Mexico
4.9 x 3.4 x 2.9 CM (miniature)
price: $120
Pre Tucson
Classic Adamite crystals from Mina Ojuela but with the more rare color. Well-defined mint green crystals on contrasting gossan matrix in good condition as seen. The crystals have glassy faces and translucent milky interiors. A nice affordable and attractive Adamite from this most incredibale locality. This can be trimmed to a pair of thumbnails but we like it as is.
Legrandite
stock #14.1-085
Mina Ojuela, Mapimi
Durango,
Mexico
4.7 x 3.5 x 3.2 CM (miniature)
price: $750
Pre Tucson
Bright yellow sprays of fine Legrandite crystals in a shallow vug. These crystals are gemmy and have a bright glassy luster, reaching to 2.4 CM in length. World-wide Legrandite is very rare and good pieces are prized. From the Robert Ray collection with label dating the piece to 1974, so this piece is part of the early top find at Ojuela. In fine condition and very esthetic, the world’s best Legrandite has come from this locality and from this era. Such nice quality is only available from older collections being dispursed, very little of quality has been found in the past few decades and nothing at all for a few years.
Adamite - classic pinwheel clusters
stock #9.1-018
Mina Ojuela, Mapimi
Durango,
Mexico
4.5 x 3.8 x 2.7 CM (miniature)
price: $650
Pre Tucson
Very fine light yellow-green crystals of Adamite arranged in the "pinwheel" type of radiating spray. A choice miniature in excellent undamaged condition from the classic finds about 20 years ago at Mina Ojuela. Good Mexican Adamites were once rather plentiful but this quality and form were never common. These are now quite hard to find and this is an especially elegant and esthetic piece. The radiating sprays exceed 2 CM across, these contrast with the gossan matrix. Displays well from most any angle, and the matrix is not the ultra fragile, crumbly type.
Quartz on Calcite on Aurichalcite
stock #17.1-557
Mina Ojuela, Mapimi
Durango,
Mexico
7.3 x 5.7 x 4.2 CM (cabinet)
price: $380
Spring 23
An unusual specimen ex Les Hitchings collection, obtained in 1963 as noted in his ledger; one of his earliest pieces. This is quite different from more recent pieces and has a fine composition overall. The Calcite and Quartz have a light mint-green color caused by the underlying copper minerals. A small area of Aurichalcite is noted on the matrix. The taller fingers or towers grade to a white to pale yellow color at the tips. Overall in excellent condition, the sparkle and luster are excellent. This dates back to the early years of Mexican mineral specimens being exported to the USA.
Mimetite
stock #13.1-145
Mina Ojuela, Mapimi
Durango,
Mexico
5.3 x 3.7 x 2.1 CM (cabinet)
price: $480
Spring 23
A fine "wet-look" Mimetite in elongated balls and fingers covers a contrasting matrix. Excellent color and luster in fine condition. The surfaces have a distinct sparkle as well. From the find about 7 years ago at Mina Ojuela, these look very much like the prized San Pedro Corralitos Mimetite from the 1980 era. As these are a more recent discovery the price for a fine piece like this are considerable less than the older material yet the look is very similar.
Mottramite covering Wulfenite
stock #22.1-033
Mina Ojuela, Mapimi
Durango,
Mexico
4.4 x 3.4 x1.7 CM (miniature)
price: $350
Fall 22
A miniature with great form and an unusual combination of specie. The specimen is fully covered by Mottramite in a botryoidal form that has enclosed underlying Wulfenite crystals. The form of the Wulfenite blades is still evident but they are not visible on the specimen surface. A very unusual replacement, and another example of the amazing processes that have taken place at Mina Ojuela. No damage and a fine example of Mexican Mottramite.
Hemimorphite - older find
stock #22.1-647
Mina Ojuela, Mapimi
Durango,
Mexico
5.3 x 4.4 x 2.7 CM (small cabinet/ large miniature)
price: $480
Fall 22
Exceptional and esthetic NATURAL Hemimorphite from finds about 15 years ago at Mina Ojuela. In fine, undamaged condition there are two generations seen here with the larger free standing crystals being the only ones with color. The light green-blue hue came from a small find of fully natural color caused by Copper Carbonates in the area. Many people know that a few years ago some artificially dyed (faked) Hemimorphite with a vivid blue color came into the market. It was at first accepted as natural since the mine had at one time produced these lighter color natural Hemimorphite. This is a choice example of the now rare natural color Hemi from Mina Ojuela, looks fine from any angle too.
A super aesthetic Fluorite from the great Mina Ojuela. A single sharp purple cube is delicately perched on a sliver of matrix. The matrix though small has a lot of other mineral species on it as well. A scan by loupe finds Conichalcite, Pyrite, Quartz, Galena and Calcite, all crystalized. The Fluorite though is the star, it has the rare bright red fluorescence that some specimens from this mine exhibit. The isolation and good rich color of the crystal give this an strong visual appeal. Overall this is in great condition, the front or display side is in fine shape, the back and side have cleave/contact that is not seen from the fron. It is amazing that this mine has operated for centuries and has been a source of remarkable and often surprising minerals to this day.
