A small cabinet Legrandite with great color contrast and many gemmy crystals. The red gossan matrix has a main open vug that is filled with bright yellow to orange crystals of Legrandite sitting on a light green druse of copper rich Austinite. Close exam with good magnification finds some tiny Kottigite, Adamite and other micro crystals as well. The main interest however is the Legrandite. The largest crystal sprays (which reach 2 CM) are pocket bound and so are not as well-defined, however the smaller crystals are impressively complete and perfect, many are free standing, sharply terminated, lustrous and transparent. Good Legrandites from Mina Ojuela are highly regarded, they are by far the best in the world and have only been found a few times in small numbers. This one is from the Benny Fenn find so is an early example and a good value.
Milpillas Mine, Cuitaca, Municipio de Santa Cruz
7.1 x 5.1 x 3..4 CM (cabinet)
Sharp, highly lustrous Azurite crystals in a cluster on a contrasting reddish matrix. An early find Azurite specimen at Milpillas that is rather different in habit from later material. In excellent condition, clean and with bright "electric" blue crystals that are up to 1.6 CM and translucent to transparent. This mine is certainly a modern classic locality, and is now closed. During the short working life of the mine it became the world's greatest source of fine Azurites. The many diverse styles, habits and forms continue to make Millpillas a highly collectible locality. This is both a pretty, choice piece and a rather different esthetic. Excellent value.
From a relatively new find (2020-21) by Denis Beals; these are larger rose Garnets from an area of the Sierra de las Cruces. This site has produced a few relatively large Garnets embedded in a hard Rhyolite matrix. Noticeably different in habit and look from the previous finds in this region, this piece is an excellent example. A cluster of two main intergrown Grossular crystals show good luster and contrast well with the matrix. Some contacting is noted, there are geometric imprints of other Garnets and some rougher faces, as was true of every piece we examined from the find. Nevertheless, while this is not a piece for perfectionists it is still a fine and colorful Mexican Garnet unlike anything else from the region.
A killer Hemimorphite from the late 1960's vintage find with unusually large phantom crystals. In excellent, undamaged condition, even the tiny crystals seem to be perfect, glassy and sharply terminated. The largest crystal spray is over 4.9 CM tall and is well-isolated. The main crystals have a slightly yellow color at the top, the body is white and the base has a dark brown to black phantom. Looks fine from any orientation, this is totally unlike the vast majority of Mexican Hemimorphite. In person the luster is brighter than the photos show, a real killer, the more recent finds from Santa Eulalia and and Mina Ojuela are very different, this sort is almost never available. Outstanding for the major crystals of Hemimophite.
An emerald green mass of Brochantite crystals standing like grass on a miniature sized lawn. These are translucent to transparent crystals with thicker and less fragile form. Most of the Brochantite from here was the very slender and fragile needle habit and often was laying flat on the matrix. The standing "jackstraw" specimens are especially desirable. Already a classic from Milpillas which is one of the world's greatest Copper mines and source of amazing Azurite, the Brochantites from this locale are also world class. A very nice miniature with great luster and color best appreciated in person. In excellent condition, the mine is now closed forever so there will be no more of these.
Pyrite on/replacing Pyrrhotite
Contessa Mine, Santa Eulalia District
7.2 x 6.5 x 4.4 CM (cabinet)
Fantastically esthetic and perfectly formed curving Pyrrhotite crystals are covered with bright golden Pyrite. In perfect undamaged condition, ex Arizona Desert Museum. The main Pyrrhotites are slender sparkling gold crystals. With tapering habit some also have twists or curves. The Pyrite on the crystals faithfully follows the crystal striations. A rare and impressive Mexican specimen, the matrix is a mix of sulphides (Sphalerite, Galena) with Calcite, Quartz and Dolomite. The largest, slender crystal is over 6CM long and crowned with a rosette of small Calcite crystals. Way more impressive in person, this is not a typical Mexican Pyrrhotite!
A small, well-composed specimen of Amethyst perched on a contrasting matrix with a druse of greenish Epidote. From the prolific finds at Piedra Parada, the Amethyst is distinctly sceptered and in perfect condition. These Amethyst when they are perfect like this are one of the best current values in minerals. We hope the locality can continue to produce for a long while.
Wulfenite with Calcite etc.
Mina Ojuela, Mapimi
3.6 x 3.3 x 2.6 CM (small miniature/ large thumbnail (toenail))
Late Summer 2021
Older blocky style Wulfenite crystals with small Calcites on gossan matrix. The majority of the large crystals are complete and slightly distorted with a burnt orange color and good luster. In good condition overall, some minor damage exists but is not very evident. Another modern classic from Ojuela.
