Heulandite - historic, ex Robert Ferguson
stock #1078-JM-3710
Teigarhorn, Berufjordur, Suour Mulasysia
Suour Mulasysla, Iceland
8.8 x 7 x 3.7 CM (cabinet)
price: $140
Early summer 2021

Heulandite crystals in a pinkish Natrolite vug from the famed collection of Robert Ferguson (1767-1840). This was obtained by John Marshall in 1998 when the collection was rediscovered and sold-off in lots. This piece, like many others, does not have a label, so some details are lost, but the collection lists pieces from Berufjordur so this given locality is a speculation. However this seems very likely as this matches specimens from here very well, and Heulandite was a new mineral in the years that Ferguson was actively collecting. Crystals reach 1.7 CM and are the typical sharp, glassy partly transparent type well-known from this region of Iceland. Some penetration twins of the prisms are distinctive. No damage.

Azurite stalactites with Malachite and Hematite
stock #20.FC-119
M Ssici, Ainif County, Tinghir Province
Draa-Tafilalet Region, Morocco
10.4 x 6.4 x 6.3 CM (cabinet)
price: $1650
Early summer 2021

Incredible color and esthetics from the amazing find of 2010 at M'Ssici (Morocco). Since then only a small find in 2017 produced any specimens those with a very different habit. This cluster of stalactitic growths is encased by small sparkling crystals and rosettes of bright blue Azurite with some small Malachite balls. The matrix is a mix of green Malachite and red Hematite gossan. The Malachite is replacing textbook sharp Azurite crystals and rosettes. Excellent condition, the blue stalactites are standing up to 5.5 CM tall above the green. This locality produced many specimens of Azurite encrusting Quartz crystals but very few pure (hollow) stalactites where there is no inner Quartz crystal. In terms of color intensity, form and condition this is one of the best pieces and is far better in person.

Adamite - gemmy balls
stock #10.1-172
Mina Ojuela, Mapimi
Durango, Mexico
5.3 x 4.3 x 2.5 CM (cabinet)
price: $330
Early summer 2021

Lustrous green spherical clusters of Adamite crystals contrasting with a dark gossan matrix. An esthetic yet affordable Adamite, this is also intensely fluorescent. Adamites have been found for decades at Mina Ojuela and are common in the mineral market. Good complete balls are much more rare and the vivid green is especially choice. These balls are translucent to transparent, glassy, apple green and have a "wet-look" luster. A choice piece and better in person.

Spessartine on Smoky Quartz
stock #20.1-204
Tongbei, Yunxiao County, Zhangzhou Prefecture
Fujian Province, China
7.7 x 3.4 x 3.1 CM (cabinet)
price: $490
Early summer 2021

Bright orange-red Spessartines on all sides of a single Quartz crystal. A modern classic from Tongbei (China); when first found these were huge mineral news, unlike anything else known before. For a few years ago these were fairly common in the mineral market but as the zone became exhausted there are almost none found now. The prices have also been increasing. This specimen has larger than typical Garnets with the crystals reaching to 7 mm. Excellent condition and esthetics, the color and luster are a bit brighter in person.

Fluorite - highly etched spires
stock #21.1-070
Omehane, Otjinamewa, Dâures
Erongo Region, Namibia
3.5 x 2.3 x 1.7 CM (small miniature/ large thumbnail (toenail))
price: $480
Early summer 2021

Very unusual, highly etched yellow Fluorite from a little known locality in the Erongo Region of Namibia. This was from a small find of just 6 pieces, all with good yellow color (unusual in Namibia) that have been etched into spires. This piece and all the others are nearly pure Fluorite but with a thin band of crystalline Quartz that is the base. We have been hoping to obtain more of these odd Fluorites but nothing else of this sort has been produced. A very different looking (and oddly attractive) piece that will not be like anything else in a Fluorite suite.

Copper with Malachite and Analcime
stock #16.1-450-(CN4044)
Cliff Mine, Pheonix, Keweenaw County
Michigan, United States
6.9 x 5.8 x 5.9 (cabinet)
price: $1250
Early summer 2021

A cluster of Copper crystals of many sizes, most being complex dodecahedrons. Malachite encrusts the Copper making a great color contrast. Scattered small Analcime crystals, a few of which are transparent, add a further contrast. An older specimen, ex. Charles M. Noll collection, this displays well from any angle. Close exam shows the smallest Copper crystals are super sharp, textbook perfect nestled between the medium and large sized crystals that are a little more crude though still distinct. A fine Michigan Copper that is a bit different and is especially showy in person.

Calcite - Hematite included
stock #13.1-199
Santa Eulalia, Aquiles Serdan
Chihuahua, Mexico
12.8 x 7.4 x 2.7 CM (cabinet)
price: $220
Early summer 2021

Glassy, clear Calcite crystals in excellent condition are partially included by red Hematite. These were found some years ago at Santa Eulalia, the crystals are transparent to translucent and the Hematite inclusions are cloud-like zones inside. No visible damage, this is a choice Mexican specimen that is similar to very fine specimen of the famed English classics, but far more affordable. Better in person too.

Paravauxite and Wavellite on Quartz
stock #20.FC-007-(9086)
Siglo XX mine, Llallagua, Bustillos Province
Potosi, Bolivia
10.4 x 7.3 x 4.3 CM (cabinet)
price: $1450
Early summer 2021

A superb large cabinet specimen of very fine aesthetic composition. A plate of Quartz crystals are entirely encrusted with tiny sparkling prisms of clear Paravauxite and a few scattered balls of Wavellite. In fantastic condition as seen, this is a very rich specimen of these two Phosphates and has a subtle creamy yellow to greenish tint best seen in person. The balls of Wavellite reach 1.5 CM and are composed of creamy radiating crystals with a pearly luster. The Paravauxite crystals are more equant prisms than the typical flat habit, the luster and transparency is excellent. Though those crystals are small the overall display impact and three dimensional architecture is superb for the specie.
