Bournonite, Quartz and Pyrite
stock #18-AX-10-906
Pachapaqui District, Bolognesi Province
Ancash Department, Peru
7.2 x 5.4 x 5.2 CM (cabinet)
price: $280
Late Summer 2018

Two-sided specimen with excellent sharp Bournonites on both sides. All the Bournonites show bright silver luster and twinning that in some crystals has the classic cogswheel habit. The side I consider the "front" or better display side has two main Bournonites that are perfectly formed and undamaged, set off by golden Pyrite and milky Quartz crystals. The "back" side has more nice Bournonites but there is some damage and contacts, (that is why it is the back of course). A few years ago matrix Bournonites of this quality were very rare and expensive when available but both China and Peru then began to produce these and they became very affordable. Now both these sources are not producing.
Wardite -huge crystals with Wavellite etc.
stock #18.1-360
Ilha claim, Taquaral, Itinga
Minas Gerais, Brazil
6.1 x 5.9 x 4.5 CM (cabinet)
price: $850
Late Summer 2018

A superb specimen with gigantic, perfectly formed Wardite crystals. Textbook perfect form and up to 2 CM across these are the best and largest Brazilian Wardites I have ever seen, and are top percentile for the specie worldwide. These are esthetically set on a complex mix of Pegmatitic minerals and Phosphates. Aside from the Quartz and Muscovite crystals the matrix also includes what are identified as Wavelite (radiating sprays and blue green balls) and what seems to be Fairfieldite and Guimaraesite. The main event however is certainly the Wardites which are a cream color and undamaged. Outstanding Phosphate specimen and a killer Wardite.
Anadalusite in Sericite Shist
stock #18-AX 35-159
Cargo Muchacho Mountains, Imperial County
California, United States
5.7 x 3.9 x 3.1 CM (cabinet)
price: $300
Late Summer 2018

Something a bit unusual, the main Andalusite crystal is well-formed and over 3.5 CM across. Nice overall composition, the biggest Andalusite is quite well exposed from the Schist. Ex S. Alverson collection, this was collected in 1980, but not at any of the noted mines, just a small prospect. Microscopic exam finds many Hematite crystals and one Kyanite in the matrix as well. A fine, less common California specimen and a nice prismatic crystal of Andalusite.
Fluorite
stock #15.1-1069-(SM4754)
Fort Wayne. Allen County
Indiana, United States
4.3 x 3 x 3 CM (miniature)
price: $280
Late Summer 2018

A pretty mid-western US Fluorite with transparent crystals that are far more clear in person. Overall sharp and lustrous there are some small edge jagged zones that with strong magnification appear to be mostly natural contacts and a few partially recrystallized bruises. One tiny cleave is noted too, so this is not perfect but by naked eye it still looks quite fine, has great color and displays well. Ex Charles Noll collection, vintage 1970 time period. Crystals to 2.5 CM, the matrix is clearly seen through the cubes.
