Dolomite with Quartz
Traversella, Chiusella Valley, Canavese DistrictMetropolitan city of Tur
5.3 x 3.5 x 2.4 CM (cabinet)
A cute and unusual Dolomite that is in translucent blocky rhombs nestled with clear Quartz crystals. A vintage specimen with old labels ex Pallanza collection. Very good luster and condition, Dolomites from this area of the Piedmont are known in many habits and styles, this one look much more like a French Alpine specimen but is really from the Piedmont.
Bright lustrous Epidote crystals in a cluster that are topped with a larger compound prism on the top. Largest prisms reach 1 CM which is very large for this locale. The crystals are all gemmy and the largest are in fine condition, a 20X magnification finds some very tiny chips but perfect by naked eye. The Bellacombe area is one of the great classic locales best known for great Garnets, Vesuvianites etc. The Epidote here can be a bright yellow color when small and grades to a honey brown as they get larger. This is a nice example that is well above average for size and esthetics.
A super sharp, clear and lustrous gemmy Adularia crystal is nicely perched on matrix. A very old specimen, ex Roberto Palumbo (Rome, Italy mineral dealer active 1928-1945) with his label. The Feldspar is distinctly twinned as well and perfcely undamaged even at high magnifications. The locality of Monte Forno in the Piedmont has several well known alpine localities on it but also many tiny clefts that were worked mostly by Swiss Strahlers over a very long period. This is a choice piece with the Adularia well above the matrix and presenting well from all sides.
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.
Choice Val Malenco Garnet specimen with several waxy green rounded Demantoid crystals perched on typical Amphibole matrix. The elongation of the 2.1 CM main crystal is impressive, and shows complex rounded faces. Classic specimen, these have always been prized and this is an older piece, sawn on the back as is common to enable collecting intact. The matrix has some cracks that may be old repairs or typical weakness in the fibrous structure of the matrix. Well above average quality best appreciated in person
An old Italian specimen that is loaded with several well crystallized rarities. Included older labels have misidentified the Metastibnite as Kermesite which it does indeed look like. Aside from that, this hosts well developed crystals of Klebelsbergite in several forms, Peretaite, Sulphur, Stibnite, Valentinite and possibly Ottensite and Minyulite. A real treat under the microscope, but the largest metastibnite crystal is 2.8 CM and needs no magnification.
A very good matrix Garnet specimen with the classic style of Piedmont region Grossular. The crystals are sharp and translucent- a deep red when backlit but with normal lighting (as in these photos) typically look darker, almost black. In excellent condition a very good locality piece with bright luster.
