Gem Tenebrescent Sodalite (w/ Ussingite) from Greenland

11.8.2016

Some pieces of sodalite found in the areas around the Tunuliarfik Fjord are very gemmy, and usually nicely tenebrescent (see animation below).  This piece also has areas of bright green fluorescence which are most likely uranyl activated.  Areas of ussingite are fluorescent green - quite unusual.  Exceptionally bright under longwave (2nd pic).
