not very striking. The colors of faceted stones would be too dark to make them appealing.
