A super esthetic older piece from finds made more than 50 years ago (predating the famed Lees pocket). This is in flawless condition the cluster of Barites has fine steel blue color and contrasts with a yellowish Calcite matrix. In addition to the nice arrangement some of the Barite faces show a very unusual etching pattern seen in some photos here. Lots of visual impact for the size, the color is a bit richer than the more recent finds, all in all far better than "above average", an excellent old time Colorado specimen.
Dioptase very large crystal
3.1 x 1.3 x 1.2 CM (small miniature/ large thumbnail (toenail))
A fine large single prism composed of two main parallel crystals that are joining in a single shared termination. Super lustrous with brilliant color, in fine overall condition. The base has a few tiny adhering crystals that are not complete and it is possible to see the break where this was removed from the host mass of Dioptase where this grew. Aside from the matrix the main large crystal is in perfect undamaged condition. From finds a few years ago in the Kaokoveld, large prisms like this were just not known from other locations. A choice example of this find
Stefanie Mine, Bad Blieburg, Gailitaier Alpen and Karnish Alpen
9.3 x 6.8 x 5.4 CM (cabinet)
A very well crystalized Wulfenite from the area of the original discovery of the specie (Bad Blieburg). The area mining began in the 1500s and was extensive, producing a wide variety of habits and occasionally some extraordinary pieces. The Stefanie mine was the last to close and quite famous as a productive locale. This piece is well above average, the crystals to over 1.3 CM and most show sharp edge and or corner modifications. In fine condition overall, however a very close inspection can find some tiny edge bruises that are not really noticeable in normal display. The color and luster are excellent and stronger in person. A choice older specimen.
A large block of matrix with sizable surfaces densley covered with interesting Phosphates, mostly Strengite balls and Leucophosphite but others are also present. From the remarkable mine at Teskov that has been a fine source of Phosphates. Ex. Dr. Petra Choce collection, this could be turned into many thumbnails or micro specimens but as is it offers many esthetic views under magnification.
Wulfenite with Mimetite
San Carlos Mine, Municipio de Maunuel Benavidas
4.7 x 3.3 x 3.2 CM (miniature)
Gem clear, sharp and glassy bright red Wulfenite from the new find (2017-18) at the San Carlos Mine. The Wulfenites are associated with small balls of Mimetite that are both yellow and Orange in color. The large main crystal is 1.5 CM diagonal and sits perfectly on the matrix. Some bits of adhering matrix and tiny contacts are noted but not significant, and there is no chipping or damage on any of the main crystals. The Wulfenites at San Carlos were mostly yellow and orange but a few reds were found, this is in person a super intense red color as fine as any top Red Cloud Wulfenite. The crystals are unusually transparent and have brilliant luster on the faces. Better in person.
A single, sharp terminated crystal of Epidote. At this locale these are often found to be zoned with Clinozoisite but usually not more than 50% hence the Epidote label. From the long closed now classic locale of the VAG mine in Northern Vermont, USA. A fine clean translucent to transparent crystal in fine shape from the Rodingite zone famed for world class Garnets. Lustrous, undamaged and with distinctive striations, a choice little classic Northeastern US piece.
Tarbuttite and Pyromorphite
Kabwe Mine (Broken Hill Mine) Kabwe
6.5 x 3.1 x 2.4 CM (cabinet)
Two habits of Tarbuttite crystals are contrasted by distinctive green Pyromorphites. An unusual combination of species, I have not seen these together before. The Tarbuttite is very sharp and in distinct crystals, the Pyromorphite has the unusual habit of pointed pinacoid terminations (many are doubly terminated) and are color zoned with a transparent area in the center. This locality (Kabwe) was known as the Broken Hill mine of Northern Rhodesia, from 1906 until 1964. This is an older specimen.
These Hematite pseudos when they are good have an incredible form. This specimen is one of the very best I have seen, perfect, complete all around and with well developed faces. Marcasite is an unstable mineral that can decay over time but these pseudos are perfectly stable. The detail of growth is perfectly preserved and presented on all the faces and the form looks like a leaf. These are sporadically available but very few are of this size and sharp development. A superb pseudomorph and an very esthetic piece.
