Description/Interesting Notes:
An incredible, old time example of this rare species from Germany!!! Along with cumengeite, I find these classic
whewellite crystals to be among the most crystallographically impressive in the mineral kingdom!!! These complex, shield-shaped crystals literally
look like faceted gems!!! This is a choice, text-book perfect crystal of whewellite!!! The crystal has pristine, razor-sharp faces and gem clarity!!!
The crystal is undamaged and complete all around (note that the small protrusion on one edge is a natural modification!)!!! In person, the crystal has dramatic and intense play of light within!!!
The crystal is twinned and the twin plane is clearly visible upon close inspection!!! The crystal has an incredible number of sharp, complex modifications and
faces that make it simply amazing to study in person!!! This is an outstanding example of this rare species!!! Inerestingly, this crystallographic
marvel was named after English naturalist William Whewell, who invented the system of crystallographic indexing!!! Also, this is one of the
relatively few organic mineral species and this is the same mineral that is responsible for most kidney stones (and also what makes the leaves of rhubarb poisonous!)!!!
This is truly an incredible and fascinating mineral species indeed!!! This is an old time specimen and retains an antique glass vial and an
old label from the Freiberg Academy!!!
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 SATURDAY NIGHT FOR A SPECIAL 5-DAY AUCTION, ENDING THURSDAY NOVEMBER 10th!!!
