Grossular (Var: Hessonite), Diopside from Belvidere Mountain Quarries (Vermont Asbestos Group mine; VAG mine; Ruberoid Asbestos mine; Eden Mills quarries), Lowell & Eden, Orleans & Lamoille Cos., Vermont, USA [db_pics/mdpics/MD-258969a.jpg]

2 x 1.8 x 1.8 cm. Superb pair of intergrown Garnets sitting on a bed of diopside crystals. Eden Mills garnets rate high in the pantheon of garnets, and this specimen is a superb specimen. Both crystals are virtually perfect. Deep amber in color and gemmy, together they measure a full 1 cm across. This thumbnail has amazing aesthetics and the crystals are gemmy…a superb old classic. Ex. Wendell E. Wilson Collection.

Grossular from Jeffrey mine (Jeffrey quarry; Johns-Manville mine), Asbestos, Les Sources RCM, Estrie, Québec, Canada [db_pics/mdpics/MD-258971a.jpg]

2.2 x 2 x 1.2 cm. The Jeffrey Mine has produced perhaps the finest garnets in the world, and this fine thumbnail is no exception. The crystals, which have unusually good separation and definition, are lustrous with a deep amber color. The largest crystal is 1 cm across. Ex. Wendell E. Wilson Collection.

Grossular from Konar Valley (Kunar Valley), Konar (Kunar; Konarh; Konarha; Nuristan) Province, Afghanistan [db_pics/mdpics/MD-261508b.jpg]

11 x 6.5 x 4 cm. Glassy and translucent, brownish-orange grossular garnet crystals, to 2.5 cm across are emplaced on a garnet rich matrix (with much damage between the otherwise nice crystals). Although some of the crystals are damaged, the color, luster and size of the remaining crystals make this specimen a fascinating piece.

Grossular (Var: Chromian Grossular), Diopside from Jeffrey mine (Jeffrey quarry; Johns-Manville mine), Asbestos, Les Sources RCM, Estrie, Québec, Canada [db_pics/mdpics/MD-261619b.jpg]

10.2 x 5.2 x 2.8 cm. These crystals, despite their size, are still some of the darkest, richest green Chromium-bearing Grossular crystals I've seen from any locality. There are literally dozens upon dozens of very small, bright, lustrous, dodecahedral neon green Chrome Grossulars with tan-colored, bladed Diopside crystals on matrix. A very attractive piece from this classic, and now defunct world locality.

Grossular from Jeffrey mine (Jeffrey quarry; Johns-Manville mine), Asbestos, Les Sources RCM, Estrie, Québec, Canada [db_pics/mdpics/MD-26320a.jpg]

Jeffrey Mine garnets of any quality are disappearing rapidly, and this specimen consists of two HUGE crystals stacked on top of one another! They have wonderful luster, incredibly cool diamond-shaped striations on their faces, and are extremely gemmy! Each crystal measures just about 2.5 cm and the piece is complete extcept for the natural contact on the bottom. The back of the specimen is flat, a natural contact face. THIS IS HUGE FOR THE LOCALITY! The specimen was repaired, to reattach the two crystals at their natural junction, but the fit is exact and clean and not noticeable. THIS QUARRY IS NOW closed and gone for good. this piece has enormous display impact. Old material from the Gary Hansen Collection (reflective of 1970s-80s dealer stock) 4.1 x 2.7 x 1.5 cm

A SUPERB and AESTHETIC miniature cluster of VERY GEMMY orange grossular garnet crystals to 1.4 cm from the now-closed Jeffrey Mine, Quebec, Canada. Some of the smaller crystals are preferentially frosted. 3.9 x 2.6 x 1.3 cm

