4.7 x 2.8 x 2.8 cm. A fine thick "book" of platy, hexagonal crystals of hematite, with a gleaming metallic luster. This elegant form of hematite is classic from Brazil, and also from Switzerland - but they are uncommon compared to most hematites. Old material from the 1970s.
9.6 x 7.8 x 5.4 cm. A fine example of this now well-known combination from Lechang. Three pristine, slender, gently tapered crystals of quartz, with a hint of color from hematite inclusions, lean at different angles from their natural base of massed crystals of platy hematite intergrown with more quartz crystals.
6.7 x 4.7 x 0.3 cm. A classic combination specimen from Cavradi Gorge, Switzerland. Splendent, beautifully striated, intergrown hematite plates are very nicely highlighted by a scattering of gemmy and lustrous, wine-red rutile crystals. There are rutile crystals on both sides and the largest rutile is 7 mm, of which there are several. Ex. George Elling Collection.
4.8 x 4.2 x 1.8 cm. A fine, splendent, very sharp, complete all-around hematite crystal with a fabulous herringbone pattern from Boa Vista, Ouro Preto, Brazil. The crystal is attached to massive hematite matrix. Ex. George Elling Collection.
4.0 x 3.5 x 3.2 cm. A fine, lustrous, burnished brown to black, hematite after marcasite floater specimen from the White Desert of Egypt. A fascinating crystal form. These came out a number of years ago, with none since.
13.4 x 9.0 x 6.2 cm. The classic "kidney ore" hematite from England (so called because of its frequent similarity to a kidney in form) often forms really unusual and pretty specimens, but only rarely does it have this shocking luster to it - like metal. Probably it is very slightly buffed as so many were by the miners back in the late 1800s and early 1900s when most were collected.
5.3 x 4.0 x 3.6 cm. Two striking, splendent, fan-shaped hematite crystals to 2.0 cm are atop massive hematite matrix on this superb specimen from a very uncommon Romanian locality - Dognaczka. The hematite crystals have exceptional form and hematite itself, is rare from this locale. Ex. George Elling Collection.
3.4 x 3.3 x 1.8 cm. An exceptional cluster of sharp, lustrous tabular Hematites from the Wessels Mine. This specimen has very good aesthetic balance, with the smaller crystals framing the large 2.2 cm main crystal wonderfully. Ex. Charlie Key.
6.5 x 3.8 x 3.3 cm. The Veta Grande Claim, Dome Rock Mountains of La Paz County, Arizona has produced what are generally considered to be among the finest United States hematite specimens. This fine plate consists of mirror-bright hematite plates nicely scattered amongst a "forest" of water-clear quartz crystals. The 3.1 cm quartz “sentinel" is striking. The largest hematite crystal is 1.6 cm. Specimens of this quality were found in the 1970s. Ex. Richard Hauck Collection.
4.2 x 3.0 x 2.8 cm. A sculptural and excellent cluster of splendent, dark gray, sharp, blocky/pyramidal hematite crystals from the famous Wessels Mine of South Africa. These unusually formed crystals are doubly terminated. The backside has an overgrowth of very sparkly specular hematite. Ex. Rob Smith Collection.
4 x 4 x 3.8 cm (largest). Four complete octahedrons of magnetite have been replaced (pseudomorphed) by hematite, retaining the octahedral form of the original magnetite. You can see interesting concentric triangular-shaped terracing on the faces.
A dramatic and aesthetic miniature of very highly lustrous to sparkly to matte-finish octohedral hematite pseudomorphs after magnetite from the 2002 Argentina find that was such a hit at Tucson. The tall crystals are very pagoda-like and are partially hoppered on all four sides. The cluster of perfect octohedrons at the base perfectly compliment this fine piece. 4.6 x 3.5 x 2.4 cm
A showy CABINET-sized, old-time classic from the iron mines of Cumbria, England. Lustrous, hematite-tinted quartz crystals to 7 mm rest on a coating of specular hematite, which coats botryoidal hematite kidney ore. Nice! 11.0 x 6.1 x 4.3 cm
6.8 x 6.4 x 5.4 cm. This bizarre and beautiful form of botryoidal hematite is often called "kidney ore." It is classic from England, but actually a lot rarer in good American specimens. This specimen is solid hematite, and it presents a wonderfully bubbly, shiny display face. Ex. Russ McFall Collection.
3.8 x 2.9 x 2.8 cm. Swiss smoky quartzes have a deserved reputation as the best in the world. This miniature features crystals with an intense gemmy clarity that simply cannot be surpassed. This specimen has the attractive addition of platy crystals of hematite. Ex. Richard Hauck Collection.
