Thanks Carles, the specimen really features a nice combination of two sulfide minerals, both in really good condition. And the specimen is actually even better and has a better contrast, but it was a struggle to capture both the matt-finished galenas and the high-gloss sphalerites on a photo ... and there are also tiny, sparkling red sphalerites on the specimen, unfortunately the photo didn't capture them :-(
I made an interesting discovery concerning the two sulfides on the specimen, a special topic will follow later ...

Very nice and aesthetic, both Swiss smoky quartz specimens. These kind of pieces are very much appreciated by the collectors of alpine minerals.

Aesthetic specimen. Nice color contrast. I guess it's better in person and am sure you might improve that photo (with a bit of patience, of course). I know how difficult is sometimes to shoot these transparent colorless quartz crystals.

Have you tried a darker background for your beautiful Dalnegorsk calcite?
