Zircon Crystal with Fluorescent Apatite Inclusions, on Biotite Matrix, Shigar Valley, Pakistan
Beautifully formed zircon crystal, with minor fluorescent apatite inclusions, on biotite and carbonatite matrix.
The apatite fluoresces yellow/orange with 254nm short wave UV light. The carbonatite 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 wave, are in fact either non-filtered, or not the correct wavelength.
Location: Shigar Valley, Gilgit-Baltistan, Pakistan
Size: 60 x 40 x 35 mm. 125 grams.
Measurements are as accurate as possible but due to the nature of some specimens may not be exact.
