GYPSUM VAR. SELENITE " DUCKBILL " DOUBLE

“ OLD STOCK “ HIGHLY FLUORESCENT/ PHOSPHORESCENT GYPSUM VAR. SELENITE FROM THE RED RIVER FLOODWAY AREA OUT OF WINNIPEG, MANITOBA, CANADA. THIS AWESOME “ DUCK BILL “ STYLE HAS AN ADDED FEATURE OF ANOTHER GYPSUM BALL JOINED IN THE BACK. THIS IS UNCOMMON FOR THE FIND. WHAT’S EVEN BETTER IS THE PENETRATING CRYSTAL THAT SITS TO THE SIDE OF THE MAIN CRYSTAL.

ACCORDING TO MINDAT- THE FORMATION IS DUE TO TWO GENERATIONS OF GROWTH. THE FIRST GROWTH FORMED NEAR-SPHERICAL ROSETTES OF STOUT INTERGROWN CRYSTALS. THE SECOND GENERATION, THE ONE THAT MADE THEM FAMOUS, GREW IN LARGE GOLDEN CRYSTALS WITH A UNIQUE TWINNING SHAPE THAT RESEMBLED A DUCK’S BILL. SOME RARE EXAMPLES HAVE TWO ROSETTES CONJOINED IN STRIKING FORMATIONS. -
