AU572 - Arsenopyrite, Siderite, Chlorite $ 250 Panasquiera, Castelo Branco, Portugal miniature - 5 x 5 x 3 cm Bright silvery metallic crystals of Arsenopyrite, tabular tan Siderite, and green Chlorite over unidentified crystals all combine to form one heck of a pretty specimen. This is one of those pieces where the closer you look, the more you like it. Ex. Angela Cannon collection.
AU573 - Cerussite $ 250 Mammoth Mine, Tiger, Arizona, USA thumbnail - 2.3 x 1.9 x 1.8 cm Glassy, complete V-twin crystal of Cerussite from Tiger. Comes with an old label from the Sterling Hill Mining Museum.
AU574 - Galena on Quartz with Chlorite $ 2500 Madan, Rhodope Mtns., Bulgaria small cabinet - 9 x 7 x 5.5 cm Stunning specimen of Galena on Quartz crystals with small green blebs of Chlorite mixed among the Quartz. The Galena is really fantastic, with the appearance of polished chrome - it's just amazingly bright and lustrous. The main crystal is 4cm in size and fronted by a large Quartz crystal. The main Galena crystal consists of an earlier generation of Galena that was coated by Chlorite and followed by later generations of Galena, forming an interesting, complex shape.
AU576 - Grossular $ 500 Handan Pref., Hebei Prov., China small cabinet - 5.5 x 5 x 4 cm Large cluster of nothing but interconnected, gemmy Grossular garnet crystals. The crystals are an amber/yellow color and transluscent to transparent. Average crystal size is about 5mm to 1cm with the best crystal at 1.5cm. A good sized cluster for the find. There are a few contacts where this cluster grew against other garnet crystals, but the majority is clean undamaged crystals.
AU577 - Veszelyite on Plancheite $ 1600 Kipushi Mine, Kipushi, Katanga, DR Congo miniature - 4 x 3.5 x 3 cm Sharp, isolated crystals of translucent Veszelyite spinkled across the surface of velvety sky blue Plancheite. This is an old specimen, likely from the 80s or 90s, that I've owned for about 25 years. The Velzelyite form sharp, distinct individual crystals to 3mm in size. There is an old collection number painted on the bottom that was there when I bought it.
AU578 - Spinel $ 600 Mahenge, Morogoro, Tanzania miniature - 4.3 x 4.2 x 2.5 cm Large, translucent reddish pink single Spinel crystal with some light green Pargasite attached to the back. Tall undamaged crystal with complex form.

Interesting combo piece for this locality.
AU582 - Malachite after Azurite $ 600 Milpillas Mine, Cuitaca, Sonora, Mexico small cabinet - 7 x 4 x 3.5 cm Exceptionally sharp, velvety pseudomorphs of Malachite after Azurite from the Milpillas Mine. These pseudomrophs from Milpillas are excellent, and there have been a good number produced over the years, but this one has the most well formed, crisp sharp crystals I've yet seen.
AU583 - Franklinite $ 400 Franklin, Sussex Co., New Jersey, USA small cabinet - 8.5 x 8 x 4 cm Black Franklinite crystals to over to 3cm in matrix. The largest crystal has a fracture that has possibly been repaired. The large crystals are in a matrix of white Calcite, orange Willemite, and smaller Franklinite crystals. The Willemite are bright green under fluorescent lighting.
AU584 - Molybdenite $ 350 Wolfram Camp Mine, Queensland, Australia small cabinet - 7.5 x 4.5 x 3 cm A sharp 2.5cm single Molybdenite crystal in crystalline white Quartz. A perfect single hexagon, which is less common for this locality as compared to the more typical thick aggregates of crystals. This could be trimmed down to a fine miniature.
AU586 - Copper $ 250 Poteryaevskoe Mine, Rubtsovskoe Deposit, Western Siberia, Russia miniature - 3.3 x 2 x 1.2 cm Well crystallized Copper specimen from Russia with a superb tall single crystal rising up in the center. Sharply formed crystals all around.

AU588 - Boracite $ 450 Boulby Potash Mine, Loftus, Cleveland, England miniature - 4.5 x 3.5 x 1.3 cm Bright, sparkling crystals of blue Boracite on the front and back of specimen. The crystals are good sized reaching 4mm in diameter. Colorful and rich example of essentially nothing but Boracite crystals.
AU589 - Tremolite $ 950 Merelani Hills, Arusha, Tanzania miniature - 4.8 x 2.7 x 1.1 cm Large single green Tremolite crystal from the Merelani Tanzanite mines. This is a big one with a smooth, flat termination face and typical splintery edges. Gemmy with superb, vivid green coloration. These are only occassionally found and usually in smaller sizes - at nearly 5cm tall this is much bigger than most. I have seen some longer than 4.8cm, but they are usually thinner crystals - this one is thick and robust.
AU594 - Amethyst $ 400 Las Vigas, Vera Cruz, Mexico cabinet - 10 x 8.5 x 6 cm Colorful, fine quality Amethyst specimen from Las Vigas. The Amethyst occur on a highly textured matrix colored green by coatings of Epidote that creates a great color contrast against the deep purple Amethyst. The Amethyst are mostly doubly-terminated, undamaged, and highly transparent. The largest crystal is 3.3cm long. Great specimen that's a little different looking than your average Las Vigas Amethyst.
