Velvet blue-green spheroids on a gossan matrix, the main ball here is 1.7 CM in diameter. From finds at Mina Ojuela, this is super well-defined and a great representation of the specie. There were some outstanding finds in 2009-10 which brought a lot of Rosasite to the market, most was in crusts and clumps of botryoidal masses but isolated balls were very rare and over 1 CM were super rare. This is an esthetic, large and well-formed ball from those finds. A great addition to any Copper or Carbonate suite.
Legrandite
stock #AX-4-287
Mina Ojuela, Mapimi
Durango,
Mexico
3.6 x 2.3 x 2.1 CM (small miniature/ large thumbnail (toenail))
price: $860
Sharp, gemmy and in fine condition, a vug in gossan matrix protects sprays of bright yellow Legrandites. This is a famously delicate and rare mineral, the best crystals in the world are from Mexico, many years ago at the original Flor de Peña Mine and from Ojuela very sporadically. Several years have passed without any new finds of quality. This piece dates to the mid 1970 era. Small but choice and remarkably perfect this can be trimmed to a killer thumbnail if wanted.
Adamite crystals clustered on botryoidal gossan matrix showing purple terminations and almost white center areas. A very attractive older specimen from the great Mina Ojuela, the world’s best source for purple Adamite. The largest crystals are 2 CM tall and are free standing. In very fine condition with no damage visible. Purple Adamites are quite prized by collectors as these the rarest color. This sort of bicolor in such large and distinct crystals is even more uncommon.
SOLD Aurichalcite
stock #SOLD 20.1-457
Mina Ojuela, Mapimi
Durango,
Mexico
7.3 x 4.4 x 3.4 CM (cabinet)
price: $0
The amazing mines of Mina Ojuela have produced many wonderful and colorful minerals over almost 4 centuries. Aurichalcite is classic for the locale, this one with very good color and a few clear Calcites for contrast. The acicular needles that are protected in the 2.5 CM vug are in fine condition, the other crystalized areas show some matting of the crystals. Displays well.

3.3 x 2.6 x 1.7 CM (thumbnail)
price: $140
Bundles of bi-color Adamite crystals on Gossan matrix. a choice thumbnail in fine condition. The Adamites from Mina Ojuela are one of the mineral world’s best values for quality and still reasonable cost. A nice example with a pale pink to red color contrasting with a yellow green hue.
Mottramite covering Wulfenite
stock #22.1-045
Mina Ojuela, Mapimi
Durango,
Mexico
9.6 x 6.8 x 4.7 CM (cabinet)
price: $590
Strangely esthetic and in fantastic condition, this is a rather rare example of this find at Mina Ojuela. Crystals of Wulfenite have been covered and mostly replaced by thick masses of Mottramite. This material was found in a small but exciting discovery in 2018-19. It was distinctive and most pieces were quickly snatched up by collectors. This is being recycled from that find and is well above average for quality and form. A very nice addition for a suite of pseudomorphs, Mexican classics or just strange and wonderful minerals.
Several habits of well-formed Cerusite crystals are scattered on a Pyrite matrix. The Cerussite covers both sides of this piece but the best are on the side shown here. In fine condition with excellent color on the crystals. It has been said the green coating is Posnjakite and other sources say it is Langite. Both are logical possibilities but this is untested. No matter the source, the color and sharp crystal habit make for a very attractive specimen. From a find in 2015 at the Ojuela Mine, one of history’s greatest sources of mineral surprises.
Aurichalcite
stock #AX-10-868
Mina Ojuela, Mapimi
Durango,
Mexico
7.3 x 6.8 x 3.8 CM (cabinet)
price: $420
A rich and large vug of Aurichalcite crystals in hairlike masses and clusters. Excellent color and in very fine condition. A classic from Mina Ojuela, this is a fairly old (1970-80 era) specimen and far better than the usual seen from this locality .It has a very large blue zone, long hairs (to well over 1 CM) in thick layers and has real display impact. Very few minerals in the world have this exact color, it stands out in any cabinet!
