Andradite - large parallel position crystals
stock #20-FC-034-(9133)
Lac D Amiante, Black Lake Mine, LAB Mine, Chaudiere-Appalaches
Quebec, Canada
4.1 x 2.9 x 2.4 CM (miniature)
price: $900
Spring 2020

Flattened habit mint green crystals often called "Demantoid" are in a stacked alignment with almost no matrix present. From the now classic finds made over 25 years ago at Black Lake, these Garnets are far larger than the average and this is an incredibly enormous cluster, the largest we have ever seen. The biggest garnet in the cluster is over 2.2 CM across, it is huge for this locale where most are 2-3mm in size only. Translucent with some tiny areas of transparency, the luster is moderate, some faces are glassy but others are slightly dusted with and included by tiny needles of Pectolite with gives a more matte effect. In excellent condition at 20X magnification no damage or chips can be found which is also quite rare. For some reason many of the larger crystals we have seen had unusual or distorted habits including this sort of flattening. A very choice and huge green Andradite.

Prehnite - sharp gemmy crystals
stock #AX-24-495
Jeffrey Mine, Asbestos (now Val-des-Sources, Estrie,
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 (now Val-des-Sources, Estrie,
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 (now Val-des-Sources, Estrie,
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.

Serandite w. Aegirine etc
stock #20.1-067
Mont Saint-Hilaire, Monteregie
Quebec, Canada
5.7 x 4.3 x 3.4 CM (cabinet)
price: $975

Serandite crystals up to 3.2 CM with an unusually intense, rich color. This choice piece has a vivid rose pink that looks close to a Rhodochrosite red and contrasts well with the complex matrix. In excellent undamaged condition, the Serandites also have very bright luster. These are also fully translucent and transparent on thin edges. Serandite was never a common mineral and it turns out that many (perhaps most) Serandites in collections are in fact Schizolite and not Serandite. This is a real confirmed Serandite, with top color and form. Outstanding for the size and quality, The classic locality of Mt. St. Hillaire is THE place for this specie, no place else in the world ever had crystals of this size and quality.

Wardite -superb matrix crystals
stock #0769-JM-4030
Rapid Creek, Dawson Mining District
Yukon Territory, Canada
8.3 x 4.4 x 3.1 CM (cabinet)
price: $600
Spring 2020

From the noted John Marshall collection, this is an killer Wardite with fine, sharp and lustrous crystals perfectly arrayed in a distinct line. The Marshall collection card from 2003 states " Superb crystals on matrix, the display specimen in the British Museum is nowhere as good as this". Obtained from Gregory, Bottley and Lloyd, A great Wardite from anyplace the crystals reach 1.7 CM and are transparent in parts.

Manganoneptunite with Pectolite
stock #AX-16-519
Mont Saint-Hilaire, Monteregie
Quebec, Canada
6.8 x 3.3 x 2.8 CM (cabinet)
price: $100
Spring 2020

A complex open vug in crystalized Albite hosts bright red gem clear Manganoneptunites along with Pectolite needles and Siderite, Rhodochrosite etc. While the individual crystals are best appreciated with magnification, this ihas color enough to be a display specimen, a good addition to any St Hillare suite. Often Manganoneptunites are dark, almost black or are crude crystals, but these are bright and perfectly formed.

Silver - wires with Quartz
stock #AC-379
Cobalt, Gowganda region, Timiskaming District
Ontario, Canada
6.9 x 5.9 x 4.3 CM (cabinet)
price: $760
Spring 2020

Silver wires with tiny Quartz crystals coating and encasing some of the Silver. From the prolific Cobalt area this specimen is fairly old, it was sold by the Schortmann Brothers in the early 1960 era. The Quartz undermagnification is a sparkling druze of doubly terminated crystals many of which have a Cumberland habit. Close exam of the matrix shows that there is a lot more silver unclosed under layers of Quartz. The exposed area of wires is a dense nest with a few slender hairs rising to about 3 CM long. A choice, delicate and esthetic piece which looks better the more it is examined.
