Fluor-Buergerite
stock #19.1-255
Mexquitic
San Luis Potosi, Mexico
2.1 X 1.6 x .8 CM (thumbnail)
price: $160
Spring 2019

A pair of perfect small Fluor Buergerite crystals are laying on contrasting matrix. From the type locale, this rare member of the Tourmaline group is only available from older pieces like this, none has been found for decades. No damage, a well composed thumbnail.
Turquoise -old, very high quality
stock #19.1-245
Cananea
Sonora, Mexico
6 x 4.7 x 2.3 CM (cabinet)
price: $500
Spring 2019

A very rich, dense turquoise weighing 52 grams from a 1960 vintage find. Ex Hitchings collection this has a small surface polished with the rest left in original state. This is a top grade lapidary rough that is a fine example of this material. It is uncommon to see good non-doctored Turquoise as most on the market is either faked, dyed or altered in some way. This is an excellent, real and colorful Mexican piece with a vivid intensity that is very impressive. As an important Copper specie this is under-represented in most collections.
SOLD Fluorite on Celestite
stock #SOLD 18.1-541
Tule Mine, Melchor Muzaquiz
Coahuila, Mexico
7.6 x 5 x 2.3 CM (cabinet)
price: $0
Spring 2019

Ultra-esthetic, incredible geometric form and with great contrast, just a fine Fluorite. From the Tule mine, a few of these turn up every few years, this one from 2017. Very few have this simple perfection. there is no damage and the Fluorite is perfectly transparent, zoned and as seen has a fantastic stepped cube architecture. The matrix is a series of flat Celestite crystals with terminations showing along one edge. A modern Mexican classic and worthy of a place in any fine suite of Fluorite.
Selenite (very clear gypsum crystal)
stock #19.1-238
Naica Mine. Naica, Municipio de Saucillo
Chihuahua, Mexico
5.7 x 3.1 x 1.1 CM (cabinet)
price: $240
Spring 2019

Textbook perfect, sharp and transparent, a single doubly terminated Selenite from the famed Naica Mine. This is a 1970s vintage specimen in fine condition as seen. There are a few wispy inclusions that are not visible on some display angles, the exterior luster is very glassy with a few areas with very minor frosting. Overall this is a choice example. The Naica mine produced a lot of Selenite in its day. Not much that came out was this fine, most had some damage or edge issues. Now that the mine is closed these better specimens are becoming treasures.
Calcite- Violet color gem clear
stock #16.1-316
Mina San Martin, San Martin, Municipio de Sombrerete
Zacatecas, Mexico
4.9 x 4.8 x 3.5 CM (miniature)
price: $290
Spring 2019

Glasslike faces with high luster and very sharp edges define this older Mexican Calcite. The crystal is twinned and transparent with fine violet color throughout. The reflective faces makes this hard to show to well in photographs but in person it is striking. The display side of the piece is in fine shape, the bottom and rear are contacted or broken in areas that can be concealed by display angle. otherwise only very tiny edge rubs are found with 10X loupe, this is naked-eye clean and impressive for any Calcite.
Cerussite - blue-green inclusions
stock #18AX-29-114
Mina Ojuela, Mapimi
Durango, Mexico
6.8 x 4.4 x 4.2 CM (cabinet)
price: $490
Spring 2019

An incredible Ojuela Cerussite that is a mix of colorless, green and nearly black Cerussite crystals with minimal matrix of Sulfides, mostly Pyrite. From a find about 5 years ago there were not many as fine as this. Slender, flattened and blocky prismatic habits with and without twinning in exceptional condition. The quality is amazing for this delicate mineral. The darkest Cerussites are included by a dark Sulfide, probably Galena. The green-blue color is an especially nice touch when seen on the clearest crystals. This could be trimmed to a killer miniature but the overall specimen seems to have greater mineralogical interest if kept intact.
Wulfenite on Mimetite -New find
stock #18.1-546
San Carlos Mine, Municipio de Maunuel Benavidas
Chihuahua, Mexico
3.2 x 2.6 x 1 CM (small miniature/ large thumbnail (toenail))
price: $1250
Dec 2018

A killer toenail of fine orange-red Wulfenite with perfect, textbook form. The contrasting matrix of Mimetite adds a great contrast. From the new find at San Carlos Mine, this is unusual as it is perfect, undamaged and well trimmed. This was a small but important find, the mine previously was known only for some fine Vanadinites decades ago, these new Wulfenites were a big surprise. This was the best in this size that we saw and it is much more impressive in person. Can be trimmed to a fine competition grade thumbnail, but certainly looks fine as is.
Wulfenite with Calcite & Mimetite. - New find
stock #18.1-552
San Carlos Mine, Municipio de Maunuel Benavidas
Chihuahua, Mexico
3.4 x 2.3 x 2 CM (small miniature/ large thumbnail (toenail))
price: $390
Dec 2018

From the exciting new finds at the San Carlos Mine, choice gem clear Wulfenites resting on glass clear Calcites and yellow Mimetites balls. The Mimetites are also included inside the Calcite, especially impressive under magnification. In perfect condition by naked eye, micro damage can be seen at 20X magnification, this is certainly not significant and is essentially perfect especially for this delicate mineral habit of the beveled edge blades. We have handled a lot of this find and this habit, color and association is unusual and very esthetic. Better in person too.
