Description/Interesting Notes:
A terrific example of tugtupite from Greenland!!! This specimen hosts a rich showing of red tugtupite in
association with black crystals of aegirine and other unidentified species!!! The tugtupite has
fantastic color and areas of marked translucence!!! Upon close inspection with a loupe or scope one can even see
some minute crystalline features in areas!!! The tugtupite fluoresces a bright red
orange under SW UV and there are areas of green fluorescence as well (an unidentified species)!!! In addition to the
fluorescence, the tugtupite exhibits pronounced tenebrescence (pink-magenta to deep cherry red) as well - meaning that
the tugtupite shows a significant darkening of color after exposure to UV that gradually reverts back to the original
color over a period of time!!! Rare material!!!
The pics hardly do it justice!!! Must be seen in person to be fully appreciated!!!
Good luck and be sure to check out my other exciting mineral auctions on ebay!!! STAY TUNED!!! MORE AUCTIONS WILL BE ADDED MONDAY NIGHT FOR A SPECIAL 3-DAY AUCTION, ENDING THURSDAY SEPTEMBER 13th!!!
