Grossular - frog-egg type
stock #17.1-462
Jeffrey Mine, Asbestos (now Val-des-Sources, Estrie,
Quebec, Canada
4 x 3.5 x 2.2 CM (miniature)
price: $380
Spring 23

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.

Fluorite on Quartz
stock #22.1-548
Aouli. Midelt, Khenifra Province
Draa-Tafilalet Region, Morocco
4.8 x 3.1 x 3 CM (miniature)
price: $160
Spring 23

Bright yellow Fluorites on contrasting reddish druzy Quartz. The main Fluorite is elongated and gem clear; a very glassy contrast to the matrix. Close exam shows many odd inclusions in the crystals, but overall this a simply a cute, colorful and affordable Fluorite.

Vesuvianite - classic multi-color crystals
stock #14.1-046
Jeffrey Mine, Asbestos (now Val-des-Sources, Estrie,
Quebec, Canada
4.1 x 2.3 x 1.5 CM (miniature)
price: $1750
Fall 22

Vesuvianite crystals with green outer areas and rose to violet middles. Very lustrous, glassy and well-formed, the crystals are in parallel position and show a cascade of termination faces. In outstanding condition, no visible damage, the crystals are translucent and will glow with backlighting. This looks fine on all sides. From a find over 20 years ago at the famed Jeffrey Mine which had been the source of the world's best Vesuvianite. The mine has been closed for many years and nothing will ever again be produced again. Even though Vesuvianite is not a very rare mineral, these vivid colors and forms do not exist anyplace else on earth. Fine specimens from these unique finds at Jeffrey have become very hard to find, especially in this quality and condition.

Datolite on Prehnite with Calcite
stock #22.1-663
Lane Quarry, Westfield, Hampden Co.
Massachusetts, United States
4.9 x 3.7 x 2.1 CM (miniature)
price: $440
Fall 22

Colorful Northeastern USA classic specimen. From the Lane Quarry (Massachusetts) this is a bright apple -green Prehnite base featuring a sharp, lustrous white Datolite and bright orange Calcites. This Basalt quarry was at one time famed as the source of the world's best Babingtonites, and some of the best Datolites as well. Since then, the Chinese Babingtonites and Russian Datolites have taken those crowns. However colorful combinations like this are unusual and unlike specimens from other world localities. The center is in excellent condition, only minor outer edge roughness is noted.

Fluorite with minor Barite
stock #AX-10-128
McWilliams group near Bouse, Plomosa Mountains, La Paz County
Arizona, United States
4.1 x 2.5 x 2.2 CM (miniature)
price: $90
Fall 22

Fluorite from an uncommon locality, collected about 30 years ago. Zoned blue-grey to purple cubes with the outer edges translucent while the centers are opaque. A good location example, the cubes have some glassy edges but the largest faces are frosted and etched with micro secondary Fluorites clustered in the centers.

Wulfenite - classic USA locality
stock #22.1-499
79 Mine, Hayden, Banner District, Gila County
Arizona, United States
3.7 x 2.3 x 1.6 CM (miniature)
price: $370
Fall 22

Yellow window-pane type Wulfenite crystals sprinkled with colorless Calcite in an attractive array. From the famed 79 Mine, long closed but still a sporadic source of fine mineral specimens. In excellent condition as seen, the Wulfenite is 1.7 CM diagonal, 1.4 CM across the top edge. Displays very well from the front side as shown, the back is also nice but not as attractive. Could be trimmed to a fine thumbnail if desired. A choice Arizona Wulfenite that is transparent, undamaged and with glassy luster.

Epidote - pseudo after twinned Orthoclase
stock #22.1-634
Rusted Revolver Prospect, Orogrande, Otero County
New Mexico, United States
4.1 x 2.9 x 1.7 CM (miniature)
price: $360
Fall 22

A perfect 360 degree specimen of Carlsbad twinned Orthoclase crystal replaced by greenish Epidote. It seems these pseudomorphs are unique in the world, this being the only discovery and locality on the planet. From this recent find in Otero County, New Mexico, this is a textbook clear twinned crystal form and a fine pseudomorph as well. This discovery or possible rediscovery by Erin Deventhal and Phillip Simmonds in late 2020 produced quite a good selection of specimens in all grades. This was selected from the lot as an especially sharp, distinct example with nice color. It is great and satisfying to see new discoveries being made that produce fine specimens.

Wulfenite on gossan matrix
stock #12.1-071
79 Mine, Hayden, Banner District, Gila County
Arizona, United States
4.1 x 2.8 x 1.6 CM (miniature)
price: $250
Fall 22

Classic Arizona locality specimen that is a distinctive and in fine condition. Cute miniature featuring a rosette-like cluster of orange Wulfenite crystals on a contrasting gossan matrix. A few very small additional Wulfenites scattered about are the clear windowpane type and add a little sparkle to the dark host rock. The 79 Mine is famed for a host of important specimens that have trickled out over the years; the Wulfenites took several forms and are an important part of the Arizona mineral heritage. This could easily trim to a fine thumbnail but to me it is fine as is.
