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.
Intense green small Grossular are scattered on greenish to grey color Diopside. From the Orford Nickel mine, these were called Uvarovite for many years, and this has an old label with that name but this is absolutely all grossular. These are still occasionally found at this venerable locale, but this piece has especially bright green color and larger than typical garnets. Choice for the locale, and an esthetic combo. Collected by Les Hitchings in 1967.
A very big blocky Diopside crystal that is a perfectly formed, has a good color and some translucence. Ex Steve Chamberlain, A. Edwards, and Canning collections, this is remarkably perfect, undamaged and about as clean as can be. Several faces show complex growth patters and have a nice silky luster. Choice for the specie and excellent for the locale.
Bright green Diopside with emerald green micro Grossular in an esthetic cluster from the famed Orford Mines. The Orford Nickle mines produced some excellent Diopside crystals but mostly grey or pale green in color. These very bright green crystals were often called "Chromian" for the color, but now are considered to be colored by Nickle instead. No matter the source these are an especially rich green and this specimen has many well formed, sharp and esthetic prisms to 1.5 CM tall. Very attractive and quite rare.
