Serandite with Analcime
Poudrette Quarry, Mont Saint-Hilaire
3.7 x 2.6 x 1.4 CM (miniature)
pre Tucson 2015 update
A sharp salmon-pink Serandite crystal is almost completely covered with small, sparkling gem clear analcimes much like a coating of ice. The few larger Analcimes growing from some faces are the typical milky white and are a nice contrast to the Serandite. A very nice example from mining over 30 years ago at Mt St Hillaire. Excellent condition.
Calcite over Stibnite
Quincy Mine, Hancock, Houghton County
7 x 5.2 x 6.2 CM (cabinet)
An odd, strangely attractive specimen with an interesting form, This is a series of fingerlike growths studded with scalenohedral calcite crystals. These have grown over slender crystals of Stibnite which are now completely covered by the reddish calcite. It is possible to see on the bottom where this was broken off the Stibnites remain.
A very distinctive thumbnail with excellent crystal form that is typical of fine alpine Prehnite. Ex. Wendy Melanson's great thumbnail collection, her locale lists Cavradi Gorge Tavetsch, however it is likely that this came from Tavetsch but maybe not in Cavradi itself, but it right for that area. No matter what this is an elegant piece showing well crystallized colorless "pinwheel" forms in an attractive 3 dimensional arrangement. No damage, great luster.
