D-Block Mine, Merelani Hills, Simanjiro District, Manyara Region, Tanzania

Elizabeth R. Mine, Pala District, San Diego Co., California

This entire specimen is just plain pretty and easy on the eyes. On the prisms of this specimen are beveled faces, several of them against another, to create a sort of staircase specimen. The crystals are peachy pink and translucently clear, with its core slightly more opaque. This morganite, an all-time California classic, is pristine without repair and comes from a find in 2005 from the Elizabeth R. Mine.

S18444 - Diopside - $750
Chamachhu, Haramosh Mts., Skardu District, Gilgit-Baltistan, Pakistan

Overall Size: 6 x 2.2 cm

This specimen resembles high-quality alpine epidote, and the interior glows a rarer shade of green similar to old Knappenwand. Their doubly terminated ends and parallel growth is often arranged in similar fashion, with crystals in a clearly defined natural mold and gem state. The glassy faces of these prisms is especially noteworthy.

M'fouati Mine, M'fouati District, Bouenza Department, Republic of Congo

S18460 - Spessartine - $100
Marienfluss, Kunene Region, Namibia

Overall Size: 3.6 x 3 cm

This tangerine-orange spessartine is stunning, and the small but bright crystals sit situated all over the piece. This garnet is highly representative and likely to be a perfect fit.

S18462 - Rhodonite - $5000
Morro da Mina Mine, Conselheiro Lafaiete, Minas Gerais, Brazil

Overall Size: 8.6 x 5.2 cm

This Mn-rich skarn produced some of the nicest rhodonites around when miners started to uncover a jump in quality in the mid-2000s from the Morro da Mina mine in Brazil. The finest crystals are much larger than any previous worldwide finds, which collectors admire so much, and on a scale of deep red color they are perhaps even more saturated. This specimen is roughly diamond shaped, strikingly large at 8.6 cm in contrast to notably white colored matrix. This is, for the collector, such a cresting crystal of an attractive rarity.

S18465 - Azurite with Arsentsumebite - Price on Request
Tsumeb Mine, Tsumeb, Otjikoto Region, Namibia

Overall Size: 9.2 x 6.3 cm

This matrix of arsentsumebite, which features lively apple-green color, is full of tiny twinned crystals in striking contrast to azurite, and this combination is one of the most famous and attractive from Tsumeb, and justly so. They make magnificent display specimens and only come from Tsumeb, with an ultimate showing of dramatic color contrast. When placed in a case next to other specimens it really has overwhelming POP and GLOW by comparison.

S18467 - Quartz (Var. Amethyst) with Epidote - SOLD
Las Vigas, Veracruz, Mexico

Overall Size: 8 x 4.4 cm

This is an outstanding amethyst of exceptional clarity and pleasing grape-purple hue. As important as that is, it needs more to make the piece stand out, and that would be a distinct style of long sceptered amethyst towering above matrix. This specimen is incredibly pristine and complete all around.

S18470 - Lazulite with Siderite - $150
Rapid Creek, Dawson Mining District, Yukon Territory, Canada

Overall Size: 7.6 x 5 cm

This specimen of lazulite is balanced, with consistent glasslike luster. The bright azure-blue cluster of crystals to 2.6 cm are not interlocking too much as is usually the case, and a true cluster in contrast to lustrous siderite pops more effectively.

S18472 - Fluorite with Chalcopyrite and Galena - $750
Slitt Vein, Blackdene Mine, Weardale, North Pennines, Co., Durham, England

Overall Size: 11 x 7.5 cm

An important and classy specimen from an old and classic English locality that is now closed. The Blackdene mine started mining operations in 1401. However, this piece came out in the early 1970s. This association is exceptional and from here in particular, with such crystallization of brassy chalcopyrite clustered atop fluorite. The piece comes with previous owners labels.

N'Chwaning II Mine, Kalahari Manganese Fields, Northern Cape Province, South Africa
