The bright green color of this mixite specimen is one of a kind! Unfortunately the picture and video don't really live up to this truly bilious green. The whole main face of this specimen is covered with tufted mixite needles. The red-brown matrix adds a nice contrast and holds some mixite at the backside too. Definitely one of the best pieces of this extremely rare mineral we have seen to date!

An absolutely dramatic piece of snow-white pericline on matrix, holding some beautiful adularia crystals of outstanding condition. Out of a find from around ten years ago, this is one of the few very best pieces to be found at this locale. This admirable specimen is naturally broken all around, which gives it an even more impressive character. As a piece of sheer aesthetics, high quality and imposing size this piece is a king among Alpine feldspar specimens.

Small and compact but with a whole lot of compressed beautiful details and great golden sheen. This is a single, hoppered grown gold crystal that appears folded like some origami masterpiece. The shape is distinctly 3-dimensional and perfect all around. This piece definitley lives up to the high reputation of Alta Floresta, where so many high class gold crystals have been found!

One single quartz crystal stands out from a complex matrix of glassy quartz crystals, white adularia and some brown limonite. The main crystal is perfectly flawless and of very good quality. The matrix is mostly unharmed too but right beside the main quartz there is a rough zone which is partly due to contact, partly damaged. A rewarding Alpine specimen if you can live with some imperfection!

Hundreds of thin stibnite needles are exploding in all directions, held together only by sparkling white quartz that fills the gaps and competes with the stibnite in beauty and charm. Herja is well known for its hedgehog type stibnite specimens but this combination with contrasting quartz is a rare sight and stunningly beautiful at that. Watch our video for a better impression of this unusual item!

Three characteristic prase crystals are nicely arranged with some hematite attached to the leftmost crystal. At first glance that crystal might look damaged but in fact that’s just because of the intergrown hematite which caused the growth irregularity. The quartz itself is completely undamaged. The hematite at the very left is a half developed iron rose. But also this is not broken but covered in some iron oxide. It's all natural and fine.

This opal specimen is out of a unique 2014 find that yielded a small number of these rare opal variety. The striking turquoise Paraiba-color is caused by copper and catches the eye instantly. Analysis identified this mineral as the extremely rare tridymite crystobalite opal (Opal-CT).The opal is grown over a shard of glassy smoky quartz. The periphery is broken - quartz as well as opal - but considering the extreme rareness of this material this is unavoidable. A very rewarding specimen from a unique find!

Large and very precisely defined pyrite crystals are beautifully arranged on this heavy specimen. The pyrite shows best golden luster and very nice bevells and striations all over. The larger main crystals are set on a landscape of smaller cubes which makes for an elegant mix. There is no matrix per se, only massive pyrite and smaller crystallized pyrite at the bottom of the specimen. A stunning piece of high quality pyrite in aesthetic composition!