4.5 x 2.9 x 2.1 cm. Grossular from Eden Mills is the standard to which other US localities must be compared. They have a richer, redder red color saturation than material from Canada, and are quite distinct. Vesper Peak garnets have too dark a color in comparison - these are "just right" and not too dark, not too light. The brilliance and sharpness of these garnets is such that the piece looks carved...you can see, the photograph makes them look a little bit airbrushed, but this is not the case. They really are that sharp and symmetric. This specimen is unusual in the consistent color quality across the whole piece, the size of the crystals (to 1.8 cm), and in the fact that it is nearly a complete floater with no damage and only a small point of attachment on the lower backside. Tiny druses of quartz accent the 3-dimensionality of this piece, as well. It is, overall, a full-sized miniature. This specimen was collected by Ken Hollman in 1969. For those who did not know him, Ken assembled one of the largest and most important collections of classic Eastern US material, and had excellent taste. He also was a consummate field collector and a particular expert on this locality. This was his favorite garnet specimen, out of the many he collected in his lifetime, as related to me by his friend Phil Scalisi (who owned the specimen until recently). Scalisi's label accompanies the specimen and relates that Hollman considered this "his very favorite Eden Mills piece. I exchanged it from Ken for several of my best Chessy Azurites."...and those were valuable pieces, I can say, having seen Hollman's extensive and important Chessy suite at one time. The specimen remained in Scalisi's collection for several decades, until its recent sale. Photo by Joe Budd.

4.8 x 4.2 x 3.4 cm. Supremely gemmy and lustrous, cinnamon-orange grossular garnets are aesthetically set on sculptural matrix covered with very glassy, pastel-green to colorless diopside needles on this fine combination specimen from the Jeffrey Mine. The isolated single crystal is 8 mm and the cluster is 1.5 cm across. Classic material from the Wes Parker Collection.

Grossular from Sierra de la Cruz, Mun. de Sierra Mojada, Coahuila, Mexico [db_pics/mdpics/MD-27281a.jpg]

A SUPERB grossular specimen, with unusually sharp, translucent crystals of perfect form and flashy lustrous faces. This specimen came out of the George White collection. It is unusual in that it is a complete-all-around cluster while most ar eloose singles from here. 3.7 x 3.6 x 3.2 cm

5 x 4.3 x 2.4 cm. A superb plate of two generations of cherry-red Grossular Garnets. The first generation averages about .3 cm in size, and they are lustrous, translucent to gemmy, and glow beautifully under good light. The second generation of larger crystals range up to 1.1 cm, have very good luster, and are translucent. Definitely one of the best and most attractive of these particular specimens that I have seen, and they are quite rare in large crystals from this mine. Ex. Charlie Key.

Grossular from Thetford Mines, Les Appalaches RCM, Chaudière-Appalaches, Québec, Canada [db_pics/mdpics/MD-27454a.jpg]

Extremely dark green, chromium-colored garnets from a rare find at this now-closed locality! Though the crystals are smallish by standards of other locales, to 3 mm or so, this is typical of the material and in fact this is LARGER than most such crystals. What is atypical for the specimen is the sheer richness of the deep green hue, which is in the top percentiles of color quality. I nperson, these have a much more brilliant lustre, as well! 5 x 4 x 1 cm

7.0 x 4.8 x 2.0 cm. Beautiful, brilliant, gemmy, dark cherry-red hessonite crystals to 6 mm are richly scattered on the matrix plate covered with books of silvery-green, partially gemmy clinochlore lamellae on this fine specimen from a classic Italian locale - Carboneri in the Pellice Valley. This is very highly representative and rich combination material from this noted locale. Ex. Wes Parker Collection.

7.2 x 6.3 x 1.9 cm. A glistening, jewel-like plate of just solid gemmy garnets. The locality is now officially defunct and only a handful of specimens still come out as obtained by the occasional person who can get down in the mine in a roundabout fashion. This is a large, fine specimen. When backlit it is translucent.

1.6 x 0.9 x 0.7 cm. A nice combination thumbnail from Eden Mills and the Robert Whitmore Collection. A beautiful, gemmy, reddish-orange grossular garnet is aesthetically perched on lustrous, parallel-growth diopside blades. The garnet is a textbook dodecahedron and has striking points of orange fire. Classic combination material from this very well-known locale.
