From the Idar Oberstien area that is famed for its Basalt flow minerals most notably fine Agates. This is a delicate and sharply formed replacment of a flowerlike spray of Glauberite bladed crystals enclosing a vug. All the Glauberite are now replaced by Quartz with the inner part showing a zone of Amethyst fingers. Some fingers show the hollow void where the Glauberite crystals had been. An older specimen ex Ruth Palmer and William Hladysz collections. This is a bit similar to some New Jersey (USA) casts often seen with Prehnite replacing Anhydrite.
Perfect, gemmy and absolutely colorless, this looks just like ice. A natural sculpture of a single etched Beryl crystal, this is also a complete floater. Every surface is complexly faceted, etched and undamaged. Not many minerals can exhibit this degree of sharp sculptural etching, however we see this with Beryl from a few finds and these can be incredible in person. True colorless Beryl (Goshenite) is also quite uncommon. This specimen is displayable from any side or angle, the larger faces are smoothly curved yet striated and it is fully transparent with no inclusions, veils or cracks. Choice gem..

Datolite (color change) and Heulandite
Prospect Park Quarry, Prospect Park, Passaic County
5.1 x 3.2 x 2.8 CM (small cabinet/ large miniature)
Datolite with a strong color change from artificial to daylight, the color goes from a dark olive-green to a yellow-grey. From a remarkable pocket at the classic Prospect Park Quarry locality in 2008, there were not many pieces found. This has contrasting Huelandites with a warm brown color and shows the uncommon color change phenomenon very well. The Datolite is transparent with many faces being very glassy. There is contacting and bruising that can be hidden fairly well by display angle, so not for perfectionists. Overall the condition is equal to the best I have seen from this find, and a cute Northeastern USA oddity.
A single doubly terminated Corundum crystal that shows classic form and habit. This is vividly fluorescent an intense red which is normal for Ruby. The terminations are flat, smooth and have some intersecting lines visible. The crystal faces have typical very rough texture. Strong light penetrates the sides of the crystal showing some degree of translucence. Older specimen (1960's vintage) with nice form and great fluorescence.
Rhodochrosite with Quartz
Wutong Mine, Liubao, Cangwu Co. Wuzoh Pref.
2 x 1.6 x .8 CM (thumbnail)
Small, but very cute, cluster of sharp and slightly-etched Rhodochrosite rhombs. Several faces show complex stepped modifications that add extra pop. Aside from a tiny spray of Quartz crystals, there is no matrix, just Rhodochrosite. This thumbnail from an important find at Wuzoh in 2009, this was one of the last of this form, as most later pockets have more flattened and disk-like crystals. Nice color, form and presentation, if this was larger, it would be a very costly specimen!
A single black octrahedral crystal from vintage 1930's ex. Warren Johansson collection. Dr Johansson was a prolific field collector and active trader well into his nineties. His label is with the specimen. Very nice face modifications and a slight melted look as is classic for the specie. Most Frankinites have considerable damage or are incomplete, but this one is all there, with only minor edge rough spots and one clean contact. Of course this is from the type locality which is really the only source of any sizable crystals worldwide, yet these were at one time plentiful in Franklin. A nice piece that can fit a Thumbnail box but just barely.
Crocoite on Gibbsite
Adelaide Mine Dundas Mineral Field, Zeehan District,West Coast Municipal
9.5 x 6 x 2.6 CM (cabinet)
Slender bright red-orange crystals of Crocoite rise above a contrasting white Gibbsite matrix. A choice specimen with most crystals in good shape, terminated and a few with hoppered form. Minimal damage as is almost inevitable with this sort of fine needles, but most is not visible by naked eye. From a 2014 pocket, this has the color and luster that is most desired, the needles are up to 1.6 CM.
