This is a large, high-grade heat treated amethyst “citrine” crystal cluster or geode. The process involves heating amethyst geodes or clusters to high temperatures, which transforms the iron concentration within the quartz structure to achieve the desired golden to deep orange color. This heat-treated material is often sold commercially as "citrine". 17” H x 17” W
