A very large, vividly fluorescent and nicely zoned Phosgenite crystal dominates the sizable matrix. Other areas of Phosgenite are noted on the piece but the main crystal is 4.6 CM across and presents well. What may be an old repair is noted, if so it is not affected by acetone testing and may be a natural crack. Much of the crystal is transparent to translucent and has the classic flat morphology noted from this ancient locale. Even if repaired (the price assumes this is so and is adjusted) this is a choice example and has a very nice presentation. This could also be trimmed to a killer miniature but that would remove many vugs of smaller crystals so we have left this intact. Ex Ara Dildilian and William Haladyz collections, clearly a very old piece.
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 Ducessa Mine, Oridda, Carbonia-Iglesias Prov.
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 inclusion 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 catagory 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!
