7.4 x 6.9 x 5.2 cm. A very unusual Mexican combo specimen that combines sharp, brassy octahedrons of pyrite with translucent crystals of grossularite and books of platy hematite. This is an old-timer.
14.7 x 11.7 x 6.4 cm. This is a large plate with dozens of crystals, to 1.5 cm, and a lot of color spread out on that stark white matrix. These garnets are called raspberry garnets by many people for their unique color and sharp form.
Lustrous, gemmy grossulars to half a centimeter cover the top half of this specimen, with grayish diopside crystals providing a contrast at the bottom. 5.5 x 5.5 x 1.8 cm
3.3 x 2.5 x 2.1 cm. Gorgeous, water-clear, super gemmy, cinnamon-colored hessonite grossular garnet crystals to 1.7 cm grew around and are wrapped over a thin slab of matrix on this fine two-sided specimen from the famous Jeffrey Mine of Quebec. The crystals are amazingly limpid, you can easily see the white matrix beneath these gems. 3 of the 4 crystals are visible on both sides. Ex. Dr. Gary Hansen dealer stock and not seen since the early 1980s.
11.9 x 5.6 x 2.8 cm. Gemmy, brilliantly lustrous garnets to 1.1 cm make this large matrix plate a showy piece, and with high quality crystals. This large plate has many crystals, and all are transparent and have the classic orange color.
SUPERB gem grossulars to 6or 7mm cover the face of this specimen, showing wonderful striations, excellent orangey color, just glassy luster. Some edge damage at the lower edge and periphery, but not to the display core. Showy piece, and this location is now closed, so it only gets rarer with time from here on out. 6.2 x 3.5 x 3.2
SUPERB gem grossulars to over one centimeter cover the face of this specimen, showing wonderful striations, top sherry color, just everything you would want in a Jeffrey grossular. Great piece, and this locaiton is now closed, so it is like money in the bank. 8 x 6 x 1.8 cm
6.7 x 4.2 x 2.5 cm. An unusual locality piece…a plate of Erongo garnets. Large (up to 1.7 cm) purple-red Grossular Garnets embedded in Calcite. Additionally, the garnets have a complex, and very attractive, striation pattern very similar to those that have come out of China in the last decade, along with good luster. Ex. Charlie Key.
2.4 x 2.3 x 1.2 cm. This is a fine, large grossular specimen with big, gemmy crystals to one cm. You can see the flat, absolutely glassy faces accented by pretty, striated ones, all over this piece.
Lustrous, DEEP green crystals of the deepest color possible for the species and location due to chromium content, this is a fantastic display piece of a rare varietal of Grossular not found in many years. I am further told by a collector who has been there often that the cr-grossular from Thetford Mines are usually not bigger than 3 cm x 2cm, with less than 2 mm crystals. These crystals reach 5 mm in size and this piece is covered with them, complete and undamaged save around the periphery. 5 x 4.5 x 4 cm
4.6 x 2.7 x 2.3 cm. A superb and classic combination miniature from a historic Italian locality - Testa Ciarva, Piedmont. This very aesthetic piece is studded with gemmy and lustrous, red to orange grossular garnets and is beautifully highlighted by the single, 5 mm grossular on the central, column-like spray of glassy, pastel-green diopside crystals.
The best garnet specimen available at Costa Mesa from the Fersman Museum folks, who brought out this new find. Dmitriy Belakovskii said that few larger pieces were available and of the ones I saw, this was the only aesthetic specimen for my tastes. It features pristine, large, very lustrous crystals to 1.5 cm along the upper 2/3 of the specimen. The bottom part is more massive and could certainly be trimmed to improve the overall look of the piece. Quite impressive in person, especially for a Russian grossular/hessonite! 8.6 x 8.0 x 5.0 cm
7.4 x 3.8 x 2.6 cm. Beautifully gemmy and lustrous, cherry-red hessonite (grossular) garnets with complimentary, tabular, green clinochlore crystals form an outstanding and impressive specimen from a famous Italian locality - Bellecombe in the Aosta Valley. Super rich material from this classic locale.
6.8 x 6.3 x 2.8 cm. From the personal garnet suite of Bill Larson, a superb specimen of grossular from Eastern Europe. The crystals, to 1.3 cm, are super-sharp, and have fine luster, and a pretty mossy-green color. This is rare material from a little-known locality.
8.3 x 6.0 x 4.2 cm. A superb specimen of sharp, lustrous, diverging, bulb-like quartz crystals included with gray-green hedenbergite. The dominant, central quartz crystal is 5.5 cm tall. The quartz crystals rest on a matrix that is essentially solid grossular garnet microcrystals. This superb specimen, for the combination species, was collected near the Blue River, 180 km from Dal’negorsk, Russia in 2001.
