2.2 x 2.2 x 1.3 cm. From the famous Mexican discovery, these famous red garnets have graced many important collections. This superb dodecahedron, .7 cm across and having excellent luster, sits perfectly atop the quartz matrix. Ex. Wendell E. Wilson Collection.
5.6 x 3.8 x 3.4 cm. These specimens came out about 6 years ago. The piece features unusual modified honey-golden colored crystals of Grossular associated with rich green (possible Chromium-bearing), gemmy prisms of Diopside on limestone matrix. Ex. Richard Kosnar Collection.
5.7 x 5.2 x 4.0 cm. Gemmy and lustrous, orange-red, garnets to 9 mm are aesthetically scattered on a 3-dimensional matrix of olive-green diopside crystals on this CLASSIC and VERY FINE piece from the famous Eden Mills Mine of Vermont. Henry Minot specimen.
1.0 x 0.5 x 0.3 cm. A 2.38-carat pure gem crystal of one of the rarest and most prized gemstones of all - bright green tsavorite garnet.
1.4 x 1.1 x 0.9 cm. This is a large, nearly-gem quality tsavorite garnet on matrix! It measures one centimeter from side-to-side and top-to-bottom, and is about half a centimeter in thickness. The weight is estimated at around 6 carats! These have become nearly impossible to get in matrix - they are so much rarer than diamonds, or even rubies, that there is no comparison. The faces of this crystal are sharp and glassy. The transparency and brightness are just amazing!
2.4 x 1.3 x 1.1 cm. A cluster of gemmy hessonite garnets, to 1.2 cm, from this now-closed mine.
0.9 x 0.6 x 0.6 cm. A BEAUTIFUL, gemmy and intensely emerald-green, 2.45 carat tsavorite garnet crystal from the Merelani Hills of Tanzania. This pristine, glassy crystal is a complexly crystallized floater with many faces.
7.3 x 5.7 x 5.2 cm. A showy, old-time and excellent combination specimen from the famous Thetford Mines of Quebec of bright green, chrome, grossular garnets aesthetically nested on a jackstraw matrix of lustrous, translucent to opaque, tan to green, diopside prisms. An excellent, old piece from the George Elling Collection.
6.9 x 5.4 x 4.9 cm. This salmon-pink garnet is just hard to believe for its size and the textbook perfection of its form. It is fist-sized! It is complete except for one corner, where there was probably a contact. The crystal has very good luster as well. You do not normally see such large xls in this condition. Ex. Gene Meieran Collection.
5.8 x 4.9 x 3.7 cm. This grossular crystal is olive-brown, with high luster. You can see some euhedral contacts where little grossularites grew against it. Ex. Gene Meieran Collection.
4.7 x 3.5 x 2.5 cm. A BEAUTIFUL, gemmy and lustrous, 1.0 cm, sherry-red, hessonite garnet crystal jauntily perched on matrix with smaller garnets from an uncommon, but well-known Washington locality - Vesper Peak. Choice material from the George Elling Collection.
6.5 x 4.8 x 4.7 cm. VERY gemmy and lustrous, reddish brown grossular garnet crystals to 8 mm with distinctive, frosted edges RICHLY cover three sides of VERY UNUSUAL matrix - a large, crude pseudomoph of a big fat epidote crystal. This showy and historical piece is from Eden Mills, Vermont. There are actually very few damaged garnet crystals on this fine specimen and the bit of contacting and the broken ends of the pseudo are certainly not detracting. Henry Minot specimen.
3.4 x 3.1 x 1.4 cm. These Jeffrey Mine garnets have always been sought after, but much more so since the mine closed a couple of years back. Now they are quickly grabbed up whenever they become available. This specimen has super-gemmy and bright crystals to 0.7 cm, and it is distinguished by having nice 3-dimensionality, rather than being the usual flat plate with the crystals pressed together.
8.2 x 6.5 x 6.5 cm. A generous grouping of gemmy and lustrous wine-red Grossulars up to .8 cm, on Clinoclore. These Garnets are so good that this classic Italian locality has long been considered a European classic. Ex. Martin Lewadny Collection.
4.9 x 2.9 x 2.9 cm. Pink garnets are not uncommon from Lake Jaco, but when they get this RED, with some actual translucency to them, they are really rare. This 1.2-cm crystal is dramatically isolated on matrix. It has one clean, natural contact face on one side where it grew against matrix or another crystal.
