An old well formed and classic Blackdene Fluorite from the collection of Warren Johansson. Warren obtained this piece in an exchange with Harvard in 1938, so it is clearly a vintage specimen. The cubes reach 4.2 CM in diameter and have good sharp edges. Several crystals display internal cleavage planes but the exterior shapes are intact and in quite good condition. Minor edge wear is noted on the outside edges but the main crystals in the center are undamaged. The Galena is on the reverse side so will not be in any logical dispaly orientation.
From the famed Pseudomorph suite assembled by Ed Swoboda, this is a very odd but well formed piece. The identification was confirmed by the Smithsonian (as noted on the old label). The shape of the original Vivianite crystals is perfectly preserved and the exterior is overgrown with tiny clear Calcites that have bright luster. This is Carbonate Apatite and has replaced crystals up to 4 CM in size.
This quite attractive Psuedomorph has a lot of good provenance, ex Ed Swoboda, Carter Rich, George Loud, and William Hladyz. The shape of the large Aragonite crystals are sharply preserved and the color looks much like an Agate more so than Chalcydony. This is almost a perfect floater and despite a few very minor chips that are not easy to find the condition is still very fine overall. Classic older Pseudomorph not often available and rarely in anything close to this quality and esthetic.
Elmwood Mine, Carthage
7.1 x 6 x 1.9 CM (cabinet)
As simple gem-clear Calcite twin sits lightly connected to a flat limestone matrix. The Calcite shows zoning from Cognac to almost colorless. Sharp, perfect and incredibly lustrous. A small and quite affordable example of what has made Elmwood famous for world class Calcites! A second smaller Calcite is on the matrix that has a cleave on it, but it is hidden behind the main Calcite. Choice.
Broken Hill, Yancowinna County
New South Wales,
5.9 x 3.1 x 1.3 CM (cabinet)
A reticulated Cerussite from Broken Hill that has a small bit of green color included in some areas. Attractive and a bit different for the locale, this is not perfect on the outer edges but the main snowflake areas are quite fine.
Wulfenite with Mimetite crystals
Chah Milleh Mine, Anarak Dist., Nain Co.
Esfahan (Ishfahan) Province,
3.6 x 3.3 x 2.1 CM (miniature)
A cute small example of the Orange Wulfenite with small balls of Mimetite from the Chah Milleh discovery. An exciting new find of Wulfenite that has similarities to both the Rowley and San Francisco Mines, but is also clearly different. Those mines had little balls of Mimetite, but this has sharp prismatic crystals that look a bit like the orange Bunker Hill Pyros. For any Wulfenite suite this locality is quite important. Micro sized chipping exists (as in nearly every piece) shown in the photos. As a result this has a far lower cost but still looks good. Several crystal habits of both Wulfenite and Mimetite are seen with magnification, but the naked eye display is quite nice too.
Apatite on Quartz
Panasquieira Mines, Panasquiera Covilha
Castelo Branco District,
4.5 x 2 x 1.5 CM (miniature)
A very choice piece, this is a glass clear quartz crystal hosting several purple gem Apatites. The quartz is perfectly terminated, overall sharp and impressive in person, in very fine condition. Strong magnification reveals some tiny Siderite crystals. The Apatites have some slight zonation and have top luster. Not a typical Panasqueira specimen, and far more esthetic than average.
The Tongbei finds about 10 years ago produced a few excellent Fluorites in several colors and habits. When associated with Spessartine as is this example, it makes for nice esthetics. A good example here in fine condition, the Fluorite is an elongated octahedron and has clear zoning, slightly etched faces and is transparent.
