Cubanite twinned crystals
1.6 x 1.2 x .4 CM (thumbnail)
A sharp and lustrous thumbnail in exceptional condition. Clean twinned crystals with classic form and bright striations. Classic material from the Henderson #2 mine at Chibougamau which has been closed for years but once produced the finest Cubanites ever seen. Good value for form and quality.
A remarkable series of colorful, sharp and lustrous Anglesites reaching 3.1 cm in a stacked cluster. Matrix includes Balydonite and Mimetite among other unidentified species. The Anglesites show the bi-pyramidal form and have yellow, greenish and orange-brown inclusions along with typical milky white areas. Both unusual and very attractive, an outstanding lead secondary specimen from the amazing Tsumeb!
Sapo Mine, Goiabeira
6.3 x 3.8 x 3.3 CM (cabinet)
Bi-colored and very lustrous Apatites are clustered in a stacked grouping that is a perfect floater (crystallized all around). No damage and displayable from any angle, this 2010 vintage Sapo Mine piece is similar in form to some Alpine cleft type specimens. Sapo has produced many interesting and attractive habits and colors over the years, this is quite distinctive and more impressive in person.
Small but intense rich purple Vesuvianite with magenta and dark green areas. The color is deeper and more intense than the computer monitor can render well. The luster is glass-like and the specimen clearly has two generations of growth. Some of the smaller crystals show hoppered terminations. The "matrix" is a blocky crystal of Vesuvianite that shows signs of being recrystallized as well. This is the most uncommon color found at Jeffrey and essentially unknown from any other locale.
An extraordinary fine small cabinet specimen with exceptional form from Batopilas. For esthetics and delicacy of crystals, there is no other location like the Batopilas area of Mexico. This piece is very far above average and is in perfect condition. Individual leafy crystals over 3.3 CM tall show many sharp, fine treelike side growths in many habits. Far better in person and offering lots of display impact this is a choice modern classic.
Grossular with minor Natrolite
Jeffrey Mine, Asbestos
3.4 x 3.3 x 2.2 CM (small miniature/ large thumbnail (toenail))
A good specimen of a type that is becoming hard to find and often very expensive. This has a nice presentation overall but has damage to some smaller crystals and with magnification more chipping is seen, so it is not for perfectionists. Good value for color, luster and contrast with the light matrix. Shows good isolation of the Garnets too. Far less expensive than an ultra perfect specimen but in normal display looks just as nice.
A single crystal of Anglesite in the pointed habit that has had some dissolution pockets near the base that are now filled with crystallized Arsentsumebite and Mottramite. Nice color contrast and a pearly luster on the Anglesite add character. Some minor bruises exist at 10 magnification these look like typical bruising but at 40X magnification it seems some of this is partly recrystallized so these are more likely semi-healed old in-situ damage or contacts. A nice piece with a rather uncommon association.
Lustrous oil-green prisms are well presented on the contrasting Actinolite. From a less well known Northeastern US locality (the Ore Hill Mine, Warren, NH) Ex Bob Whitmore collection, the condition is excellent. Choice piece from an uncommon locale.
