One of the most desirable and rare types of Grossular from the Jeffrey Mine are the frog-egg type. This specimen is a matrix of tiny Diopside crystals that hold several gem clear Garnets. Some of these are frog egg type with the colorless exterior and a bright green interior zone, much like frog eggs. The crystals are in excellent condition, very sharp and bright but small, with the largest just 2-3 MM in size. Despite the small size, the color is vivid enough to show the crystals to the naked eye. There is some fluorescence as well which is noted from some of the green Jeffrey Garnets. Very unusual to find a clean specimen in this price range now.

Fall 22
Glassy transparent pink color Garnets with emerald green cores on matrix. One of the great treasures found decades ago at the long gone Jeffrey Mine (Asbestos, Quebec) these are modern classics. Very hard to find now in any quality today on the market this piece has excellent luster and several clustered grossular crystals that are complete. Some edge damage exists but the important crystals are fine. Despite the "clustering" the individual crystals are still defined and very bright. For any suite of Garnets these are a must, this habit has never been found anyplace else on earth and there were not many found back then. "Frog-Egg" Garnets are usually very expensive, this piece offers very good value for cost.

Post Tucson 2022
Gem clear Garnets with glassy faces with vivid color and deep striations. The individual crystals are up to 1.3 CM across and contrast with the matrix. In excellent condition as seen, this is from the famed Jeffrey Mine, a modern classic locality that was at one time the source of the world's very best Grossular. Since the mine has been closed these have become much more prized, this miniature piece has a strong display impact that stands out.

New Year 22
From a relatively new find (2020-21) by Denis Beals; these are larger rose Garnets from an area of the Sierra de las Cruces. This site has produced a few relatively large Garnets embedded in a hard Rhyolite matrix. Noticeably different in habit and look from the previous finds in this region, this piece is an excellent example. A cluster of two main intergrown Grossular crystals show good luster and contrast well with the matrix. Some contacting is noted, there are geometric imprints of other Garnets and some rougher faces, as was true of every piece we examined from the find. Nevertheless, while this is not a piece for perfectionists it is still a fine and colorful Mexican Garnet unlike anything else from the region.

Early summer 2021
A plate of highly lustrous Garnets from the famed Ala Valley. The color and transparency of these Grossular is outstanding. There are several larger, more isolated crystals that are set in a matrix of much smaller Grossular. The larger crystals reach 1 CM and glow a vivid red when backlit. In normal lighting the color is darker red as seen in the photos. This is a particularly rich piece with a fine color and dense coverage of bright sparkling Garnet. Overall in very good condition, some rough spots are seen with magnification but these are very minor and almost invisible in the context of the piece. Far better than average esthetics and visual impact from the Piedmont region.

Thumbnail specimen of fine transparent Garnet. These are well-defined, isolated and brilliantly lustrous. The Garnets are perched on a very thin plate of matrix, all show glassy striations on the larger faces. From the great Jeffrey Mine, this thumbnail is a fine but scaled-down version of larger specimens that can cost a fortune when available.

Gem clear Grossular Garnets with the deep orange color that is most desired from this iconic locale. The Jeffrey mine Garnets were found in many different styles, habits and colors, they are regarded as among the greatest examples of the specie worldwide. This piece is in fine condition overall with glassy luster and less striations on faces than we usually see. The crystals are perfectly transparent, the matrix can be seen through them. Most of the crystals are clustered or touching each other on edges which is usually considered to be crowding but these do show good independent development and are not as jammed together as is often the case. A very pretty and affordable miniature gem Garnet specimen.

Jeffrey Mine, Asbestos (now Val-des-Sources, Estrie,

1.6 x 1.4 x 1.3 CM (thumbnail)
price: $450
new year 2021
Grossular from Jeffrey Mine that is transparent, has fine orange color and has several slender crystals of Diopside seen inside the Garnet. Aside from some very small contacts and rough edges this is in fine condition. The luster is glass-like and this crystal has very few striations on the large faces which makes it easy to see through these windows into the crystal. Ex Larry White thumbnail collection, he obtained this in the early 80's when the mine was still active and great things were being found.
