Grossular (Raspberry Garnet)
stock #10.1-274
Lago de Jaco,Sierra de la Cruz, Municipio de Mojada
Coahuila, Mexico
6.6 x 4.7 CM (cabinet)
price: $340


From 2009 mining at this classic Mexican location, this is a far better than average example of this rare garnet variant. The main crystal here is 2.3 CM across, very lustrous, dark raspberry-red and in pristine condition. This is quite sizable for the locality and has been carefully exposed so it sits well on the matrix. Some minor crystals have typical damage that shows the dark core of the garnets. Since 1920 these garnets have sporadically been available but good ones have always been rare.
Grossular (Raspberry Garnet)
stock #10.1-276
Lago de Jaco,Sierra de la Cruz, Municipio de Mojada
Coahuila, Mexico
7x6.8 CM (cabinet)
price: $300


A very fine example of the recent finds at this classic location! An esthetic 'Mountain" of matrix hosts several deep red grossular crystals up to 2.2 CM. The "summit" is a well exposed sharp 1.7 CM crystal that presents well from all sides. The major crystals are in excellent condition, the backside has some missing/ broken crystals from the area where the matrix was removed, these are not seen from any display angle. Much better than average!
Pyrite, Magnetite and Xenotime (Y)
stock #1092-JM-1578
Hudson, Middlesex County
Massachusetts, United States
10.9 x 8 CM (cabinet)
price: $425


A Massachusetts rarity, from the John Marshall collection from a one time find over 40 years ago, during the construction of I 495. Two large, complex pyrites to 4.4 CM are perched on a jumble of micro crystals mostly Magnetites with numerous Xenotime. The right side crystal is in perfect condition, the left shows an old stress crack that is partly rehealed. An exceptional example of this find, I have not seen any better ever. Displays well.
Rhodochrosite with Acanthite, Native Silver, Sphalerite , Chalcopyrite etc.
stock #9.1-132
Wudong Mine, Wuzhou Prefecture
Guizhou, China
6.8 x 3.7 CM (cabinet)
price: $500


A great multi specie Rhodochrosite and Silver piece that has lots to look at! The Rhodo rhomb is 1.6 CM in size, sharp with rich red color. It is resting on a mass of crystalized Sulfide minerals, Sphalerite and Acanthite being the main ones and has native Silver in wires and curling clusters scattered. The rare associations are well presented, few Wudong area Rhodos have Silver associated, and few of those are esthetic.
Beryl V. Emerald -vanadium rich
stock #4.2-387.1
Malipo, Wenshan
Yunnan, China
7.9 X 4.6 CM (cabinet)
price: $220


A quite sizable (7.9 CM) and impressive Chinese Emerald with the typical color from this find. This Beryl is not gemmy except on thin edges and not colored by Chromium as are the Colombian Emeralds. Despite that this is still attractive and affordable. The crystal has been repaired (1x) and shows also a natural break and re-healing. A very good addition to a suite of Beryl, Chinese minerals or just as an attractive display piece.
Smithsonite (Deep green, ex John Marshall Collection)
stock #0287-JM-455
Kelly Mine, Magdelena district
New Mexico, United States
9 x 6.6 CM (cabinet)
price: $875


Super deep rich color, no damage and large size from mining in the late 1950's. These are already cherished classics for their color and luster. Much more green than the usual blue color, displays well and a very good value
Azurite with minor Malachite
stock #4.2-539-.2
Tongshan Copper-Iron Mine, Guichi City
Anhui, China
7.4 x 6.7 CM (cabinet)
price: $140


A big, bright blue sparkling specimen with Azurite crystals densely packed on the display faces. The copper deposits in this area of Anhui province have been mined for thousands of years, probably the longest continuous operation on earth. Small scale mining lets specimens escape the huge crushers that are used elsewhere. Very attractive and affordable.
Calcite with Pyrite (ex. John Marshall)
stock #0292-JM-3826
Shullsburg, Lafayette County
Wisconsin, United States
9.4 x 6.8 CM (cabinet)
price: $240


Classic calcite on sulfide and dolomite matrix from the great discoveries at Shullsburg. Esthetic and well presented, the calcites reach 3.2 CM. The backside isalso displayable. The front display face appears damage free (magnification finds micro nicks)there is contacting on the reverse but all in all it looks pristine. These are well respected as great and distinctive specimens, this is a good affordable example.
