8.1 x 6.0 x 3.7 cm. This is an incredibly thick "book" of microscopically thin sheets of phlogopite mica from Canada - it is hard to imagine how many are in this 3.3-cm thick stack. You can see the sharp hexagonal outline clearly here, the dark, smoky color, and the high reflectivity.
6.1 x 3.2 x 3 cm. A superb pair of intergrown Diopside crystals with a beautiful forest green color. The luster is excellent, and the outer portions of the Diopside are actually gemmy, which creates an attractive variegated look to the color. The main termination is sharp and lustrous. The main crystal is 6.1 cm long. Ex. Charlie Key.
4.6 x 2.7 x 2.3 cm. A superb and classic combination miniature from a historic Italian locality - Testa Ciarva, Piedmont. This very aesthetic piece is studded with gemmy and lustrous, red to orange grossular garnets and is beautifully highlighted by the single, 5 mm grossular on the central, column-like spray of glassy, pastel-green diopside crystals.
5.9 x 2.5 x 1.5 cm. Though it is only translucent and certainly not a gem, this is a huge crystal for the species in terms of crystals that are not just plain opaque. Also, it is complete and terminated on top, with the typical steep termination. Weighs 59 grams.
8.1 x 5.3 x 3.1 cm. Here is a fine European Alpine "classic". One of the most recognized associations from the Alps are the beautiful green and red Diopside and Grossular combinations from Italy. This piece features dozens of sharp, lustrous, gemmy, bright, reddish-orange color trapezohedral crystals of Grossular (variety: "Hessonite") with very light green (nearly colorless) crystals of Diopside with dark bluish-green "rosettes" of Clinochlore. This piece was collected in 1985. Ex. Richard Kosnar Collection.
3.5 x 1.4 x 1.2 cm. A gemmy and lustrous, complete all-around, green diopside crystal with a sharp, etched pyramidal termination from the 2002 finds at the Kunlun Mountains of China. This fine crystal was illustrated on Page 280, Fig. 15 of Vol. 34, #3, the May-June, 2003 Mineralogical Record issue. 11 grams. A superb example from this one-time, rare find.
6.8 x 4.4 x 3.3 cm. An excellent specimen from the Jeffrey Mine. An aesthetic cluster of very gemmy and lustrous, pastel-pink grossular garnets to 1.2 cm are nicely framed by green diopside and snow-white pectolite crystals. All of the garnets in the 3.5 cm long cluster are pristine. Pink Jeffrey garnets are not that common and this is a highly representative example of the species in nice combination.
5.4 x 0.3 x 0.3 cm. A slender, gemmy, doubly-terminated crystal of chromian diopside from a recent find in Pakistan. It is the chromium that gives these crystals their rich green color (as with so called "chrome" tourmalines and other gem crystals that get their green color from chromium content).
6.9 x 3.7 x 3.1 cm. This unusual specimen is a very attractive, shimmering cluster of violet-colored diopside crystals, from a new find in early 2008. I picked this up on a trade from a collector at Munich who says he got it from the original collector in Munich as well, and that it was the best of the lot for size/aesthetics balance. I had not seen others, so I will trust him on this. Most unusual.
An attractive and brilliantly colorful specimen showcasing 3 classic Italian minerals on one beautiful cabinet-sized matrix! The gorgeous major crystal is about 1 cm across, and there are dozens of smaller crystals blanketing most of the display face, with only trivial damage here and there that certainly does not detract. The associated clinochlore and green diopside accentuate the burgundy-red color of these bright and lustrous garnet crystals. 7.5 x 6 x 4 cm
4.3 x 3.3 x 1.9 cm. This is a large, really high quality crystal with deep color and a large translucent zone. The terminations are broad, lustrous, and well-developed, much more than you normally see for large diopsides from this classic locale. It is about 50 grams. This is a superb single crystal.
7.4 x 7.1 x 4.2 cm. Because it is a cluster, and large, this is a really good example of this rare replacement. Grossular garnet has completely replaced a former epidote crystal cluster (floater, with the largest crystal 7 cm and doubly-terminated). On the grossular, later-formed diopside crystals have grown. The whole thing was encased in, and dissolved out of, calcite by the collector (Ken Hollman). Ex. Ken Hollman Collection.
1.8 x 1.3 x 1.1 cm. A fine, little thumbnail specimen. Ex. Ken Hollman Collection.
An unusual, elonagated crystal with striking gradation of color from the top to bottom! This is likely an old specimen, and certainly is from an old classic locality. It is an unusual gem crystal guaranteed to fool folks into thinking it is a weird spodumene or hiddenite! 7.3 x 0.8 x 0.8 cm
1.6 x 1.4 x 0.9 cm. A classic and fine Eden Mills thumbnail from the Dick Jones Collection. A 1.1 cm, gemmy and lustrous, reddish-orange, complete-all-around and pristine, grossular garnet is perched on a diopside crystal. The grossular has textbook, dodecahedral form. Older material.
