Description

The main crystal is 22mm tall! Next to crystal dimensions the most important indicator is this crazy good color. Usually crystals from Peru are so much lighter, but these ones are as close to Nchwaning as they ever could be. Such a dark, intense saturation from Peru is really exceptional, saw not even a fist full of specimen with similar color. And then have a look at the faces, there is a really eye-catching texture on all of them. When you look at my photo you might think that the crystals are cleaved - they are not! I checked each of them with the loup, nothing broken, not contacted, not cleaved - there are modified sharp terminations on each end-point, not cleaved like so many pieces from South Africa. 

And one more detail is of relevance - they are not only on black matrix; they are resting on sparkling, razor sharp and water-clear Quartz crystals. The contrast - black manganese matrix, light rock crystals and pigeon-blood red Rhodochrosite crystals, that is really amazing. The crystals don´t have the luster and clarity of N´chwaning, but for Peru this is really incredible! And aesthetics, contrast and color are wonderful.
