Stacked and clustered Calcite crystals with triangular cross sections and triangular faces. In excellent condition as seen only some bruising to note on outside edge and backside contact. The color is a salmon pink to orange hue. From a small quarry in Guiyang the specimen has a second generation of tiny Calcite crystals on the lower faces of the main crystals.
Hanson Aggregates Midwest Inc., Silica, Sylvania Twnship, Lucas County
4.5 x 3.6 x 2.8 CM (miniature)
Blue Celestite (Celestine) on matrix in an aesthetic arrangement. The condition is excellent, this from the famed Finley Arch region where this association on Dolomite is especially classic. In excellent condition and with gemmy transparency, this is a choice miniature of the specie from a little known quarry.
Classic Illinois Fluorite with no matrix, mostly a cluster of sharp yellow cubes on massive Fluorite. The crystals are very slightly zoned with thin outer edge lines that are quite subtle. In very good condition overall, sharp edges, corners and good transparency. The color is mostly yellow but with a hint of orange in person. The larger crystals are over 2 CM on edge, and the luster is quite glassy. Specimens of this quality have become quite hard to get at reasonable prices if at all.
Pyromorphite - classic British
Roughtongill Mine, Caldbeck Fells
4.8 x 3.8 x 3.7 CM (miniature)
From the Roughtongill Mine this is nearly all Pyromorphite with almost no matrix. A solid crystal mass with two generations the larger crystals are more green, the smaller more yellow. Ex Les Hitchings collection, obtained in 1974 during a collecting trip to the mine with Richard Barstow. A choice piece with crystals to 1.3 CM and in very good condition. The tiny bit of matrix is crystallized Quartz so the specimen is quite heavy and sturdy.
white Prehnite casts
Malad Quarry, Malad, Mumbai District
9.6 x 4.2 x 2.5 CM (cabinet)
Really unusual hollow casts of sparkling white crystalline Prehnite sprinkled with small clear Apophyllite crystals. From Malad (Deccan Plateau of India) It looks like this has grown over Anhydrite crystals (and not Laumontite) that are now gone. The backside of the specimen is hollow, the void of the original crystals is clearly seen. No damage or bruises, this is a perfect and complete replacement unlike anything we know from India. Such replacements are well-known in the Northeastern USA trap-rock zones, but never in such elongated, slender fingers and always with typical green color. White Prehnite is surprisingly uncommon, this piece also has very distinct small crystal bundles of flattened stacks of lath-like Prehnite crystals best appreciated with magnification. Although the Deccan Plateau produces many mineral specimens, this habit and style is really unusual and comes from a find more than 16 years ago.
Quartz included by Dumortierite
Vaca Morta Quarry, Serra Da Vereda, Boquira
2.7 x 2.2 x 1.6 CM (thumbnail)
Bright blue inclusions of Dumortierite are visible inside and through Quartz crystals. From a find at Vaca Morta (Bahia, Brazil) a very nice example in thumbnail size. The blue color is mostly concentrated on the backside of this specimen along a crystalized contact plane and there is more near the terminations. This color is quite similar to the uncommon Shattuckite inclusions and a bit brighter than Papagoite. A vivid and still affordable Quartz.
Fluorite - pink Alpine
Lassner-Meissner, Chamonix, Bonneville
2.6 x 2.6 x 1.4 CM (thumbnail)
A sharp classic habit French Alpine Fluorite with excellent color and no damage. This crystal grew against a matrix (typical in this type) but it was long ago naturally detached and has since recrystallized on the contact areas. As a result this is a floater, it is crystalized or rehealed on all sides, something very rare from Alpine cleft Fluorites. From a less well-known find years ago in the Mt Blanc Region, this is translucent to transparent, has very good luster and with perfect edges and corners.
Fluorite - classic pink Alpine
Les Courtes,Chamonix, Bonneville
3.5 x 3.3 x 3.2 CM (small miniature/ large thumbnail (toenail))
A choice and sizable single crystal of well-formed Fluorite having deep pink-red color and lightly stepped faces which gives a frosted texture on some parts. Over all in fine condition, only the underside has some contact/cleaving not seen from the front display. This from the Les Courtes Mountain which lies between the Argentière and the Talèfre Glaciers in the heart of the classic Mont Blanc Fluorite zone. This locality is not so well-known and rarely visited; it is a very demanding technical assent. A few finds of Alpine Quartz put the location on the mineral map but almost no records of Fluorite. Not only an attractive crystal, this is a very rare locality almost never available.
