Thank you for sharing.

Carles,

for sure i haven't seen as many fluorapatites as John in my life - but this one is really among the finest! A truly superb piece of art created by mother nature :-)

Congratulations!
Tobi

Roger and Tobi,

Very grateful too for your nice but (IMHO) exaggerated comments. The photo was shot by Scovil, not by me, and as everybody knows he is a master of perfection.

Of course, Jeff Scovil’s photo of is excellent, as usual. This is especially the exceptional character of this specimen I said.

Helvite, genthelvite, calcite, quartz, magnetite

From the vendor's description: Group of very sharp tetrahedral helvite crystals with a superficial layer of genthelvite. It is on matrix, with white calcite rhombohedrons, dodecahedral magnetite and parallel growths of quartz. Very aesthetic because of the contrast between the salmon helvite-genthelvite and the calcite and quartz matrix. Specimen size: 75 mm × 52 mm × 37 mm. Main crystal size: 15 mm × 13 mm. Collected in 2012.

Huanggang Mine, Kèshíkèténg Qí, Chifeng, Inner Mongolia A.R., China.
