An unusual and cute Canadian Garnet specimen from the Orford Mine. A 1.7 CM honey-brown Grossular is resting on and included by crystals of Diopside. The Orford Mine is well-known as the source of Chrome green Grossular and Diopside specimens. The usual Grossular from here are micros rarely reaching up to 3mm in size, typically forming a sparkling druse. Larger crystals like this are very rare, I do not know of another this large and complete.
A fine, large doubly terminated Apatite crystal sits on an orange Calcite matrix. The Apatite is well-formed with the typical slightly rounded edges and two different types of termination. Fluorapatites are fairly common in the scattered Skarns of this region but substantial crystals like this are not found very often. There are some minor contacts but overall this is a distinctive textbook form crystal with some areas of glassy luster. A modern classic.
Two different forms of Fluorite on Calcite matrix sprinkled with Chalcopyrite crystals. The Fluorite cubes are very sharp, gemmy zoned and vividly fluorescent. The pink portions of the Calcite are also fluorescent making a nice contrast of purple, red and cream colors. The Fluorite cubes are up to 8mm in size and in perfect condition. The cores are a yellow hue with a blue outer zone. We almost never see this locality represented in Fluorite collections but it is clear it was capable of forming some very nice crystals.
The Madoc area of Ontario, Canada is well-known for unusual Fluorites, some of the best in all of Canada. This specimen has an unusual mix of colors which also vary depending on the light source from a yellowish to green and orange to an unusual pinkish hue. It seems there are inclusions on some internal planes that add color and help to refract light. Some faces are slightly frosted but others are very lustrous, the edges are very sharp and the whole is transparent to translucent. The bottom is contacted but the crystal above that zone has very nice form. These better Canadian Fluorites are not available for sale very often, this was collected more than 20 years ago. It is still possible to find Fluorite in this area but good pieces are very rare.
Super brilliant luster on these deep blue crystals. A modern classic from Rapid Creek in the Yukon considered by many as the world's best of the specie. These crystals are in a rich cluster, well-developed, very sharp and show good separation. The Quartz crystals are also very sharp and gem clear. A nice contrast. In any good lighting the color is especially bright and rich. In very good condition overall though not perfect, there are some tiny bruises found on close exam (loupe) that are not very noticeable. This does keep the cost much lower and yet looks like a far more expensive piece. The backside is also crystalized but is more Quartz with less Lazulite. A fine display piece.
Cubanite twin crystals in a cluster with virtually no matrix. In fine condition as seen, such good Cubanite crystals have become quite rare as it has been over two decades since the last of this world class find. This one shows excellent golden luster and form, the largest crystal is a full sixling twin. It is very unlikely there will ever be more of this quality found. There are several localities in the world for this mineral but any crystals are very rare and almost all are micros. These Canadian specimens are the by a wide margin the best in the world, and good twins are especially scarce now.

An unusual habit from this famed Canadian locale, a spherical rosette of small bladed crystals hosts a cluster of larger twinned Selenites. I have been informed that at one time some pieces were heated or baked to make this selective white areas on the golden selenite, so this is not fully natural but human modified. Not sure why this was done as the golden color is quite nice on its own but theoverall effect is esthetic in a different way. Overall this looks fine from any angle. The crystals are a golden to orange-yellow color except at the terminations which are a milky white. In fine condition, we have handled a lot of Selenite from this locale but this piece is quite different in style. As is usual for Selenite from the Red River this is strongly fluorescent.
Several sharp Zircons are well-exposed from the classic MSH matrix. The largest Zircon here is 1.4 CM across which is huge for the locality and these crystals are very well-defined. Most of the larger Zircon we have seen from Mont St. Hilaire tend to be much more crude than this. Vividly Fluorescent and in fine undamaged condition.
