4.7 x 3.7 x 3.0 cm. Old Yuma Mine vanadinites compare favorably with the best United States vanadinites, including the Apache and North Geronimo (Pure Potential) Mines. And Old Yuma vanadinites are less common. Lustrous, brick-red, hexagonal vanadinite barrels to 4 mm are richly and attractively scattered on the sculptural, mounded matrix of lustrous calcite rhombs on this classic combination specimen. The knob is complete-all-around and pristine. Ex. Jaime Bird Collection and probably dates to the 1960s or 1970s.
7.9 x 5.0 x 4.5 cm. Sharp, lustrous, reddish-brown, hexagonal vanadinite prisms to 1.5 cm very richly cover all sides of the sculptural matrix on this fine specimen from a brand new find near Mibladen, Morocco. The crystals on the side and back have an interesting brown coating. Expertly collected, all of the myriad of crystals are pristine. Highly representative of the species and new find.
7.4 x 4.8 x 3.5 cm. Sharp, lustrous, reddish-brown, hexagonal vanadinite prisms to 1.5 cm very richly cover all sides of the sculptural matrix on this fine specimen from a new find near Mibladen, Morocco. Some of the crystals on the front have a preferential coating of brown material, while those on the back all have the brown coating. Highly representative of the species and new find.
4.0 x 3.6 x 2.6 cm. Old Yuma Mine vanadinites compare favorably with the best United States vanadinites, including the Apache and North Geronimo (Pure Potential) Mines. And Old Yuma vanadinites are less common. Lustrous, brick-red, hexagonal vanadinite barrels to 5 mm cover the matrix on this classic specimen. The vanadinites have a preferential coating on one face. This piece probably dates to the 1960s or 1970s. Ex. Jaime Bird Collection.
7.8 x 6.5 x 5.0 cm. Gemmy, orange-brown vanadinite crystals to 5 mm are festooned on two faces of the masssive cerussite matrix on this fine specimen. Excellent, old-time material. Ex. Dennis Mullane Collection and probably dates to the mid-1960s. Note unusual crystal habit of the vanadinites.
7.8 x 6.7 x 3.8 cm. Gorgeous, mirror-bright, partially gemmy, brick-red vanadinite crystals compose this fine specimen of solid vanadinite from a new, 2009, Moroccan find. The sharp, hexagonal crystals range from tabular to very blocky and a large, blocky edge crystal reaches 2.3 cm. This is a near floater specimen. The crystals on the back are coated.
8.4 x 6.8 x 3.8 cm. Sparkly, partially gemmy, brick-red to rust-red vanadinite prisms to 8 mm richly encrust a very sculptural matrix of diverging, parallel-growth clusters of iron oxide-coated baryte blades from Mibladen, Morocco. This fine specimen is from the very small, late 1970s Moroccan find and was, until the great finds of the late 1990s and early 2000s, considered to be the finest vanadinite on baryte specimens from Morocco. They were very highly desirable. Highly representative of the species and find. This piece is exceptional, in that, it is an essentially pristine, complete-all-around floater. The myriad of crystals on the back are coated. Ex. Saller Collection.
8.0 x 4.8 x 3.3 cm. Sharp, lustrous, brick-red, hexagonal vanadinite prisms to 1.7 cm very richly cover all sides of the sculptural matrix on this fine specimen from a brand new find near Mibladen, Morocco. Some of the vanadinites on the top of the front have a preferential coating of brown material, while the vanadinites on the back all have the brown coating. Highly representative of the species and new find. Expertly collected, all of the crystals are pristine, front and back. This piece is a near floater, with only a thin attachment ridge on the bottom.
5.0 x 4.8 x 2.9 cm. Scintillating, gemmy, cherry-red vanadinite prisms to 1.0 cm are richly and aesthetically scattered on the bladed baryte matrix on this fine specimen from the finds 8-10 years ago.
11.4 x 7.2 x 4.8 cm. An unusual and fine cabinet pseudomorph of intensely sparkly, rust-red descloiszite pseudomorphing elongated vanadinite prisms from the less well-known Aurora Mine, Chihuahua, Mexico. The vuggy, sculptural gossan matrix is filled with prisms in a jackstraw pattern up to 1.8 cm long (some curved).
4.6 x 2.8 x 2.3 cm. Lustrous and gemmy hexagonal Vanadinite crystals up to 1.5 cm in size. The deep orange-red color, superb luster and gemminess, and the lovely geometry of the cluster makes the aesthetics of this miniature stand out dramatically from the crowd. Even better in person. Ex. Wendell E. Wilson Collection.
9.3 x 7.34 x 3.6 cm. For some time, "Endlichite" was considered a species, but is now classified as an Arsenic-bearing variety of Vanadinite. This lovely specimen hosts hundreds of classic, silvery, almost metallic looking, thin prismatic crystals of "Endlichite" on rhombohedral Calcite matrix. The "Endlichite" crystals have a light curve to them, which is very distinctive for this mine. A very graceful specimen, and virtually damage free on the display side. Ex. Brian Kosnar Collection.
7.8 x 7.5 x 4.8 cm. The sculptural, boot-shaped matrix is richly and attractively covered with sharp, lustrous, reddish-brown, hexagonal vanadinite prisms to 1.0 cm on this fine specimen from a new find near Mibladen, Morocco. The crystals are the richly concentrated at the crest and are partially gemmy. The vanadinites on the side and back have a preferential coating of brown material. Highly representative of the species and new find.
4.4 x 3.4 x 1.9 cm. A superb and aesthetic vanadinite specimen from the classic, but now hard to obtain source of the San Carlos Mine of Chihuahua, Mexico. Sharp, isolated, elongated, orange vanadinite prisms to 1.2 cm strikingly cover the gossan crust and are seriously complimented by the starkly contrast calcite. I particularly like the way the largest crystals are at the top of the piece. These came out in the 1970s and 1970s, with none since. Ex. Jaime Bird Collection.
9 x 8.6 x 5 cm. The San Carlos (Apex) Mine is a small, relatively unknown locality to many collectors. Yet, for brief periods in the early 1900s and again in the 1930s-1952, it produced some of the finest vanadinite in the Southwest (more information can be found in the MEXICO V issue of the Mineralogical Record). Most are small pieces, and many are lost to the damages of time. A cabinet specimen like this should be considered extremely rare. This is a very aesthetic cluster of branching crystals, arranged like a flower with larger crystals to 2 cm forming a core cluster, right in the middle. It has habit, color, and a flowing style that clearly stands out from pieces found at other vanadinite locales. This specimen from the Dr Miguel Romero collection was exchanged out of the Romero collection to a fellow collector, before the remainder of the Romero collection went on loan exhibition to the University of Arizona Museum. Romero traded it to Evan Jones, a fellow collector of Mexican classics, in the early 1990s. I obtained it from Evan by exchange in 2007, apart from my impending purchase of the Romero collection.
