4.9 x 3.8 x 2.9 cm. Sharp, lustrous, battleship-gray, cuboctahedral galena crystals are richly and aesthetically scattered on all sides of the sculptural matrix consisting mostly of sparkly, brass-yellow pyrite microcrystals on this fine specimen from the Greystones Quarry of Cornwall. The Quarry is a modern operation worked for road metal. Strangely, galena is rare in crystallized specimens from Cornwall. Ex. Wesley Stark Collection.
3.2 x 1.5 x 1.4 cm. A really fine and aesthetic, two crystal specimen of splendent, compound, cuboctahedral galena crystals nicely attached to a bit of matrix from the famous mines at Naica, Mexcio. This piece is complete-all-around and is pristine. Classic material from the Jaime Bird Collection.
6.7 x 6.3 x 4.9 cm. A very complex, skeletal-growth galena crystal showing multiple overlapping habits of crystallization on one large crystal. This is a classic old Tri-State District piece, probably from the 1950s or 1960s. Ex. Harold Urish Collection.
4.8 x 4.0 x 3.0 cm. Water-clear, glassy anglesite blades to 1.0 cm are attractively set in a vug of massive, specular galena on this showy old-time piece from a classic Italian locality - Monteponi in Sardinia. Highly representative of the species and historic locale. Accompanied by an expertly handwritten, faded label from an older collection. The collection this came out of was a museum stash dating to prior to World War I.
5.2 x 3.6 x 3.1 cm. A striking, old-time galena specimen from the Tri-State District of Missouri and the Ed David Collection. A 2.8 cm, extremely elongated galena crystal dominates this very aesthetic cluster of lustrous, battleship-gray galena cubes. Elongated galena cubes of this habit are rare from the Tri-State District and this is an outstanding, complete-all-around cluster with only trivial contacting.
4.8 x 4.2 x 2.9 cm. An excellent example of the "fortification style" or galena epitaxial on galena. The brilliant, battleship-gray, second-generation, octahedral galena crystals encrust the large galena cube and give these totally incredible, maze-like patterns. The large octahedron on the right side is superbly hoppered. The front and all sides are pristine, with only the back being contacted. This classic, old-time and aesthetic galena specimen is from the historic Picher Field, Tri-State District, Kansas and the Feist Collection, # 3016. George assembled significant Tri-State and Viburnum Trend collections and this is an excellent example.
7.6 x 5.0 x 3.3 cm. interesting clusters of tiny, sharp, battleship-gray galena octahedrons are attractively scattered on both sides of the vuggy, sculptural matrix of solid cuprite on this excellent old-time specimen from the Dennis Mullane Bisbee Collection. The white areas on the photo are actually powder-blue chrysocolla, a colorful accent.
8.8 x 7.5 x 3.6 cm. A very fine and rich, two-sided calcite on galena specimen from the historic St. Andreasberg District of Germany. Glassy, colorless calcite crystals richly cover both sides of the sculptural, massive galena matrix. The calcite crystals have the classic shape and form of St. Andreasberg calcites. Old material dating to the 1800s and comes with an old handwritten label. Highly representative of the species and renowned locale.
9.8 x 7.0 x 4.8 cm. A superb, old-time example of the "fortification style" or galena epitaxial on galena from the famed Tri-State District. The battleship-gray, second-generation galena crystals preferentially encrust the large galena cube and give this totally incredible, herringbone pattern. Classic material from the George Feist Collection and from the much less well-known Chink Enders Mine, Picher, Oklahoma. A note on the former dealer label accompanying this specimen indicates that this piece came from an old Cornwall, England collection.
6.4 x 5.4 x 4.5 cm. A large and very sharp, euhedral Magnetite crystal on Galena and Chalcopyrite ore matrix. The Magnetite is an amazing 2.8 cm across, and has very good luster and beautiful complex form. This is a significant magnetite specimen for the species, for its bizarre complex crystal habit. In fact, it is quite remarkable that a well-formed Magnetite this size is in as good a condition as it is. Ex. Charlie Key Collection.
8.8 x 6.6 x 5.1 cm. A rare, rich and beautiful combination specimen from the Blanchard Mine. Scintillating, azure-blue linarite blades richly cover the sculptural quartz matrix on this fine, older specimen. The highlights of the piece, though, are the rare pseudomorphs of lustrous, gray cerussite after sharp galena cubes to 9 mm. The apple-green, brochantite needle sprays scattered about are a nice accent. Ex. Dennis Mullane Collection.
10.8 x 10.5 x 6.6 cm. A fine, upright, cabinet specimen covered with sharp, lustrous galena octahedrons from the Buick Mine of Missouri. The crystals reach 2.1 cm on this piece. This is classic, highly representative material from this noted locale but a large specimen in a quality you do not usually get for this heavy lead species. Ex. George Feist Collection # 2883.
8.4 x 6.4 x 5.1 cm. Four sharp, moderately lustrous, isolated galena octahedrons to 1.4 cm are aesthetically set on silicified limestone matrix dusted with ruby-jack sphalerite microcrystals on this classic, old-time specimen from Picher, Oklahoma. Ex. New York State Museum and George Feist Collection # 2939.
9.1 x 7.8 x 5.7 cm. Intergrown calcite and massive bustamite are the matrix for prismatic, flesh colored crystals to 7 cm across, and the piece weighs about 500 grams. Bustamite is an uncommon mineral species in crystal form known best from this locality (old workings, though) and from Franklin in New Jersey. Specimens from each appear similar. The calcite even fluoresces in each case. Here, though, the galena crystals embedded in the calcite matrix give it away as Broken Hill material.
5.1 x 4.3 x 4.0 cm. The Cerro Sapo area (the following is quoted from MINDAT) "is one of the few alkaline provinces in the Andes. The interesting minerals are from a large dike, 2km long, 1 - 5m wide, of pegmatitic ankerite-sodalite-barite carbonatite, which cuts a nepheline syenite intrusion and the surrounding hornfels and slate. Source of all the sodalite beads found in Inca and pre-Inca ruins ranging from Quito (Ecuador) to Tucuman (Argentina)." The mostly albite matrix is highlighted by blue sodalite and metallic-bright galena crystals, but this excellent combination specimen also contains the rare cerium carbonate, burbankite (reddish), plus brown ankerite and dawsonite and white hisingerite. Very representative and rare combination material from this uncommon locale. Ex. Wes Parker Collection.
