Natural occurring blend of Citrine and Amethyst in the same crystal! Varied texture and interesting growth features make up the crystal’s surfaces. This one is a pretty even split between the Amethyst and the Citrine, both equally dispersed throughout the piece. Natural Ametrine has been found in only two locations; Siberia, and Bolivia. In some instances, other material has been created synthetically as well for gem rough. This one is best as a fine display piece… Better in person as well! 100% natural!
