Pyrite with Dolomite
stock #0725-JM-2882
Niccioleta Mine, Massa Maratima, Grosseto Province
Tuscany, Italy
9.6 x 9.5 x 4.2 CM (cabinet)
price: $300


A fine and well-developed cluster of Pyrite crystals showing deep striations and bright luster. Ex John Marshall collection, this is a vintage piece from a locality we rarely see, but which was famed for fine Pyrite crystals and some other Sulphides (Stibnite etc). In excellent condition the Pyrites are in clusters and also in well-isolated crystals. This is a solid and stable piece there is no sign of any degeneration or oxidation.

Klebelsbergite on Stibiconite with Stibnite, Quartz etc.
stock #17.1-415
Pereta Mine, Scansano, Grosseto Province
Tuscany, Italy
7.2 x 5.5 x 3.8 CM (cabinet)
price: $330
Late Summer 2021

Three dimensional vuggy matrix with several altered Stibnite crystals that are now the matrix for blood red Klebelsbergite crystals. There are also some sprays of colorless needles and small yellow balls that are not identified though we suspect the needles are also Klebelsbergite. Most specimens of this mineral are micromounts and not so well visible as this. The crystals of Stibnite/ Stibiconite reach to a little over 3 CM long and are well-protected in the vugs. Ex collection of Glenn Petrie and Brizzi Gioncarlo (Florence, Italy). The older labels mention Kermesite which is not known from this locality. I can not see anything that looks like this specie and suspect it is an error, but it could be possible in tiny crystals. . The Pereta Mine is not well-known outside of Italy but it is an important and rich old locale that has been the source of many rare Antimony minerals. This is a rich example of several alterations of Stibnite and while very impressive under magnification it is also attractive as a normal, eye visible display specimen.

Grossular var. Hessonite (classic locale)
stock #21.1-198
Ala Valley, Lanzo Valley, Turin
Piedmont, Italy
5.8 x 3.4 x 1.3 CM (cabinet)
price: $650
Early summer 2021

A plate of highly lustrous Garnets from the famed Ala Valley. The color and transparency of these Grossular is outstanding. There are several larger, more isolated crystals that are set in a matrix of much smaller Grossular. The larger crystals reach 1 CM and glow a vivid red when backlit. In normal lighting the color is darker red as seen in the photos. This is a particularly rich piece with a fine color and dense coverage of bright sparkling Garnet. Overall in very good condition, some rough spots are seen with magnification but these are very minor and almost invisible in the context of the piece. Far better than average esthetics and visual impact from the Piedmont region.

Celestite (Barian Celestine)
stock #AC-313
Girgenti
Sicily, Italy
9.7 x 7.2 CM (cabinet)
price: $325
Early summer 2021

A beautiful glassy spray of powder blue crystals radiating upward from a massive base. This is a very old specimen from the classic Sulfur locality that has been mined for many centuries. This type of Celestite with the blue color has sometimes been labeled as Barite but often on analysis is found to be Celestite with some Barium. The piece is attractive despite chips and damage to a few crystals. Very uncommon to find material this attractive on the market, the blue color is especially desirable.

Phosgenite - vintage, classic locale
stock #17.1-854
Gibbas Mine, Villaputzu
South Sardinia Province, Italy
7.1 x 6.6 x 6.5 CM (cabinet)
price: $880
Early summer 2021

A rare specimen of Phosgenite from the Gibbas Mine of South Sardinia. This mine was active in 1851-1882 and flooded by 1890. Phosgenite is a rather uncommon Lead Chloride but specimens from this famous old locale are super rare (there are none on Mindat). Several milky white Phosgenite crystals from 1 to 2 CM across are clustered in a vug of altered Galena. This piece comes from the remarkable collection of Ruth and Andy Palmer and later William Hladysz. This was the study collection for Dr. Joe Mandarino's work and held many unusual and rare locality specimens. The Phosgenites are vividly fluorescent and are well-formed with a thin surface alteration. This is the only example from this location I have seen outside of a museum and is a quite a nice Phosgenite.

Hemimorphite - intense blue
stock #21.1-009
Sa Duchessa Mine, Oridda Valley, Domusnovas, South Sardinia Province
Sardinia, Italy
4.2 x 2.7 x 1.7 CM (miniature)
price: $180
new year 2021

A small but vivid blue Hemimorphite with a sparkling luster from the classic Sa Ducessa Mine. In fine condition save at the outer edge where this was removed the display side is perfect and undamaged. This is a fairly old specimen (over 25 years at minimum) and since the color is still excellent it seems to be fully color stable. The deeper blue grades to a lighter powder blue on some of the botryoids. Unlike the recent fake Hemimorphites from Mexico which were a darker blue this is full natural and a nice example from this famed locale.

Demantoid (Andradite) - vintage classic garnet
stock #20.1-616
Val Malenco, Sondrio Province
Lombardy, Italy
6.3 x 5.2 x 2.7 CM (cabinet)
price: $370
new year 2021

A chain of linked line of apple-green Garnets on a Rodingite/Serpentine matrix. The specimen is from the old locality of Val Malenco and was collected prior to 1905. The form and color of these Andradites are classic and immediately recognizable. In very good condition as seen, just one very small chip is noted, the crystals reach up to 1.3 CM in a 4.7 CM line. The luster is waxy and the crystals are all transparent to translucent. In person the color is close to a good deep Peridot hue.

Carnelian - red Quartz nodule
stock #1047-JM-1645
Fassa, Val de Fassa, Trentino -Alto Adige
South Tyrol, Italy
4.6 x 4.3 x 2.8 CM (miniature)
price: $360
new year 2021

A half nodule of bright red Quartz (crypto-crystaline variety Carnelian) from Fassa which is now in Italy (since 1919) but at the time this was found was in Austria. From the Phil Scalisi collection and also was in the John Marshall collection Translucent to transparent, an excellent example of an old European Carnelian gem that is just not often seen for sale.
