Extremely high lustre, good size, and showy aesthetics make this one of the very best such specimens for the locality, which is near to where teh Calaveras axinites were found long ago. Garnet, however, is much more rare and this is thus a significant locality specimen.

Superb, lustrous jet-black crystals nicely isolated on matrix! Exceptional for the material!
SHARP specimen with really lustrous crystals of this rare species, especially a 2-cm-long doubly-terminated crystal right in the front-left. That one is partially covered with the andradite garnet that makes up the matrix as well
A stunning miniature, of this classic combination of species for Wessels. Few are found with such a wonderful and aesthetic combination of the garnet coating on hematite! this is essentially one large,elongated crystal of hematite, complete all around save for small contacts near the base.
Another stunning miniature, of this classic combination of species for Wessels. Few are found with such a wonderful and aesthetic combination of the garnet coating on hematite! The hematite here is 2.7 cm and is sharply twinned, as you can see from the reflections . More andradite could be picked off, as the owner wishes, to expose more hematite along the righthand edge, but I like the coating the way it is covering all the crystal but the shockingly fine twin planes facing out..
A dramatic and very large single hausmannite crystal showing intricate stepped growth on all faces, that measures 4 cm on edge, is the visual center here. It is an impressive specimen made pretty by the accenting garnet along the sides. In person, it can be displayed either vertically as shown, or horizontally, to equal effect . I should add that this style of hausmannite rarely has good lustre but we do no thave that problem here....it has lot sof sparkle for a black mineral!
An elegant specimen with a strangely flattened, tapering, 2.5-cm hematite crystal popping up in the middle of the matrix, coated on one side completely by andradite garnet.
Andradite garnet here completely coats on all sides, like a drape, the underlaying hematite crystal which has perfect crystallography and now looks like a sparkling red hematite more than anything! That crystal is 2.7 cm tall. Pristine and complete, this is a most unusual display specimen!
Sharp, lustrous,jet-black hausmannite crystals to 1.5 cm perched on a stunningly contrasting matrix of garnet! Beautiful, rich specimen that is both significant for the species and displays phenomenally.
We had only two such specimens in the whole collection of thousands of pieces, of these strange cast pseudomorphs of minutely crystallized, sparkling, andradite garnet that have replaced twinned rhodochrosite crystals. I had only ever seen 2 others , before. These look just like the famous pseudo-triangular crystals one saw from Mt St Hilaire in Quebec, in the 1980s. But, made of garnet! This one is shaped like a shield, very tapered, with the interior completely lined with crystals of gaudefroyite that stick out to one side.
A very rare garnet specimen from a small find in the 1980s that produced these waxy-lustered, red andradites in record size crystals for the mine. The large crystal here is 1.2 cm and the form is SHARP! For the location, these remain unequaled to my knowledge and are certainly rarely seen for sale. This is the first I have had in a long time.
Superb, exceptionally lustrous Gaudefroyite crystals to 1.5 cm festoon this matrix of bright sparkling garnet. This is a very rich specimen at, I think, a very cheap price as the pics do not do it justice for its significance and aesthetics!

This one is shaped like a 3-dimensional map where there are folds up and down to illustrate heights. It is very aesthetic, and more impressive in person! It is complete all around and made up of garnet on the front display, with the backside completely lined with crystals of gaudefroyite and a few minor ettringites. There is a coating on the backside, but the gaude's sticking out to the sides are, luckily, clean and lustrous, and serve to nicely accent the flanks of the rhodo crystals.
WOW! A SHARP, lustrous, very well-formed garnet crystal measuring just over 2.5 cm across, here lays well-exposed on a nicely trimmed matrix! I had never seen one of these before myself, and so I showed it to a few people who know better the more uncommon European material - and they were very impressed. It was mined from the Upper level of this (much older) mine in 1960-1962 and was apparently a one-time find of just a few specimens. I am told by Leithauser and others that this is one of the bery best, of the top few pieces. Formerly in the collection of noted German collector Paul Stahl and sold to Leithauser by German dealer Helmut Brueckner.
A stunning thumbnail, one that rgabbed me amidst hundreds of simply "small specimes" I have seen, as a piece with balance and significance that shows best in this size range, and not just "a small rock." This piece features a large, glassy and gemmy, grass-green demantoid crystal, measuring 1.7 cm in length, framed by smaller crystals. All of them are perched on a natural little pedestal of matrix and the cluster is complete all around. MUCH BETTER in person.
