Description/Interesting Notes:
A fantastic example of crystalline willemite with friedelite crystals from Sterling Hill!!! This specimen hosts a rich showing of
sharp, prismatic crystals of willemite that are coated with rare crystalline friedelite!!! The willemite crystals are present
as gemmy prismatic crystals with razor sharp faces and bright, glassy luster!!! The friedelite crystals are present as
tiny but sharp, submillimeter crystals with translucent pinkish tan color!!! Friedelite is usually seen only as massive material with
crystals being rather scarce!!! The matrix hosts a significant amount of massive willemite as well!!! The willemite
fluoresces a very intense yellow-green under SW UV and also exhibits a very pronounced phosphorescence as well (meaning that it
continues to glow for some time after exposure to SW UV!)!!! 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 OCTOBER 4th!!!
