Quartz with Pyrite
Dalnegorsk, Kavalerovo Mining District
Primorsky Kray, Far Eastern Region,
9.3 x 6.8 x 4.1 CM (cabinet)
Late Summer 2018
A very esthetic specimen ex Charles Noll collection. This is a bit of a mystery, The labels attribute this to Dalngorsk and the dusting of Pyrite looks just like some tiny pyrite found there on white Calcite, but this is on Milky Quartz in doubly terminated prisms. I can not find any other examples with this look, so we have tried to confirm the locality. I have been told this was probably from one of the very first waves of specimens to come from Russia which had many oddities not seen again. This fits with the collection vintage, and would make this a very special addition to any fine Dalngorsk suite. The quartz are doubly terminated, perfect all around and are epitaxially coated with tiny Pyrite crystals. An attractive arrangement and striking specimen unlike anything we have seen from any locale worldwide.
A brazillian specimen that was mined over 25 years ago. Very sharp, glassy twinned Sphenes on matrix up to 2.5 CM on matrix. The matrix is also covered on both sides with a druse of micro Titanite crystals that sparkle nicely. Some of the tiny Titanites seem to be untwinned which is rather rare but is known in a few specimens from this locale. The main crystals are well exposed from the matrix and show well from several angles. Some damage and contacts can be found on close exam but these do no stand out. The price reflects this, a good value for a very displayable specimen.

Chah Milleh Mine, Anarak Dist., Nain Co.
4.2 x 3.2 x 2 CM (miniature)
Late Summer 2018
Botryoidal Mimetite with fine color and form. From finds in 2014 at the ancient mine of Chah Milleh, this piece has minimal matrix. The shapes of the Mimetite show the forms of a previous generation of Wulfenite, thus these are either a pseudomorph or epimorph. Either way this is an attractive miniature in fine condition from this significant Iranian locality.
A cluster of Prehnite crystals are almost completely covered with tiny colorless and white Grossular crystals. There are a few small areas of uncovered Prehnite where it can be seen that these are glassy and transparent. Colorless or white Garnet is very rare and the tiny Grossular here are nearly all transparent, mostly colorless with a few white translucent crystals. It is impossible to find this combination available unless from an oldcollections being dispursed.
A fine thumbnail of blue anatase from the classic locality of Hardangervidda. In excellent condition this has excellent luster and the Anatase are well exposed from the Quartz. Looks nice from several angles, a small but attractive Anatase with a good deep blue hue.
Rhodochrosite -rhombic and etched forms
Wutong Mine, Liubao, Cangwu Co. Wuzoh Pref.
3 x 2.3 x 2.3 CM (small miniature/ large thumbnail (toenail))
Late Summer 2018
Deep red color, translucent to transparent and with fine form, a choice toenail sized Rhodo. From the Wuton (Wudong) mine that is no longer producing, but at one time this discovery made nice Rhodos much more affordable for many collectors. This piece has a pair of modified rhombs joined in a V shape. One is sharp and glassy with some stepped etching, the other is more heavily modified, etched and recrystallized. This is the style that was often compared to Rhodos from Sweet Home. There is a lot of similarity but the price is very much lower from this locale!
A small thumbnail showing intense green core clear Grossular crystals. This habit was often called "frog egg" and was only found at the Jeffrey Mine, and only rarely. Ex Larry White collection, he obtained this in 1975, at that time it was labeled as a Uvarovite, a common error when these were first found. This specimen has super sharp, gemmy crystals with a small bit of matrix. The luster is bright glassy, transparent and is over all in fine condition. Looks especially great under magnification where small details can pop out. These have become very hard to get and it seems there will never be more. Small but very eye catching.
Prehnite -elongated crystals
Jeffrey Mine, Asbestos
3.9 x 3 x 1.8 CM (small miniature/ large thumbnail (toenail))
Late Summer 2018
The amazing Prehnite crystals from Jeffrey mine took many forms and habits, unlike anything ever seen elsewhere. Although Prehnite is not really a scarce mineral, sizable prismatic Prehnite crystals are incredibly rare. This prismatic Prehnite cluster is a good example, sharp, with some complete doubly terminated crystals to 3.8 CM long. The luster is pearly and the crystal tips are transparent, the body is more milky translucent. There is chipping only on the outer edges, the center area is pristine and undamaged. A good small miniature showing an elongated habit, wide center sections and with square cross section terminations.
