Scalenohedral DogTooth Calcite on Blue Purple Fluorite Matrix, UV Reactive, Fluorescent citrine Multiple highly lustrousClear yellow and translucent scalenohedral dog tooth calcite crystals sit atop blue purple fluorite matrix. The calcite fluoresces a light orange and the fluorite a deep blue under long wave UV light. You will need a filtered, 365nm long wave UV light to see the best results. A black light will not work well on these specimens. We carry a quality long wave light that is affordable. From Balochistan, Pakistan Size 67 x 55 x 40 mm. 96 grams.
