Small but bright, sharp and gemmy free standing crystals of bright yellow Legrandite. These crystals line a vug with a druse of smaller more pale Legrandites as a background. A small area of Smithsonite in Scalenohedral crystals is also noted on the back of the matrix. This is an older specimen from 1970 vintage finds. Magnification reveals a few broken crystals at the edge but those in the central area are complete and perfect. A very good budget specimen.
Austinite
stock #19.1-753
Mina Ojuela, Mapimi
Durango,
Mexico
4.8 x 4.3 x 2.4 CM (miniature)
price: $800
Austinite is usually only seen as micro crystals but the finds at Mina Ojuela were by far the best and largest ever found. This is a superb example of the radial crystals of large size and in perfect condition. Esthetic, bright well perched balls of sparkling crystals stand out on the matrix. This Austinite was part of a single small pocket found in 2018, none had been seen for many years. This is far better than typical material and a very choice example.
Killer thumbnail of sharp Manganoan Adamite crystals clustered like a crown on a base of lemon yellow to green Adamites. The Manganoan crystals have light purple and reddish-pink zones with glassy luster, transparent in areas. . Ex collections of Willard Perkins (inventor of the Perky box) and Kay Robertson. In excellent condition, the display side is perfect and competition grade, the backside is contacted where it grew on host rock. With all the fine Adamites to come out of Ojuela it can be hard to find one that is exceptional or stands out. This one is top level with a unique form.
A Mimetite from older (1962-64) finds at Mina Ojuela that looks very different from most later materials. The Mimetites are unusually sharp and lustrous, many prisms with hoppered terminations. The crystals are brilliant yellow on one side of the specimen and a dull brown on the other side. Mixed in are several small Calcite rhombs which are transparent too. Most of the crystals are perfect and undamaged but there also spots with damage that keeps this far less pricey. Although not very easily seen without magnification they are there. These older Mexican Mimetites are unlike the later and larger finds that are very well known (San Pedro Coralitos etc), these are not the usual rounded form but are more glassy and quite prismatic.
Adamite
stock #6.2-1052
Mina Ojuela, Mapimi
Durango,
Mexico
5 x 4.1 x 1.1 CM (miniature)
price: $380
Inter-connected half-balls of bright green Adamite forming a plate with minimal matrix. The balls have bright luster and are composed of distinct small curved crystals. Early 1960 vintage specimen from Mina Ojuela, the backside of this is flattened being contacted with a minor amount of adhering matrix. The front is in fine, undamaged condition. Distinctly different from more recent finds and brightly fluorescent.
Cerussite - blue-green inclusions

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.
The rare coper mineral Kobyashevite was discovered and described in 2011. A close relative of Devilline this Copper Sulfate specie was an exciting find at Mina Ojuela this year, and in this deposit the specimens are impressively large and attractive, certainly the worlds best. It seems that these specimens are postmining redepositions and are always partly overgrown with small needles of clear Selenite. The best examples have a rich blue-green or Turquoise
color and when this is deposited on calcite crystals these have a very esthetic presentation. This specimen is in excellent condition and is the most attractive I have seen from the find. A choice and colorful rarity.
Adamite - Manganoan
stock #AX-11-043
Mina Ojuela, Mapimi
Durango,
Mexico
2.7 x 2 x 19 CM (thumbnail)
price: $475
Late Summer 2018
An especially esthetic, sharp flower-like burst of Manganoan (purple-magenta tipped) Adamite. This cluster rests on a solid gossan matrix like an ice cream cone, and has excellent proportions. Fine luster and condition, in person a little more purple color is noted. Ojuela produced only a few of these that looked this good, a quality, competitive thumbnail. Collected pre 2000, perhaps much older.
