We see very few Bournonites from Trepka and almost never of good esthetics. This is a very pretty specimen with the best quality we have ever seen. The most prominent Bournonite crystal is perfect, undamaged 1.4 CM in diameter and has bright metallic luster. It is a textbook quality twin with cogswheel form on the edges. The whole piece has choice contrast with brilliant Pyrite forming most of the matrix. Trepka has been known as an excellent source of other Sulphides. This new find was small but had impressive Bournonites which is certainly newsworthy and exciting.
Grossular -rare colorless crystals
Jeffrey Mine, Asbestos
3.3 x 3 x 2.2 CM (small miniature/ large thumbnail (toenail))
Garnets that are colorless are surprisingly rare world wide, only a few small finds have ever been made. Grossular that is colorless and gem clear is even more rare, and a choice matrix specimen packed with crystals is exceptional. The largest crystal on this piece is 1.1 CM in diameter, quite huge for the specie. From the great Jeffrey mine, this is a choice very glassy piece in fine condition. For any serious Garnet collection, this is hard to capture in photos but is great in person.
Rutile on Hematite
3.6 x 3.4 x .2 CM (miniature)
Epitaxial arrangement of Rutile needles in the six ray form that is famous from this locality in Bahia, Brazil. A choice small example of metallic silver-black Hematite crystals with typical very flat habit hosting radiating needles of Rutile. Close exam of the Hematite faces shows complex striations and some embedded Rutile.
Rapid Creek, Dawson Mining District
4.6 x 3.2 x2.3 CM (miniature)
Superb, larger sized Augelite crystals of top quality in an esthetic cluster. Killer condition (no damage) and with the largest crystal 1.6 CM. Augelite is a rather rare Phosphate only found in such fine crystals like this from two localities worldwide. This specimen is exceptional for the Rapid Creek finds and has fine zoning, sharp, lustrous faces, nice color and some gemmy areas. This remote area of the Yukon has been a world class source of fine Phosphate specimens. The Augelites from here are distinctly different from the the newer finds at Mundo Nuevo (Peru).
Grossular -Gemmy crystals
Jeffrey Mine, Asbestos
3.1 x 2.1 1.3 CM (small miniature/ large thumbnail (toenail))
A cluster or stack of very lustrous Garnets with the classic color and form that made the Jeffrey Mine world famous. This is the flattened type of cluster with no matrix, it is entirely contacted on the back as was the case with this style, fully translucent and mostly transparent. This type of specimen was sometimes used as a sort of natural jewelry, mounted or wire wrapped as is or with the back ground flat. A very good value these Garnets show characteristic striations and growth hillocks. A fine modern classic from a source that will never again produce anything.
Mina Ojuela, Mapimi
5.7 x 4.6 x 1.9 CM (cabinet)
Adamite crystals standing up from the limonite matrix in both white and light mint green colors. Early seventies vintage specimen from Mina Ojuela, ex Les Hitchings collection. Vivid fluorescence and in excellent condition. A few Calcite crystals are also on the matrix but this is mostly all Adamite. So much good Adamite came out during that period in many habits that these were under respected. Currently much less is coming out and we know this was a golden age for the worlds best examples of this specie. Choice display with good visual impact for the size.
Heights Mine, Durham, Weardale County
4.1 x 3.3 x 3.3 CM (miniature)
Perfect and well composed Fluorite from the Heights mine. This cute miniature has a prominent, well isolated and very sharp cube perched on top. The edges and corners are sharp and perfect on this, the luster is glasslike and the Fluorites are quite transparent. No visible damage. A good value for a small, choice classic British Fluorite with a quality well beyond typical.
Quartz on Chrysocolla and Malachite
Phelps Dodge Morenci Mine, Morenci, Copper Mt. Mining District, Greenlee
11.6 x 8.1 x 6.2 CM (cabinet)
A large colorful Copper secondary display specimen from an old find in Arizona. A druze of tiny clear Quartz crystals is covering many green Malachite balls and areas of bright blue Chrysocolla. The overall effect is sparkling and vivid in person. A sizable specimen from Morenci. The bulk of the matrix is layers of Chrysocolla in several shades of blue looking like a rich Turquoise. Some of those thin layers seem to be "gem Silica" that when thick enough is highly sought after for Lapidary. These layers are too thin for that and the surrounding Chrysocolla is quite brittle besides. The matrix has been properly stabilized to keep it from cracking as some Chrysocolla can do. This piece is early sixties vintage and simply eyecatching.
