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 - $600
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

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.

Omaue Mine, Kaokoveld Plateau, Kunene Region, Namibia

Overall Size: 6 x 4 cm

Barite is an unusual mineral associated with dioptase from this locality and the two minerals provide a pleasing contrast of colors, plus such a specimen is the No. 1 spot for the association. The barite itself is 2.2 cm and surprisingly complete without damage.
