Henderson Mine, Chibougamou
3 x 2.3 x 1.8 CM (small miniature/ large thumbnail (toenail))
An esthetic cluster of shining Cubanite crystals all showing classic twinningset on just a sliver of matrix. The Henderson Mine at Chibougamou has been closed for many years, it was the only source of these fine, sizable Cubanite crystals. The largest crystal in this cluster is is 2 CM across, and sits well on top of the specimen. Close exam shows some minor bruising, contacts and natural cracks, so this is not for perfectionists, but as Cubanite is a very delicate mineral this is in relatively fine condition. and far better than average. Some areas that look like damage in the photos are on inspection fully intact and crystalized with a rough texture. The metallic luster is excellent and has a nice patina. These are a modern classic and somthing of a "holy grail" for most collectors, the starburst twinning habit is especially desirable. An excellent value for the quality.
Bright, lustrous, colorful and incredibly well formed gem Garnet from the Jeffrey Mine. A tiny bit of Diopside matrix and a small side car crystal are the only additions. In fine condition as seen, a quite superb thumbnail with well defined striations and a glass-like look. Single complete and well isolated crystals of this size are especially desirable. There were never many of top quality Grossular when the quarry was working but now these are just never seen.
Unusually large, sharp lustrous and very well defined Cubanite. Although Cubanite has been found at several locales in the world, the only source of fine crystals was the Henderson Mine, now long closed. There will never be any more of these which are by far the worlds best Cubanites. This specimen has a super dispaly face with very sharp striations and clear twinning. Some contacting on the back but the front displays very well. Specimens of this quality can only be had from old collections being recycled, and this size is almost never seen.
Diopside -single crystal
Orford Nickel Mine, Brompton Lake, Sherbrooke
5 x 1.6 x .8 CM (miniature)
Exceptional, perfect, partly gemmy and with glassy luster this is a great Orford Diopside. There were larger crystals found years ago but few were so well defined. This has the desirable honey yellow color and looks better in person. A modern classic with top quality, perfectly undamaged and looks fine from every angle.
Vesuvianite -Gem clear
Jeffrey Mine, Asbestos
2.2 x 1.6 x .8 CM (thumbnail)
Thumbnail of Gem Vesuvianite that has an unusual side crystal. On this a slender off shoot crystal juts out at an angle. It is not so unusual to see very tiny crystals encrusting the sides of Vesuvianites but this sort of prismatic crystal is very rare. in fine condition as seen, no damage or chipping, a clean prismatic contact is on the back side of the main crystal. The Jeffrey mine at one time produced many good Vesuvianites, but very fine pieces were always rare, and now there are no more of any quality.
Vesuvianite -2 generations
Jeffrey Mine, Asbestos
3.1 x 2.6 x 1.5 CM (small miniature/ large thumbnail (toenail))
A killer for the size, this is a perfect 360 degree undamaged specimen of bright and colorful Vesuvianite. The main crystal is an intergrown cluster of striated green prisms that are all sharing the same termination. This is perched on some smaller green crystals which are partly coated with smaller light purple-violet Vesuvianites. These are also very lustrous and have lots of sparkle. Vesuvianites from the Jeffrey Mine are by far the most colorful and attractive of the specie. They are also wonderfully diverse and this one is quite unusual as well as a fine display piece.
Small but very impressive thumbnail of intense green Garnets sitting on a druze of tiny Diopside crystals. The Diopside is slightly greenish in color and is fluorescent a bright yellow while the Grossular (in 450 NM light) is a brilliant red. Even without this very rare response for a garnet, the specimen is super attractive, the Garnets are gem clear, lustrous, sharp and undamaged. From the great Jeffrey mine, this is a tiny treasure.
Unusually sharp and transparent crystals of Prehnite in an esthetic cluster. The crystals are in fine undamaged condition and this specimen has a lot of display impact. The Jeffrey mine is famed for its Garnets and Vesuvianite but the Prehnites found here were world class and of incredible variety. This is an excellent example showing the elongated blocky form with a delicate light green hue. Even though Prehnite is not a rare mineral and is found worldwide, good sharp crystals are rare and these from the Jeffrey are unique. Not found for some years, these are modern classics and no others from elsewhere have this look and habit.
