Fluorite -classic zoned crystals
Minerva #1 Mine, Cave-in-Rock, Hardin County
6.4 x 5.6 x 4.8 CM (cabinet)
A super blue to yellow-orange zoned Fluorite with excellent form and outstanding surface modifications. A modern American classic, this is a choice display quality specimen that has a main cube presenting a textbook perfect inset in the largest face. Careful examination will find
a few very small edge rough points, which are almost inevitable. Overall however this is in very choice condition. The backside is the former point of attachment and is contacted there but the front is well developed. With backlighting this really glows. Hard to find good Illinois Fluorite of this color now except at very high prices. A good value for the quality, in person the color is a shade darker and a bit more blue than purple under most lighting.
A superb specimen with exceptional provenance. From the famed Vaux collection this specimen from the original find has a 1897 date on the reverse of the label. Lawsonite is a fairly rare mineral and these are huge crystals for the specie. This old find was also the source of the best Lawsonites ever found, and this specimen is superb, one of the very best. Vaux was a very selective collector
famed for his taste and care in selecting for his personal collection which was one of the best of his era. These Lawsonite crystals have sharp striated faces, choice luster, excellent blue color and reach 2 CM. I have only ever seen one specimen with larger crystals, it was the piece from the Roebling collection at the Smithsonian, but on this Vaux specimen the crystals are more perfect with better color and form. The matrix is mostly Glaucophane, in micaceous form, the whole specimen displays very well. Original handwritten Vaux label included which also notes this piece is 64.6 grams. An important piece, this is a true classic.
Olivenite, Conichalcite and Azurite
Christiana Mine, Lavrion District mines, Lavreatiki
Attiki Prefecture Laurion District,
3.5 x 3.1 x 2.4 CM (small miniature/ large thumbnail (toenail))
Olivenite in very well formed free standing crystals and radiating clusters are well protected in a colorful vug. The cavity is lined with bright blue Azurite prisms and surrounded by light green Conichalcite in discrete balls. In excellent condition, there is no damage found even with high magnification, and the color contrast is vivid. From the ancient locality of Laviron, one of the oldest known mining regions of Europe, this is a recently found (2012) specimen from the collection of Chris Spiromitros. Very impressive under magnification but also attractive as a small miniature display piece.
New Melones Spillway (Dam site), Calaveras County
4.3 x 3.2 x 1 CM (miniature)
A small, super clean matrix plate of perfect, gem clear Axinite crystals. A modern classic from the best find ever made in the USA. Close inspection shows very sharp glassy crystals with several habits many of which are free standing prisms. Smokey red-brown color with fine transparency. Ex collection of Brett Keller, a choice miniature.
A killer classic form of a "drill bit" twin crystal of Cinnabar stands out well on the Dolomite and Quartz matrix. In great condition, no damage and with bright luster, this glows a ruby red when backlit. The photos here do not have backlighting so the look is a bit darker but shows the twin form clearly. The Tongren Mine was a great locality for many years but is no longer producing. This piece is far better than average with a much larger than average crystal and very choice esthetics. At one time before China was opened for export of minerals a top Cinnabar like this was nearly impossible to obtain and close to priceless, being only available from museum collections. One of the great prizes in the mineral world, these are by far the best Cinnabars ever found and this is a super example.
A well formed pale yellow Sapphire crystal that is almost colorless with nice form and a sharp termination. The staggered growth steps on all six sides are very clear and distinct. This crystal is translucent and partly transparent with a very light frosting on the faces. A very nice textbook example of the specie from Mysore India, which is best known for Ruby Corundum, I have only ever seen a few non-red Corundum from this locality
A chantoyant "velvet" Malachite from the Shuli Mine, ex Shields and Frances Flynn collection. The Shuli Mine has on occasion produced some incredible Malachites that are rather like the best material from the Congo yet discernably different. Most good pieces tend to be large blocks, plates or masses, smaller cabinet specimens are quite uncommon. This is a perfectly complete undamaged early piece that is not huge and has the classic look of a fine Shuli Malachite.
A super single crystal thumbnail of red-orange Childrenite ex John Buckley Collection. This is translucent to transparent and has internal zoning. From a find many years ago at Mendes Pimental, there were very few found with this unusual color, it is possibly closer to the Eosphorite end of the series though the original testing called this Childrenite, we have not re analyzed this. Complete and well terminated, one part of the termination hosts a zone of tiny doubly terminated Quartz crystals which adds a nice contrast. No matter the specie this is a choice colorful example of both ends of the series.
