  • This is an interesting one! The main part of the specimen is very prominent lollingite botryoids that are totally covered with lustrous, well-formed crystals of arsenopyrite and some skutteruditer. This is a significant piece! Displays very well.

  • Most of what you can see on the front of this specimen is a concave area of sparkling arsenopyrite crystals. The crystals cover botryoidal safflorite that is naturally fractured in vertical cracks. The calcite has been removed from this specimen to reveal the unique structure. Displays exceedingly well!

  • Cobalt

  • Just a big chunk of, I believe, arsenopyrite, possibly lollingite wit ha more generous smattering of chlorite flakes embedded in it. It comes with antique label denoting it is glaucodot with native arsenic, etc. I don't think so. It is a nice old-time piece though!

  • A very heavy, dense plate of botryoidal safflorite. The safflorite is present as fine grained botryoids and as botryoids that have imprints of calcite crystals. Excellent!

  • Discrete mineral phases of the various minerals can often be difficult to observe. Many of the arsenide minerals occur, mostly, in mixtures of minerals, often too intimate to analyse or observe. This specimen has excellent differentiation of two phases and includes nickeline, mostly at the core of the lobular growths and lighter, more silvery, rammelsbergite on the outer rims of the growths. They have been analysed. This one is cut and polished on one side just sawn on the other side.
