Grossular - gem clear, with Diopside inclusions
stock #20.1-307-(LW461)
Jeffrey Mine, Asbestos
Quebec, Canada
1.6 x 1.4 x 1.3 CM (thumbnail)
price: $450


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.
Vesuvianite -
stock #18-AX-22-088
Jeffrey Mine, Asbestos
Quebec, Canada
3 x 1.7 x 1.4 CM (small miniature/ large thumbnail (toenail))
price: $360


A vividly colored, complete, doubly terminated crystal (a "floater") with no matrix. From the Jeffrey Mine which is the only locality that ever produced such colorful Vesuvianite. Highly lustrous in person the crystal has is mostly a mix of green hues from dark to lighter yellowish and has one spot of purple. In fine condition, the faces on this are multi stepped and quite a bit more complex than most crystals from this famed locale. The mine has been closed for years but the heritage of its minerals is world renowned. Choice
Grossular -rare colorless crystals
stock #18AX-24-467
Jeffrey Mine, Asbestos
Quebec, Canada
3.3 x 3 x 2.2 CM (small miniature/ large thumbnail (toenail))
price: $680
Spring 2020

Garnets that are colorless are surprisingly rare world wide, only a few small finds have ever been made. Grossular that is colorless and gem clear is even more rare, and a choice matrix specimen packed with crystals is exceptional. The largest crystal on this piece is 1.1 CM in diameter, quite huge for the specie. From the great Jeffrey mine, this is a choice very glassy piece in fine condition. For any serious Garnet collection, this is hard to capture in photos but is great in person.
Grossular -Gemmy crystals
stock #18.1-763
Jeffrey Mine, Asbestos
Quebec, Canada
3.1 x 2.1 1.3 CM (small miniature/ large thumbnail (toenail))
price: $280
Spring 2020

A cluster or stack of very lustrous Garnets with the classic color and form that made the Jeffrey Mine world famous. This is the flattened type of cluster with no matrix, it is entirely contacted on the back as was the case with this style, fully translucent and mostly transparent. This type of specimen was sometimes used as a sort of natural jewelry, mounted or wire wrapped as is or with the back ground flat. A very good value these Garnets show characteristic striations and growth hillocks. A fine modern classic from a source that will never again produce anything.
Prehnite - sharp gemmy crystals
stock #AX-24-495
Jeffrey Mine, Asbestos
Quebec, Canada
3.4 x 2.7 x 2 CM (small miniature/ large thumbnail (toenail))
price: $780
Spring 2020

Prehnite crystals which are unusually sharp, clear and distinct with textbook perfect form. An older specimen from the Jeffrey Quarry in Quebec which was at one time an incredible source of fine and often unique Prehnites. This is in flawless condition damage-wise. The matrix is a mix of needle crystals of Pectolite and micro Natrolite. The matrix is fluorescent as well. Very much a three dimensional specimen that displays well from almost any angle, the overall esthetics are impressive.
colorless Grossular on Prehnite
stock #AX-24-475
Jeffrey Mine, Asbestos
Quebec, Canada
3.7 x 2.4 x 2.1 CM (small miniature/ large thumbnail (toenail))
price: $440
Spring 2020

Doubly terminated Prehnite (3.7 CM) crystal showing sharply striated, glassy faces encrusted with small colorless Grossular crystals. One of the rarest colors for Garnet are the clear or white crystals which were found more than 30 years ago at the Jeffrey Quarry. Just as uncommon is the vivid fluorescence (orange to red) of these Grossular. The underlying Prehnite shows through on several areas of the specimen and is highly lustrous with distinct stepped structures and striations. No damage, a rare and choice combination from a classic, extinct locale. I understand this combination (Prehnite with colorless, fluorescent Grossular) is unique in this one find, and never seen elsewhere on the planet.
Prehnite -well crystallized with Pectolite
stock #AX-16-543
Jeffrey Mine, Asbestos
Quebec, Canada
4.7 x 3.3 x 3.2 CM (miniature)
price: $500
Spring 2020

Some of the best Prehnite ever found came from the Jeffrey Quarry and it came in many different habits and colors. The orange color on this piece is quite rare and the well isolated crystals reach to just under 2 CM. The crystals also show the curved and twisted faces that give a rounded, globular look at first glance. The matrix also hosts many needle crystals of Pectolite that add some sparkle on close inspection. Damage free, this is a well composed piece with the largest crystals prominently positioned. A choice Prehnite from anyplace and an especially fine, rare type from the Jeffrey Quarry.
Grossular - fine Gem Garnet
stock #AX-31-006B
Jeffrey Mine, Asbestos
Quebec, Canada
1.7 x 1.7 x 1.5 CM (thumbnail)
price: $950


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.
