Cerussite - gemmy sixling
3.5 x 2.6 x 2.1 CM (miniature)
new year 2021
Small but sharp, brilliant, transparent Cerussite crystals from Tsumeb. A super specimen in person, ex Willy Israel collection which he obtained from Clive Queit. This is a reticulated sixling habit where one arm is much larger than the others. The luster and inner reflections are difficult to see in photos but the color and light refraction of gem Cerussite is well seen in person with this piece. Nearly perfect, magnification shows some small inobtrusive chips but for this famously fragile and delicate mineral the condition is really fine.
A choice old Tilly Foster (USA) Chondrodite specimen. Several dark red Chondrodite crystals up to 1.3 CM stand on a matrix of Chondrodite and crystallized Clinochlore. This is from the important early collection of Wallace Gould Levison. His collection ledger notes he obtained this on May 9th, 1897 on a trip to the mine, purchased from a Mathew McClosky, we presume to be a miner. A copy of this ledger page is included. Some contacting and small chips are noted but the condition is still much better than typical. Tilly Foster specimens are highly sought after classics, hard to find in any quality, this piece has the very rare addition of a clear early provenance.
A fine classic French specimen of gemmy Dauphine habit Quartz decorated with Siderites that are partly to fully pseudomorphed. The Siderites retain the flattened rhomb form perfectly and some are actually "skewered" on the slender Quartz. In excellent condition only one Quartz on the edge has any damage and that is not evident on display. Remarkable that this size and delicacy is intact. This was in the collection of William Hladysz for many years, he obtained this from Carter Rich. Carter's label gives some contradictory locality information, he lists La Mure, Bourg de Oisans and Vizille on the label, but these are really separate locales, all in Isere. This is clearly from Isere but almost certainly from Allevard. Siderite of this sort is not typical of Bourg de Oisans although the Quartz is. The Allevard locality in the same region is assured by our French colleagues as accurate, they know the zone well. Overall a very impressive display piece of classic Alpine minerals from this famed zone above Grenoble. Choice specimens like this are almost never seen for sale, especially in the USA.
A very clear, fully transparent Fluorite is nicely perched on a mineral-rich matrix that includes clusters of Austinite and bright green Cu Austinite. This Fluorite has the rare vivid bright red fluorescence which is quite unusual for the mineral from any other find. Also rather unusual is this Fluorite has smooth, glassy transparent faces, this is very rare at Ojuela where most Fluorite has stepped faces and is more translucent than transparent. A super esthetic miniature this is in perfect undamaged condition by naked eye, it takes a 20X magnification to reveal a tiny bruise. Way better in person and the UV response is as good as I have ever seen.
Ludlamite - classic USA locale
Blackbird Mine, Lemhi County
3.9 x 3 x .9 CM (miniature)
new year 2021
A small miniature plate sprinkled with many sharp yellow-green Ludlamite crystals and tiny Pyrites as well. An older specimen from the Blackbird Mine (Idaho) with a label from Dawson's Minerals (California) dealership from the 1961-1979 era. In fine condition the tiny Ludlamites are gemmy and look great under magnification. An affordable example.
Very attractive and very unusual Smithsonite from Tsumeb. These rhomb crystals are clustered but still well isolated, transparent and mostly colorless. However the incredible detail is these have an orange core, a distinct phantom that is clearly seen inside many of the crystals. In fine condition, this would be a nice addition to any Tsumeb or Smithsonite suite, it is really different. The Smithsonite is perched on a Sulphide matrix with etched Galena and some Pyrite forming a solid base.
A historic specimen from Sala in Sweden the type locality of Salite, which is a discontinued name for Fe rich Diopside. This was a Lechner collection piece (Austria) which was later sold by the Schortmanns's dealership. The Schortmann label dates this to the 1940's though the specimen is probably over 100 years old. The main crystal here is distinct, terminated and is a translucent oil-green color. Some scattered Chalcopyrite adds a contrasting gold. The Diopside is exposed partly but also is well-enclosed by the matrix which is mostly more Diopside. Simply never seen on the market this is a nicely crystallized bit of mineral history.
Zoisite var. Tanzanite - gem crystal
Merelani Hills, Lelatama Mountains, Simanjiro District
2.6 x 1.1 x .9 CM (thumbnail)
new year 2021
Fine thumbnail Tanzanite with the very best intense blue color. Excellent transparency best appreciated in person, this is an excellent grade and and in super condition. We selected this from a large parcel of the 2019 gem production looking for crystals that would be a shame to cut. This one is 25.6 Carats. This crystal has one clean contact on an edge and is broken only on the base where it was attached, the termination and faces are perfect. What may look like bruising in some photos is only internal reflections seen inside the glassy faces. Some nice thumbnail crystals can be found by hunting in a large mineral show but very few ever have this color saturation and quality.
