RH02-35 - Hematite (pseudocubic) - $ 600
Ouro Preto, Minas Gerais, Brazil

Hematite (pseudocubic) from Ouro Preto, Minas Gerais, Brazil [db_pics/pics/rh02-35a.jpg]

Complexly terminated crystals of hematite to 2.6cm on a massive hematite matrix. The crystals have incredible mirror luster and are sharply formed, pseudocubic in fact. Some twinning appears to have occurred to some of the crystals. Nice display angle for the piece adds to the pizzazz. Minor edge wear is present on a few crystals but for the most part the crystals are in very good condition.

I LOVE THESE THINGS! WHAT A NEAT EXAMPLE OF INTERESTING MINERALOGY, having talc replace a hard mineral like quartz !?!This is an incredibly rare pseudomorph of talc after quartz on massive talc from Germany. These pseudomorphs are quite old, having come out of the ground prior to the 1930s. Unique to this location, the crystals are very sharp and have a soft vitreous luster. One of the hardest pseudomorphs to find in any condition and this piece is nearly perfect, AND OF LARGE SIZE. As you can imagine, this is a "must have" for any pseudomorph collector. Ex. P. Pohndorf collection (1931). E. Mitchell Gunnell and Hauck labels included with piece.

This is a rare hydroxyl, of potassium, iron, sulfate, usually found in arid environments, such as Goldfield. In this case, we have a sparkling, druse, of reddish-brown, crystals on a pitted, vuggy, matrix.


RH3-39 - Arsenopyrite pseudo after Pyrrhotite - $ 900

The combination of arsenopyrite after pyrrhotite is definitely not one of the more common examples of pseudomorphism. In this specimen, the crystallographic outline of pyrrhotite is clearly visible as well as its luster. However, the mineral has changed from one to the other. this is a classic but very rare pseudo, and this particular piece is exquisitely formed and for what it is, about as aesthetic as you can ask for!


RH1-65 - bipyramidal Wulfenite - $ 950
Ahumada Mine, Los Lamentos, Chihuaha, Mexico

bipyramidal Wulfenite from Ahumada Mine, Los Lamentos, Chihuaha, Mexico [db_pics/pics/rh1-65b.jpg]

Of all the wulfenite habits extant in Los Lamentos specimens, the rarest is the bi-pyramidal habit exhibited by this fine piece. Crystals to 1.0 cm abound on a limonite matrix. The lustrous crystals terminate in a caramel candy, orange-brown color. Aesthetic and important!


RH1-66 - Azurite - $ 600

Azurite from Chessy, France [db_pics/pics/rh1-66b.jpg]

Lustrous, deep blue, azurite crystals are intergrown into a large rosette. Even neon blue highlights sparkle occasionly from this specimen. It is also a near floater. "Chessylite" in this size and quality is hard to come by today and most is 100 years old or more!

This venerable old poly-metallic deposit, especially famous for its mimetite specimens, has also produced this fine, delicate, spinel twinned, silvers. This is a super, rather large example of the classic habit from the mine, and a beautiful spire of crystals shooting off of a centrla spinel twin.


RH3-34 - Malachite - $ 1250

This is an exciting piece - a very rare old 18th or early 19th century specimen of classic elongated fibrous malachite crystals, from the noted old German district that produced the best malachites of the day besides Russia. It is relatively aesthetic, and has crystals to 1 inch, which is of very good size. I have sene only a handful of specimens of ANY quality on the market, of this classic style and from this locality

This specimen once was a rosette of intergrown, bladed, azurite crystals which have been totally pseudomorphed by copper. The specimen exhibits a very nice old patina. These complete floaters are quite rare today, and were found in the 1940s through 1950s I am told. They show a remarkable complete replacement of azurite by copper, and are to my knowledge unique in their aspect, form, and size compared to other azurite pseudomorphs

A druse of vivid, bright green, spherules, of pseudomalachite, covers the nooks and crannies of brown, blocky, limonite. This green color is more intense than that of malachite. One is a phosphate, the other carbonate....don't confuse the rare with the common!

Nice cluster of blocky crystals of malachite after azurite from a rarely seen location in South Australia. The 3.8cm cluster consists of malachite crystals which have a modeled green color, a chatoyant luster, and are about 1 cm across. Blades of azurite which have not been completely replaced by the malachite can also be observed on the cluster. Great location piece!

This is a large, heavy, long prismatic, lustrous but opaque, crystal cluster, combining two elements much in demand for making vital, metallic alloys. The color is blackish-brown, and the specimen is in very good shape, quite aesthetic overall.

Colored red by cuprite and green by malachite, this aesthetic copper specimen is extremely well crystallized. The largest copper crystal measures 4.0 cm in length. But the highlight of this specimen is the incredible, spear like, crystal, exhibiting elongated, possible tetrahexahedral twinning. This is a fine old Michigan specimen.


RH02-55 - Prehnite pseudo after Anhydrite "snakehead" - $ 600

Prehnite pseudo after Anhydrite

An American classic, a pseudomorph of prenite after anhydrite from the Patterson, New Jersey . These light green crystals are a "must have" for any pseudomorph collector. This piece is a single crystal which has been hollowed out during replacement. The crystal is slightly contacted along the back of the piece but no other damage is present and it is very 3-dimensional and aesthetic. Another great Hauck piece both old and beautiful!

This mineral species, a rare silver bromide, reaches its zenith here at the Broken Hill Mine, NSW, Australia. Elongated, lustrous, translucent, green, crystals of bromargyrite to .7 cm in length, sit up on matrix. In some ways the bromargyrite crystals look like jelly beans. Classic and beautiful for this material!
