Zircon Crystals with Fluorescent Apatite Inclusions, Biotite-Calcite Aegirine matrix, Astore Valley, Pakistan Bent crystals The physical properties of GobiBeautiful red zircon crystals, with fluorescent apatite inclusions in biotite aegrine calcite matrix. The apatite fluoresces yellow orange with 254nm short wave UV light. The calcite in the biotite calcite matrix fluoresces pink under 254nm short wave UV. PLEASE NOTE: This specimen only fluoresces with 254nm, short wave ultraviolet light. A filtered, high quality lamp is ESSENTIAL. Most multi function, inexpensive UV lights, that claim to be short
