A single crystal of Phosgenite from the classic Monteponi Mine, ex Delaware University museum and attributed to the George Kunz collection (No Kunz label but a faded number on the specimen). Most of the Phosgenites from this locale have some type of damage, this one has some edge wear but is mostly complete on all sides, there is a chip on the backside and an old repair to note but still shows the form very well. This has classic flat basal terminations and stepped outer edges on the prism faces. Gemmy areas as well as vivid fluorescence add interest and character. For many years the Monteponi Mines were the world's best source of crystalized Lead secondary minerals like this; they are still prized and respected today.
Choice, quite lustrous green Pyromorphite (originally labeled as Mimetite) from the old locality at Donori, Sardinia. Very good coverage and deep apple green color, a few small crude crystals are seen with strong magnification, but overall this is a botryoidal specimen. Quite three dimensional and in fine condition, this is much richer than most I have seen from the locality. These are now often labelled as being Pyromorphite- Mimetites as it seems there are both species in the deposit and may be zoned.
Calcite & Quartz (Cumberland habit)
Sa Duchessa Mine, Oridda Valley, Domusnovas, South Sardinia Province
5 x 3.7 x 3 CM (miniature)
pre Tucson 2015 update
An odd yet attractive very old Sardinian Calcite specimen with a second generation of Quartz in "Cumberland habit". The Quartz also has numerous inclusions and some is in stacked groupings. There is considerable Hematite on and in many crystals here, adding nice color contrast. In good condition and attractive, most everything is doubly terminated.
An older, well-formed amber colored Barite from the Sulcis area of Caligari in Sardinia. Ex. Mineral Gallery (K. Ward) This shows several good phantoms with backlighting, and has a second generation overgrowth in some areas. Over all in fairly good condition there is contacting on one side and at the rear, small edge chipping is present but not easily seen from the logical display angle. A nice, good color piece from a classic local with the main crystal reaching 4.8 CM.
Monteponi Mine, Iglesias, Carbonia
4.4 x 2.8 CM (miniature)
A real prize winning miniature! (First Prize miniature category at MTL Mineral EXPO). It is impressive, esthetic gemmy and has classic form, from the most classic locality, Monteponi. An older specimen from this long closed mine, it is composed of 3 main intersecting crystals. Close exam finds very minor chipping mostly just on the base and backside, it can be displayed "eye clean". For this delicate mineral it is "virtually perfect". From an older collection, this quality is simply not for sale today. An older collection number is on the reverse side, it can be removed if that side is to be displayed. Choice!
