Happy Holidays! Christmas Calcite from the Sterling Mine, Sterling Hill, New Jersey

27.9.2016

This is a classic specimen of "Christmas Calcite" from the Sterling Mine, Sterling Hill, Ogdensburg, New Jersey.  This material contains brightly fluorescent willemite and calcite, with non-fluorescent franklinite and zincite.  Under short wave UV, the willemite shows a bright green response and the calcite fluoresces bright red.  Perfect for getting you into the holiday spirit!  This specimen shows an interesting multi-wave response, as it is also fluorescent under long wave UV, with the willemite showing a more subdued green fluorescence, and the calcite glows magenta/pink.  The size of this piece is 7.6 x 7.6 x 3.8 cm, and it weighs 428 grams.
