JFD210AP5: Like a feather, this 'stalactitic' growth of Vanadinite crystals rises gracefully, forming a special piece.
So many vanadinites, but from time to time one still surprises us...
Mibladen (Mibladen mining district), Midelt, Midelt Province, Drâa-Tafilalet Region  Morocco (±2002)

Specimen size: 7.2 × 6.3 × 4.2 cm = 2.83” × 2.48” × 1.65”

JFD211AP5: Always in search of something different, this piece moved me because it is so different from the usual in Mefis, which yields very large crystals, even enormous ones, but, although they can be sharp, they always tend to be somewhat 'rough'. Finding something elegant and delicate from there, like this group of crystals, is really rare.
Mefis, Taouz, Er Rachidia Province, Drâa-Tafilalet Region  Morocco (04/2014)

Specimen size: 10.8 × 10 × 4.2 cm = 4.25” × 3.94” × 1.65”
