An extraordinary, sharp and brilliant Chalcopyrite from the classic Creede district. Chalcopyrite is a delicate, brittle mineral that rarely survives without damage, it is quite rare to find really good crystal specimens. This is a very fine example with rich patina and form, individual crystals reach 2.2 CM and the overall condition is outstanding, no eye visible damage! Fine piece for the locality and for the specie.
Cinnabar on Dolomite
stock #7 CNA 522
Chatian Mine, Fenghuang
6.5 x 5 CM (small cabinet/ large miniature)
A very fine gemmy 1.3 cm main crystal of Cinnabar sits well in an exposed vug of crystallized Dolomite. It is rare to find this form, tabular and untwinned in any but micro crystals. The color is the richest possible red and is in good condition. Close examination shows a hairline crack in the prism but it seems solid and does not detract at all. This is far above the usual quality!
A very old, classic European location piece, presenting some good sharp bundles of stacked Pyrrhotite crystals. The original label says "pyrrhotite and marcasite" the latter is not evident. John Marshall's note says "where is the marcasite?" Wherever it is or went, the piece has a great pedigree with reasonable cost. These are very rare in any form today.
Impossibly bright and lustrous, these modified cubes make a very eyecatching specimen. The fantastic Bulgarian Galenas are already noted as some of the best ever found. There are many forms and associations, but the most impressive are those with an intense metallic luster that is almost impossible to photograph. Damage free, this is a great value.
Lake George, Park County
7.2 x 5.9 CM (cabinet)
Sharply crystallized and with excellent color, this is a good Colorado Amazonite. Without damage and with good esthetics, this is an affordable specimen from a classic location.
A 10 CM, doubly terminated gemmy quartz crystal showing parallel growth is host to a rich display of Eosphorite crystals. No damage, the Eosphorite blades are in radiating clusters that reach up to 1.7 cm. Ex John Marshall collection, he obtained this piece in the 1970's. Good Eosphorites are uncommon, and this is an exceptionally fine one.
An exceptional Mexican specimen, a fine example of the specie and this uncommon form. This is the very best specimen of this sort I have seen. Bright sparkling spheres in a chain arrangement are contrasted by the quartz crystals. Damage free, with strong esthetics (it could be trimmed to a smaller matrix but I prefer the current form) this is a fine and rare example from Guanajuato. Ex John Marshall collection.
An unusual Beryl crystal, from a find several years ago (1960's) that produced these odd specimens. Bright glassy luster, a deep translucent bluish white zone at the base changes to a clear blue green near the termination. There is micro chipping on some edges, as all pieces had from this find, despite this the specimen is the most pristine I have seen of this style. A very different Beryl that is certainly rare!
