Grossular green-core "frog egg"
stock #18 -AX-392
Jeffrey Mine, Asbestos
Quebec, Canada
1.7 x 1.6 x 1.4 CM (thumbnail)
price: $290


A small thumbnail showing intense green core clear Grossular crystals. This habit was often called "frog egg" and was only found at the Jeffrey Mine, and only rarely. Ex Larry White collection, he obtained this in 1975, at that time it was labeled as a Uvarovite, a common error when these were first found. This specimen has super sharp, gemmy crystals with a small bit of matrix. The luster is bright glassy, transparent and is over all in fine condition. Looks especially great under magnification where small details can pop out. These have become very hard to get and it seems there will never be more. Small but very eye catching.
Prehnite -elongated crystals
stock #18.1-393
Jeffrey Mine, Asbestos
Quebec, Canada
3.9 x 3 x 1.8 CM (small miniature/ large thumbnail (toenail))
price: $130
Late Summer 2018

The amazing Prehnite crystals from Jeffrey mine took many forms and habits, unlike anything ever seen elsewhere. Although Prehnite is not really a scarce mineral, sizable prismatic Prehnite crystals are incredibly rare. This prismatic Prehnite cluster is a good example, sharp, with some complete doubly terminated crystals to 3.8 CM long. The luster is pearly and the crystal tips are transparent, the body is more milky translucent. There is chipping only on the outer edges, the center area is pristine and undamaged. A good small miniature showing an elongated habit, wide center sections and with square cross section terminations.
Vesuvianite
stock #18-AX-23-143
Jeffrey Mine, Asbestos
Quebec, Canada
8.8 x 7.2 x 6.1 (cabinet)
price: $720
Late Summer 2018

Large block of nearly pure Vesuvianite with every side showing bright crystals to 1.6 CM though most are much smaller. Some contacts and very small chipping can be found so the pricing reflects this, yet the overall display impact is strong. An excellent value for a showy Jeffrey Vesuvianite. A few additional vugs hold the rare Emerald green (so called Chromian) Vesuvianite and a few bits of purple color pop out too. Overall this is the classic mint green color, sparkling with glassy luster on crystals that are transparent to translucent.
Serandite (on Albite)
stock #18-AX-27-094
Mont Saint-Hilaire, Monteregie
Quebec, Canada
2.2 x 1.8 x 1.2 CM (thumbnail)
price: $190
Late Summer 2018

A very cute thumbnail of bright, transparent Serandites on contrasting Albite. Serandite is usually opaque or at best milky, translucent on thin edges. These tiny crystals are transparent, colorful and lustrous. As is typical of St Hilaire specimens there are micros of other species as well, most noticeably Polylithonite and Natrolite. Despite the small size the luster and color make this one pop.
Diopside with Grossular
stock #18.1-389
Jeffrey Mine, Asbestos
Quebec, Canada
2.6 x 2.2 x 1.8 CM (thumbnail)
price: $70
Late Summer 2018

Mostly a Diopside thumbnail but with some bright orange Grossular tucked between the crystals. A waxy yellow-green color that is not very common at the Jeffrey mine. The central area of the piece is undamaged and well formed, only the outer edge has some chipping. A very affordable but well crystalized piece.
Pectolite
stock #18.1-390
Jeffrey Mine, Asbestos
Quebec, Canada
2.4 x 1 x .7 CM (thumbnail)
price: $220
Late Summer 2018

Probably the worlds best and largest Pectolite crystals came from the Jeffrey mine years ago. These were often slender, flat blades or needles often in spectacular sprays and groups. Sharp euhedral prisms like these were much more rare. This one is just large, doubly terminated crystals that have crisp sharp edges, glassy faces, is translucent to transparent. Perfect, undamaged glassy prisms in a nice arrangement, no place else on the planet has ever formed Pectolites like this. These have the characteristic one sided chisel termination and a hint of green. A choice thumbnail of a mineral not often considered for fine crystals.
Siderite (huge Crystal) with Albite
stock #18.1-361
Mont Saint-Hilaire, Monteregie
Quebec, Canada
10.6 x 9.7 x 5.8 CM (cabinet)
price: $4800
Late Summer 2018

A monster! The main crystal is as large as these have ever been found, and one of the best. The big crystal measured on the edge is 7.5 CM and on the diagonal is 9.8 CM across. Very impressive, this piece is one of the top three of the giant St Hillaire Siderites, and outstanding for the specie world wide. Sharp and fairly lustrous as well, the honey brown color has yellow highlights and is translucent. The matrix is the sort of elongated Albite crystals that look a lot like Natrolite. Ex Hitchings collection, obtained in 1967 the early part of the "golden years" at St Hillaire. In fine condition there is a contact on the backside but no damage. Even the smaller crystals in the cluster here would be choice specimens alone but they add a nice esthetic touch to the whole piece.
Serandite with Natrolite and Elpidite
stock #AX7-256(337A)
Mont Saint-Hilaire, Monteregie
Quebec, Canada
4.8 x 2.8 x 1.9 CM (miniature)
price: $650
Worldwide mix summer

Cluster of sharp intergrown Serandite crystals with the flat blade habit that host several terminated Natrolite prisms and one Natrolite rosette. The Serandites also have a few needles of Elpidite as well, and all are in remarkable, intact condition. Ex Larry White collection, this includes his homemade Balsawood base. Fine delicate prisms and vibrant pink color, this is an uncommon form for Serandite and this piece is especially esthetic.
