Diopside- Chromian green with Grossular
Orford Nickel Mine, Brompton Lake, Sherbrooke
5.9 x 4.4 x 4.2 CM (cabinet)
The so called Chromian Diopsides from the famed Orford Nickel mine are quite prized. We are told that the color may be due to Nickel and not Chrome but either way these are very attractive and uncommon. This one has unusually fine apple green hue. The largest crystal is 1.7 CM and all are gemmy with very glassy luster. Normally the larger crystals are opaque, and a yellowish to grey color. Such bright green clear crystals are usually only microscopic. Tiny deep green Grossular are also present as are Calcite crystals. The tiny crystals add a lot of sparkle in person.
