Vesuvianite- single Crystal
Jeffrey Mine, Asbestos
3.2 x 1.1 x 1.0 CM (miniature)
Pre Holiday 2017
The Vesuvianites that came out of the Jeffrey Mine are the most colorful and desirable in the world. This crystal has a two tone green color, gem clear areas and a sharp, perfect termination. Close examination shows what may be parallel growth or complex twinning. Overall a fine condition, undamaged prism with excellent color and bright luster. Found in 2002. Relatively affordable for this level of quality. Since the mine closed, these are fast becoming rare and very expensive when available.
A killer miniature of absolutely transparent bright gem Grossular from the Jeffrey mine. When the mine was running, there were many different habits, colors and associations of Garnet found, usually in small zones that were never repeated. Over the years many habits have become especially desirable to collectors and this habit is one of them. This has rich red-orange color with good crystal separation, brilliant luster and impeccable transparency. Overall the arrangement of the Grossular is esthetic and the whole displays well from all sides. No damage, an esthetic example for the specie from the worlds greatest Grossular locale.
A large, sharp, very pale green single crystal of Prehnite in blocky form. From the Jeffrey Mine, where some of the worlds best and largest Prehnite crystals were found. No damage and with good luster this is a nice thumbnail that shows the habit well. Prehnite is a rather common mineral but crystals over a half centimeter are very rare and only come from a few finds.
A crazy, complex specimen that is composed of several generation of well crystallized Vesuvianite in a riot of colors. From deep emerald green to magenta, yellow and more this single specimen seems to have most of the brightest color spectrum for Vesuvianite. The crystals are sized from druzy sprays to prisms of 3 CM and are in several habits, many are also bicolored. This is fully crystallized on all sides, overall in great condition, some contacts and minor chipping can be found on a few areas , but the best display faces are free of damage. Over the years it was working, the Jeffrey mine produced the worlds best and most colorful Vesuvianites in many habits and colors. This specimen provides many of the colors that collectors search for from here, presented in a sizable, complex piece that invites gazing. Far better in person too.
Big and fine, isolated Garnets to 1.5 CM (well above average for these) with excellent color and luster. In good condition overall, there is typical contacting on the backside and some chipping on one garnet but the largest main crystal is completely perfect. This could be trimmed to a competition grade thumbnail if desired but this small miniature size as is presents very well. A little addition of small Diopside crystals adds a nice touch. Classic form and with distinct separation of crystals that is so sought after from top grade Jeffrey Garnets. As the mine is now gone forever these have become almost impossible to get in good quality.
A nice classic Jeffrey mine Vesuvianite with fine color, good transparency and a very glassy luster. No damage seen by naked eye and even under 10X magnification. The main crystal is formed with a smaller prism alongside that is separately terminated.
Prehnite - sharply crystalized
Jeffrey Mine, Asbestos
2.9 x 1.8 x 1.7 CM (small miniature/ large thumbnail (toenail))
A textbook form presented in a cluster of sharp crystals. Well-crystallized prismatic Prehnite is quite rare and the best in the world are from old finds at the Jeffrey Mine. This specimen is perfect by naked eye with only very tiny contacts and chipping found with 10X magnification. A delicate pale green that looks almost white in some light, this is just a whisker too large to be a thumbnail but could be trimmed to fit if desired. No stains or encrustations, just lustrous bright Prehnite.
Vesuvianite - hot pink cap
Jeffrey Mine, Asbestos
2.1 x 1.6 x 1.1 CM (thumbnail)
An amazing color crystal from the golden years when the Jeffrey Mine was producing the world's best, and most colorful Vesuvianites. Electric purple-pink termination on a small but lustrous crystal. Contact and breakage on the back and underside but clean on the display side of the piece. This is one of the most rare and desirable colors. For anyone building a suite of Jeffrey Vesuvianites (in all imaginable colors) this intense piece is a must.
