A choice single crystal of the blood red "Eisenkiesel" habit, complete all around. With strong bright Hematite inclusions, these Spanish Quartzes are distinctive. The local name for these is "Jacinto de Compostela" and they are unlike any other Quartz.
A very rich specimen of several uncommon Copper species, most importantly Lavendulan. Also containing a sizable zone of Conichalcite, minor Azurite and what appears to be Barahenaite (not analyzed). The Lavendulan is present in thick bands, crusts and small crystals of several habits. The Conichalcite is in translucent green globules covering one entire face. Lavendulan is a Phosphate and also an Arsenate, with the complex formula ofNaCaCu5(AsO4)4Cl·5H2O. Not often seen on the mineral market except in small blebs or micromounts.
A fine transparent cluster of Dolomite crystals from the classic Spanish locality of Eugui, Navarre. An uncommon matrix piece, the crystals are up to 4 CM in diameter and very sharp, undamaged. Dolomite is a very common mineral and crystals are not rare at all, but sharp, gem clear Rhombs like this are really only found at this one locality and they are very rare in such quality. Some minor dark zoning is seen but overall these are white to colorless and mostly transparent. The penetration twinning is textbook sharp and clear, an excellent piece found in 1998.
Transparent cube, slightly elongated with beveled edges and light purple color. From the small digs at the Llamas site, this has both clear and lightly frosted faces, no damage but some contacts that can be seen through the cube from different angles. We are very impressed with the quality of these Fluorites, they are one of the best recent finds for the specie.
Resuperferolitica Mine, Santa Eufemia
8 x 6 cm (cabinet)
Ex. John Marshall collection, a very well crystallized Santa Eufemia Pyro with large individual crystals that exceed 1.6 CM. This is overall in excellent condition and is crystallized on 2 sides with large vugs filled with sprays and freestanding individual crystals. A super display piece from a very important locality.
Fluorite- gem clear tabular habit
stock #18.1- 140
Cantera Llamas, Duyos, Caravia
3.7 x 2.7 x 1.6 CM (small miniature/ large thumbnail (toenail))
A super toenail sized Fluorite with a very fine flattened cube form and top clarity. From the small but important Llamas Quarry in Northern Spain, this is in pristine condition. The matrix is a mass of small crystals of Fluorite all showing the elongations and beveled edges that are classic for this area. Choice.
Fluorite- Elongated gemmy cubes
Cantera Llamas, Duyos, Caravia
3.7 x 2.4 x 2 CM (small miniature/ large thumbnail (toenail))
Pre Holiday 2017
A super clear, nearly colorless (with a very slight tinge of purple) cluster of two elongated cubes. The crystals are in epitaxial orientation as well. The Fluorites from Llamas are almost always beveled on the edges and often elongated, sometimes on two different axis as is this one. No matrix at all, the back and underside were contacted and recrystallized, and one old cleavage break has also had some regrowth. The facing side for display is almost air clear, sharp and lustrous. A very good example of this small but impressive locality.
Sharp Fluorite with classic form of complexly stepped cubes (distinctive of some Asturias specimens) is the base for a spray of flat Barite crystals. Choice display specimen that is better in person, the Fluorite has a pale violet-blue color and a few purple phantoms. In fine condition damagewise, the delicate Barite blades are surprisingly all intact. Looks good from all sides this has no point of attachment it is fully crystallized on all faces. A remarkable specimen from all angles.
