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.
Pectolite is not usually an attractive mineral and good prismatic crystals are quite rare. This is a strong exception to that rule. More than 25 years ago a series of pockets at the Jeffrey Mine produced some of the most perfect and esthetic specimens of this usually drab mineral. Several crystals are transparent and all others are translucent. A perfect undamaged floater there is no matrix or point of attachment. Outstanding for the specie, choice, very large and rarely available now.
Small but intense rich purple Vesuvianite with magenta and dark green areas. The color is deeper and more intense than the computer monitor can render well. The luster is glass-like and the specimen clearly has two generations of growth. Some of the smaller crystals show hoppered terminations. The "matrix" is a blocky crystal of Vesuvianite that shows signs of being recrystallized as well. This is the most uncommon color found at Jeffrey and essentially unknown from any other locale.
Grossular with minor Natrolite
Jeffrey Mine, Asbestos
3.4 x 3.3 x 2.2 CM (small miniature/ large thumbnail (toenail))
A good specimen of a type that is becoming hard to find and often very expensive. This has a nice presentation overall but has damage to some smaller crystals and with magnification more chipping is seen, so it is not for perfectionists. Good value for color, luster and contrast with the light matrix. Shows good isolation of the Garnets too. Far less expensive than an ultra perfect specimen but in normal display looks just as nice.
