Siderite - gemmy crystals
stock #21.1-266-(B9)
Morro Velha Mine, Nova Lima, Iron Quadrangle
Minas Gerais, Brazil
6.1 x 4.3 x 3.1 CM (cabinet)
price: $160
Early summer 2021

Cluster of transparent to translucent Siderite crystals with stepped and modified Rhomb forms dominating. With backlighting this glows a deep honey-yellow color and is quite lustrous. In good shape overall there are some rough spots but none are major. The Siderite from this locale is some of the best in the world. The largest flattened rhomb on this piece is 3.1 CM across, and has sharply stepped faces.

Pyromorphite - US classic locale
stock #16.1-596
Pheonixville, Schuylkill Township, Chester County
Pennsylvania, United States
5.3 x 4.8 x 3.3 CM (cabinet)
price: $450
Early summer 2021

Two generations of Pyromorphite in several vugs and thin cavities on matrix. The larger crystals are the classic dark green that this locality is known for. The smaller crystals are a newer generation, more transparent, slender and a lighter yellow-green. By naked eye this is in excellent condition, with a loupe some damaged crystals are seen, but are not a major impact overall. A few small Calcites are also present. Some of the larger, darker crystals are also arranged in flat fan-like sprays while most are in more typical free standing form.

Shattuckite balls on Malachite crystals - NEW
stock #21.1-175
Okandawasi, Kaokoveld Plateau
Kunene Region, Namibia
4.6 x 3.3 x 2.6 CM (miniature)
price: $880
Early summer 2021

A super attractive miniature from a small new find. This piece was selected from just a few pieces that came out recently as it has just great form and presentation. Aside from that one small lot I have not seen any others before or since. The Shattuckite balls are both isolated and in small clusters. From some angles these look like berries on an evergreen tree. The Malachite is all primary crystals with sharp acicular form. In excellent condition, displays well from all sides. A great Copper secondary specimen that is really different.

SOLD Argyrodite with Pyrargyrite and Sphalerite
stock #SOLD 21.1-199
Gallofa Mine, Colquechaca, Chayanta Province
Potosi, Bolivia
4.2 x 3.6 x 1.6 CM (miniature)
price: $0
Early summer 2021

A hefty chunk of Silver ore with the Argyrodite in good masses and tiny crystals. Argyrodite is a quite uncommon Silver-Germanium Sulphide, only known in a few spots worldwide. A quite old specimen, there are previous collection numbers affixed. This is not a conventionally pretty piece, which is typical for the specie but it is a rich and rare chunk of this Silver specie. For many of us that can be beautiful!

Fluorite - modified gem clear cubes
stock #21.1-169
Xiayang, Yongchun County, Quanzhou Prefecture
Fujian Province, China
5.1 x 4.3 x 3.4 CM (cabinet)
price: $1050
Early summer 2021

From a recent (2021) find at Xiayang, a cluster of vivid purple-blue cubes on matrix. These cubes all have the beveled edge modifications that are perfect and sharp, a textbook example. Even more clear and lustrous in person. This sits on its own at several good display angles, the first photo is what some would call the back because there is less Fluorite present though I like the contrast. No matter the angle of display the prominent crystals are fully perfect as seen though some outer crystals do have some edge roughness or contacts. All in all the condition is fine. This does show some of the color change effect from incandescent to daylight or LED lighting. This is a special feature of some Fujian Fluorites and some have called it a "tanzanite effect". The shift from purple to blue is clear, though I must say not quite as vivid as on some other pieces. An excellent example of the find and just a nice Fluorite from anyplace.

stock #21.1-227
Dug Hill, Avant, Garland County
Arkansas, United States
6.5 x 3.8 x 2.4 CM (cabinet)
price: $330
Early summer 2021

Wavellite balls are well-formed with most of each sphere protruding out from the matrix. In excellent condition as seen, these balls under strong lighting have noticeable sparkle. Most spheres also have a good apple green color though a few show a whitish alteration in spots. An American classic, this is an excellent example, far better than typical and with balls up to 1.4 CM which is also much larger than typical. Wavellite is a fairly common Phosphate worldwide but these better Arkansas specimens are quite exceptional for the specie and most collectors agree these are the world's best.

Rutile - classic US locale
stock #10.1-327
Graves Mt., Lincoln Co.
Georgia, United States
3.2 x 2.3 x 1.7 CM (small miniature/ large thumbnail (toenail))
price: $230
Early summer 2021

Super sharp, highly lustrous and doubly terminated crystal from Graves Mountain. The front and sides of this piece are in excellent condition, perfect with no dings or chipping. The backside is contacted and has some adhering matrix which is not seen on display. The dark color (black to ultra dark red) is set off by a very bright metallic luster. This locality still gives up some fine crystals to dedicated collectors but much less than in the golden years of the late 1800's. This form and habit are really unlike other Rutile from anyplace else on earth.

Phosphophyllite - crystals in fossil clamshell cast.
stock #21.1-138
Huaylliani Phosphphyllite Diggings, Huayllani, Canutillas. Machacamarca,
Potosi, Bolivia
7.2 x 4.9 x 2.8 CM (cabinet)
price: $3800
Early summer 2021

Fine Phosphophyllite crystals nearly fill the void of a fossil clam shell with the center area still open. The center void has dozens of sharp terminations surrounding the middle. Some crystals show the classic "swallowtail" twinning habit and all are a translucent apple green. This is one of the very best specimens I have seen from a small find made in 2009-2010. Phosphophyllite in sizable crystals is rare and one of the "holy grail" species. Outside of Bolivia nearly all other specimens are quite small, measured in millimeters, and most are micros. This locality is about 45 KM from the more famous mines at Cerro Rico which is also in Potosi, Bolivia. The best specimens from Cerro Rico are highly prized, being both rare and some the most expensive mineral specimens in the world. This smaller find at Huaylliani more than a decade ago was huge news in the mineral world back then. While the crystals from here are not as gemmy and clear as the best from Potosi, they are still very fine and would rank as the second best in the world. The find is long ago finished and these are now quite prized as well. The largest crystals on this piece are over 2 CM but most are smaller. An unusual piece, very large for the area, this has both lustrous areas and some lightly frosted crystal faces. Minimal matrix, this is over 78 grams of nearly pure Phsopophyllite. The shape of the clam shell is still somewhat visible on the backside but the open vug of the green Phosphophyllite crystals is the real star here. In excellent condition overall, a few small Iron stains are present on some edges though the crystals are very clean. An outstanding piece from this important find.
