Hagendorfite is a rare iron phosphate, and I personally have never seen one. However, this is an old piece purchased from David New's famous old mail order species lists, in 1976. Although small, it seems rich and well-crystallized with sharp clusters of xls to 4mm. There is a hint of green-brown color, in person.

JWHITE-77 - Villiaumite - SOLD

Villiaumite from Bortolan quarry, Po�os de Caldas, Minas Gerais, Southeast Region, Brazil [db_pics/new09/sea77b.jpg]

Rare, discrete microcrystals of villiaumite, from an old find in Brazil. John White purchased this from Carlos Barbosa in 1978 for $30. Such discrete (if small) crystals are extremely rare, both for the species and for Brazil as a source of it, and I believe this was a one-time find.

JWHITE-76 - Spangolite on Barite - SOLD
Mex-Tex Mine, Bingham, Hansonburg District, Socorro Co., New Mexico, USA

Spangolite is one of the most rare and desirable copper species, a brilliant blue in color. Although very rare worldwide, some small cavities such as this are found in the fluorite mines of Bingham, New Mexico, on occasion. I personally think this a bizarre association, considering Bisbee is hardly a fluorite mine and there you get the best crystals. Although smaller, these, in association with barite, are just as beautiful , though! This piece is rich with several vugs of microcrystallline spangolite.

JWHITE-75 - Olivenite - SOLD

SUPERB sharp and large crystals for the locality to 3-4 mm in size. This is a very exceptional quality for Nevada olivenite, on a displayable miniature-sized specimen.

A very attractive "pocket" specimen of ferrierite from this type locality. Ferrierite is a rare zeolite species Named for Walter Frederick Ferrier (1865-1950), Canadian geologist and mining engineer.(MINDAT)

Unusual, elongated, robust crystals of hollandite in frozen quartz matrix. Very odd , for the species. I had not seen crystals in this style before

JWHITE-71 - Arfvedsonite (Manganoan) var. Juddite on Braunite - SOLD
Tirodi Mine, Tirodi, Madhya Pradesh, India

I had never heard of Juddite before but was surprised to see a reddish mineral from India, associated with braunite, and so assumed it to be a manganese species. It turns out that it is indeed the manganese variety of arfvedsonite, by modern classification. the crystals are bright red, small but beautiful under a scope. The matrix is braunite: Braunite is very rare, and these are old specimens, from India. according to MINDAT: Juddite was named by Lewis Leigh Fermor in 1908 in honor of John Wesley Judd [February 18, 1840 � March 3, 1916]. Judd was a field geologist and petrologist for the British Geological Survey and later professor of geology at the Imperial (Royal) College in London, England.

Bavenite is a rare silicate, and this specimen is composed of almost solid bavenite in opaque, radiating sprays that interlock. They have a vitreous lustre to them.

According to MINDAT, "This mineral, fully hydrated copper sulphate, is very rare. " This is a LARGE specimen smothered in crystallized boothite, composed of stacks and sprays of agglomerated microcrystals. It is also very attractive as a display specimen. I have never had another example of this species for sale. Acquired by John White in 1969

JWHITE-67 - Chloanthite (Ni-Skutterudite) - SOLD

A very heavy specimen of solid skutterudite, from a CLASSIC and important locality for the species! These are old specimens, some to the 1800s, and now rare on the market. Technically this former species is now regarded as an arsenic-deficient variety of Nickel-Skutterudite or simply as a synonym for Nickel-Skutterudite.. In any case, this is an excellent example of the nickel species, well crystallized, and a beautiful display quality miniature. The complex form of these crystals, and their bright lustre, mark them as German apart from modern finds in Morocco.

JWHITE-66 - Digenite - SOLD

This is a huge single crystal of digenite, one of the more rare copper sulfides in crystalline form. Butte was known for these, 50 years ago, but crystals of this calibre and size are now hard to come by. It has a wonderful form, and a classic dull matte lustre (distinct from chalcocite from this locality). Overal, it displays fairly dramatically, surprising for a "black ugly"

JWHITE-63 - Descloizite - Cuprian - SOLD

A historic old classic, featuring a beautiful sparkling malachite vug set within the thick, heavy malachite which was so prized by Russian lapidary carvers in the 1700s and 1800s. The drusy malachite forming ballshaped clusters within the seam, is very bright, subtly different from African material. Now, these locales are long gone, and Russian malachite is still prized by specimen collectors. An old parchment label is glued to the back of this specimen. From the Scott Williams collection.

A hefty chunk of manganite ore, with a lable noting "near Laramie, Wyoming" which I found must surprising. No locale for manganite in Wyoming is listed on Mindat, but that does not mean it is impossible and so I took a gamble and bought it. Maybe others cna place it more precisely?
