JFD202AP5: Superb color and luster. I always really liked the good prehnites from Carchelejo, that's why I have quite a few in the collection; when I saw a particularly good one I always kept it. The good years of that mine were a splendid time.
Oficarsa Quarry, De las Culebras Hill, Carchelejo, Cárcheles, Comarca Sierra Mágina, Jaén, Andalusia  Spain (2004)

Specimen size: 6.1 × 3.3 × 1.5 cm = 2.40” × 1.30” × 0.59”

JFD203AP5: Crystals from this mine are rarely so individualized and rarely are they on such a white matrix. That's why I kept it.
Troya Mine, Mutiloa, Comarca Goyerri, Guipúzcoa / Gipuzkoa, Basque Country (Euskadi)  Spain (±1984)

Specimen size: 4.9 × 4.7 × 3.3 cm = 1.93” × 1.85” × 1.30”

Main crystal size: 1.1 × 0.7 cm = 0.43” × 0.28”

JFD205AP5: Very unusual for San Lino because of its color, much more intense than usual there. Of course, the faces of the hexoctahedron are very characteristic, and even more so considering that when I got this piece, the Emilio and Jaimina mines had not even started working yet.
San Lino Quarry, Aurora vein, Caravia mining area, Cerracín, Prado, Caravia, Comarca Oriente, Principality of Asturias (Asturias)  Spain (±1979)

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.

PTX26AP5: Druse of very sharp Fluorite crystals of good size, between transparent and translucent, soft green in color with yellowish tones and reflections, lustrous, with coatings of small white Calcite crystals. This specimen, of exceptional quality for the locality, also has a curiosity: inclusions of small very intense green 'spots'.
