I have never seen a copper quite like this in person, though they are referenced in pre-1970s finds here (see ROCKS & MINERALS vol 81 #4, page 266 for example). These copper crystals somehow extended during growth to fill spaces in amygdaloid deposits, and form these strange "pipes".
An old Bisbee copper with branching form, completely crystallized from top to bottom with sharp spinel twins. Elegant overall form! This is a fine example of native copper for this important old US locality.

Talk about elegant coppers! This exquisitely crystallized specimen is as good a piece a syou could ask, for ht locale!
ex. Martin Lewadny
Delicate and elegant Copper consisting of very fine dendritic crystals. The dendrites range from 1-2 cm, and the crystal growth on each one is very sharp and intiricate. The excellent patina adds nicely to the overall aesthetics of this piece, which is from one of the world’s classic copper localities.

Excellent well-defined single spinel twin crystal of Copper that is an amazing 6.7 cm long. The modified Copper cubes growing the length of the specimen are attractive and sharp, and the copper has an excellent patina. Spinel twin Coppers this long are far and few between from African locales. This old copper specimen is from the Stan Korowski collection who originally brought out many of the famous Zambian minerals and wrote about them extensively in the Min. Rec and other journals years ago.

Lovely and quite sculptural arborescent growth of Copper crystals. The branching is quite balanced, and there is even a three-dimensionality to it that is very rarely seen. The patina is excellent, and a few of the copper crystals near the base reach close to 1 cm. An exceptional copper for Nevada, in particular!
ex. Francis and Patricia Benjamin
The pics say it all! this is a fantastically complex and intricate copper, from most likely the late 1800s, with 3-dimensionality and aesthetics that are hard to beat.
A very sharp, dramatic, arborescent specimen of elegant copper crystals in herringbone form, reaching up from a well trimmed matrix. Excellent display piece for an unusual habit ! If we knew the mine name for sure, it would be much more valuable, as well, so for display purposes it is a bargain in that sense - as with many such specimens the mine names have been lost with time.

A truly stereotypical example of the classic "blister ore" that miners loved even more than the finer crysatllized minerals of the day. Why not...its really neat and attractive!? However, because they were not valued so highly at the time by more prominent colelctors, few have been preserved in good shape. this is excellent for the size because of its lustre, color, 3-dimensionality, and aesthetic quality.

What the heck is this?! It is a VERY FINE, large, uncommonly good example of the kind of sculpture made by miners in the late 1800s and early 1900s to while the time away between shifts or on breaks, and in fact the skill of carving these "flowers" with dull metal chisels was a highly refined and competitive art form. I have seen a number over the years of SINGLES. but for somebody to create a group like this without it coming apart, as they chisel the solid copper mass, requires incredible skill. I have not seen better for sale and my friends who know more tell me that this really is one of the best examples surviving. The Seaman Musuem has a bigger, but different one. This one is not only good for the number of feathers and size, but also for the fact that it was done in a precise manner to make it as elegant as possible. Usually the chisel carvings are one-directional, not 3-dimensional as this one. Traditionally, these sell among collectors of mining ephemera for $1000 per feather, in clusters. Most clusters are only 2-4 feathers, of course, so that makes them affordable. This has NINE good feathers, and so is worth $9000 as these go (I am told). I can tell you that for the money, you get a lot of impact from the public and even most knowledgeable collectors thinking this is natural, because of its elegance. Anyways, its not made in the ground but it IS nevertheless a ahighly significant Michigan mining artifact, that fits in well with a fine mineral collection of coppers. Comes with custom lucite display base.
9.6 x 7.9 x 5.0 cm. How many malachite pseudos have we seen from Tsumeb? Hundreds? Thousands? And almost all after Azurite, too. This one features malachite of velvety nature having completely replaced intricate fans of crystallized copper. It has superb aesthetics, and is even complete on both sides. At one time this was in the Marshall and Charlotte Sussman Collection. Ed David obtained it from Stuart Wilensky in 1998. Ed always felt this to be a littl emore unique than other Tsumeb malachites he had owned over the years. If in doubt that it was from Tsumeb at all,the wulfenites prove the point.
This is one of the largest AND most dramatic coppers i have ever seen in museums or private collections for this style - a style so characteristic of this mine that it is immediately identifiable to a single mine in a manner so few Michigan coppers are. The intricate networking of the copper crystals is mesmerizing. I have always loved this piece for the dramatic spiral of the major central spinel twin, which curls up through the specimen with other crystals around it and is then cradled at the top in a nest of intricately crystallized smaller copper crystals. That central spinel twin is complete, from top to bottom, with both terminations ticking out! This is a MAJOR copper of a style seldom seen beyond miniature sized specimens, and I cannot emphasize enough the display impact of the 6 inch twin in the middle, in person. 15.4 x 6.3 x 4.1 cm
9.1 x 8.5 x 4.5 cm. A large, branching specimen of penny-bright copper from Arizona. This is not a wimpy "leaf" but is actually sturdy and substantial!
6.0 x 3.3 x 1.4 cm. Sharp, spinel-twinned copper crystals to 2.1 cm with a nice patina form an aesthetic, arborescent crystal cluster on this showy piece from the Grand Marais fissure in Lake Superior. Ex Seaman Museum Collection. This form of copper is not so common in Michigan, and its a pretty, intricate piece!
2.0 x 1.7 x 1.6 cm. Here is a wonderful thumbnail size specimen of the famous pseudomorphs of Copper after Aragonite from Corocoro. These floater specimens are well known from Bolivia for their great form and color, and this piece has the classic and unique form that has made these pieces some of the most well known and highly sought after pseudomorphs around. This specimen is a very fine example of this material. There hasnâ€™t been any significant amount of these specimens on the market in approximately 25 years, and they are often only found in old collections.
