An incredible Yindu Fluorite with a glass-clear blue crystal that has a deep purple cloud inside and a fine edge phantom as well. Super sharp and resting on Calcite the Fluorite has impeccable bright luster. The overall effect is like looking into an aquarium. Good Yindu Fluorites are now very much admired and sought after, as they are both beautiful and unlike most any other Fluorite. One edge of this elongated cube is contacted where it was on matrix but there is no damage, breaks or chips. This rests on a crystalized mass of white Calcite and the contrast is excellent. Better in person too.
