OKD-305 Dioptase Tsumeb, S. W. Africa. Ex. Nancy Collins Collection. Add some flash to your mineral display…this brilliant green specimen is composed of sharply formed crystals to .7 cm each. They are intergrown and form waves crystals thickly coating the majority of the piece. There is only one small contact area which makes this specimen almost stalactitic in form. Zero damage even under magnification. 6.8 x 3.5 x 3 cm overall. Outstanding specimen. 280$

OKE-369 Natrolite Ice River Complex, Yoho National Park, British Columbia, Canada. Ex. Steve Chamberlain Collection, Prev. Canadian Museum of Nature, 1982. This is an exceptionally rare specimen that is not for everyone. It is a 2.8 cm double terminated crystal.

OKE-371 Fluorite on Quartz RESERVED Francon Quarry, Montreal, Quebec, Canada. Ex. Steve Chamberlain Collection, Prev. FIGURED SPECIMEN in the German publication Mineralieu Welt (Mineral World) in the early 1990s. I do not have the article but assume this specimen took a fine pic (hopefully better than mine!). The purple fluorites are almost micro and coat the majority of the parallel growth sceptered quartz. A fine TN specimen which Dr. Chamberlain collected from the now closed quarry in 1977. A fine, damage free, aesthetic specimen. 2 x 1.5 x .9 cm overall. 295$

OKE-372 Prehnite RESERVED Jeffrey Mine, Asbestos, Quebec, Canada. Ex. Steve Chamberlain Collection. Perhaps one of the best Jeffrey Mine TN specimen I have seen! This cluster is a complete, damage free floater. Tiny sprays of natriolite as an accessory can be seen between these fine, translucent, light green crystals of prehnite. Every crystal is double terminated and in spectacular form. Nice prehnites from this location are not commonplace. 2.9 x 2.6 x 2.1 cm. Another competition grade piece. I’d expect this specimen to be triple this price with most other dealers. 195$

OKE-373 Weloganite Francon Quarry, Montreal, Quebec, Canada. Ex. Steve Chamberlain Collection. Great Mineralogical Record issue dedicated to this now permanently closed locality (Ref. Min. Record Jan- Feb. 2006, Vol # 37, No. 1). Exceptional specimen in all regards…2.9 cm ranks this as very large for this rare species, which is from its type locality. The luster, translucence and yellow color are all top of the line. This particular crystal is the largest I have ever owned and the only one I would describe as being double terminated. There is a tiny contact on one termination where it may have been loosely connected to matrix. Minor white coating is likely Franconite (also type locality for the species). Amazing single crystal with a couple of very tiny rider crystals. Specimen has more of a yellow color than the photo indicates. One of the finest TN specimens I have ever owned. 600$

OKE-374 Weloganite Francon Quarry, Montreal, Quebec, Canada. Ex. Steve Chamberlain Collection. Great Mineralogical Record issue dedicated to this now permanently closed locality (Ref. Min. Record Jan- Feb. 2006, Vol # 37, No. 1). WOW! These crystals always seem to be a small crystal with a huge chunk of non-trimable matrix or with no matrix at all. This is one of only a couple I have ever seen which has large crystals and minor (just the right amount) of matrix. There are several large crystals here, to 1.6 cm each in crude parallel growth. Rare growth zoning and unknowns here too. Small clear crystals on the weloganites and tiny black spots that are who knows what. Specimen has more of a yellow color than the photo indicates. Piece measures 2.7 x 2.7 x 2.1 cm. Zero damage. Amazing TN specimen!

OKE-375 Natrolite on Analcime De Mix Quarry, Mt. St-Hilaire, Quebec, Canada. Ex. Dr. Steve Chamberlain Collection. Beautiful aesthetics displayed in this piece. Nicely formed translucent natrolites stand up vertically off an analcime ball. Minor arfvedsonite. Very neat! No damage in a matrix contact so small you will have to search with magnification to find it. 2.9 x 1.5 x 1.5 cm. This one should go fast. 95$

Canadian Museum of Nature Collection Stuning contrast of crystal shapes and color make this a highly aesthetic and desirable specimen. One natrolite appears to not be terminated but I find no damage to anything else in this wild mix. 3.5 x 2.5 x 2 cm. I’ll let the images speak for the quality of this specimen. 250$
