A fine white, loose, complete crystal that is doubly-terminated and possibly twinned. ex. American Museum of Natural History , Clarence Bement collection, donated in 1910 (label is present, just not shown)
Although diopside crystals can grow larger from other deposits, there is no doubt that these are the gemmiest in the world, but few from here reach this massive size! This particularly large crystal is not only transparent but has a beautiful greenish color similar to brazilianite. It weighs 50 grams, and although contacted on the back and one side, when properly displayed shows no damage in the display faces. A very rare example of a very common mineral in exceptional form! This is one of the best I have seen for sale out there .
A sharp single crystal showing unusually intense green color and gemminess for this OLD CLASSIC locale. This piece was self-collected at the location by Skip Szenics in 1967 when he rediscovered the veins (which had been "lost" for over 50 years). Written up in the Lapidary Journal in the late 1960s, this was a significant discovery and remains the last time that major crystals were found here. Then, the piece went into the Joe Cilen collection
ex. Robert Whitmore
This crystal of diopside is actually verging on unprecedented quality for the location , both for size and for the combination of color and lustre that makes it not so ugly as most from here. It is large, complete, and really dramaticÖand again, just not ugly despite the size and locale. An important piece, collected by Robert Whitmore long ago.
Sharp, very gemmy, pear-green crystals of diopside to nearly 2 cm spray out from a graphite matrix. The lustre and glassiness of the crystals is remarkable, as is their perch on contrasting (and seldom preserved) matrix.
A plate of GEMMY diopside crystals to 2 cm, some of them in rows with staggered terminations, from Afghanistan. These can sometimes be very dark green and not all that transparent, but these are really glassy!
1.4 x 0.7 x 0.7 cm. A CHINESE gem crystal of diopside - VERY gemmy in fact, with good luster, complete all around and terminated. It has a fine light grass green color.
6.5 x 6.2 x 2.9 cm. Unbelievable 3 1/2 cm vein of gemmy deep-green Chomian Diopside. From the classic locality in Finland.
7.4 x 6.4 x 3.0 cm. A 3.2 cm, highly lustrous and partially gemmy, emerald-green, chromium diopside crystal in a chromium diopside and quartz matrix from Aracuai, Brazil. Very few of these came out a number of years ago and this a highly representative specimen of this species and locality. Ex. George Elling Collection, circa 1960s.
5.6 x 3.8 x 3.4 cm. These specimens came out about 6 years ago. The piece features unusual modified honey-golden colored crystals of Grossular associated with rich green (possible Chromium-bearing), gemmy prisms of Diopside on limestone matrix. Ex. Richard Kosnar Collection.
5.7 x 5.2 x 4.0 cm. Gemmy and lustrous, orange-red, garnets to 9 mm are aesthetically scattered on a 3-dimensional matrix of olive-green diopside crystals on this CLASSIC and VERY FINE piece from the famous Eden Mills Mine of Vermont. Henry Minot specimen.
7.3 x 5.7 x 5.2 cm. A showy, old-time and excellent combination specimen from the famous Thetford Mines of Quebec of bright green, chrome, grossular garnets aesthetically nested on a jackstraw matrix of lustrous, translucent to opaque, tan to green, diopside prisms. An excellent, old piece from the George Elling Collection.
2.4 x 0.3 x 0.3 cm, 2.2 x 0.3 x 0.3 cm, 2.1 x 0.3 x 0.2 cm, 1.9 x 0.3 x 0.2 cm.
Four TERMINATED gem crystals of "chrome diopside", so named because of the high chromium content that gives the crystals their green color. The crystals are gemmy and have good luster.
9.2 x 4.9 x 2.7 cm. For all its prodigious production of mineral specimens, the Gilgit area is not known for its diopsides, and particularly of this size: a crystal measuring 4 cm tall by 2.5 cm wide! It is TERMINATED and complete all around - jutting out of matrix, with a sidecar crystal on one side (also terminated). The crystal has a pretty grass-green color, and is translucent. very unusual specimen, I would say.
5.0 x 2.3 x 2.3 cm. A fine white, loose, complete crystal that is doubly-terminated and possibly twinned. Ex. American Museum of Natural History, Clarence Bement collection, donated in 1910.
