1.8 x 0.9 x 0.6 cm. A stunning thumbnail tourmaline from Nigeria, absolutely TOP gem quality from top to bottom, with a beautiful range of color captured pretty well in the photos. It has a fine termination on one end.
6.3 x 2.8 x 2.4 cm. An UNUSUAL and showy, doubly terminated green tourmaline from the famous Cruzeiro Mine of Brazil. This is a highly lustrous crystal. One termination is lighter green, translucent and is etched, fibrous. The other, pinacoid, is matte, very dark green. Excellent, old-time material from a famous pegmatite. 71 grams.
7.1 x 1.2 x 1.2 cm. A GORGEOUS, gemmy and lustrous, doubly terminated, parallel-growth, renowned "hot" pink tourmaline from the famous, but lesser-known Stewart Mine of California. Ex. George Elling Collection. 20 grams.
3.2 x 1.3 x 1.3 cm. A sculptural, blunt-nose, rocketship-like, sceptered tourmaline from the famous Pederneira Mine of Brazil. The "rocketship" is a gemmy, indicolite/teal blue, while the "flames" are pink. The blunt-nose pinacoid termination is lustrous and nubby.
4.7 x 1.5 x 1.4 cm. A MOST UNUSUAL, gemmy and lustrous, etched, pink tourmaline with a deep raspberry-red termination. This weird looking, but showy crystal hails from the famous Santa Rosa Mine of Brazil. Classic, older material, seldom available. 14 grams.
8.2 x 2.4 x 1.2 cm. A LARGE (94-gram), translucent green tourmaline crystal from Mozambique, out of the Elling Collection. This crystal is doubly-terminated - the end that once was the "broken off" end has formed microfaces, indicating that the crystal broke off in the pocket and was able to "heal" on the broken end (where there is actually a bit of BLUE color).
13.4 x 4.4 x 3.8 cm. This HUGE tourmaline crystal (424 grams!) out of the Elling Collection is actually very dark GREEN, not black as it appears. It is just so thick that the light cannot get through (unless you put it under very strong light, and then you can see into the surface and see the bottle-green color). It is complete all around and terminated.
6.3 x 1.8 x 1.6 cm. This is a translucent-to-transparent tourmaline crystal, with a superb, glassy termination on top, from Pakistan. It has bright, grassy green color and is particularly gemmy towards the termination - more milky and achroic at the center. This fine crystal weighs 35 grams. Early material from the 1980s. Ex. Eugene Sensel collection.
4.2 x 4.1 x 3.9 cm. A cluster of tourmaline crystals, tightly intergrown and all terminated separately, out of the collection of the venerable Fred Pough. All the terminations are complete save one that is tallest and evidently contacted the pocket wall. In very strong light you can see that these are actually gemmy, but the color is a very dark green. This is an old piece out of the Saurs Mine in Gouvernador Valadares.
5.4 x 2.1 x 1.7 cm. A fine, sizeable gem tourmaline out of the Elling Collection, whose appearance suggests that it is from the 1960s finds there. The color is absolutely remarkable: it has a wonderful gemmy green at the top, and the bottom is a bright teal color!
5.9 x 1.3 x 1.1 cm. A fine tourmaline crystal that is UNUSUALLY gemmy for the Himalaya - and doubly-terminated, as well! At one end is a typical flat termination, and the other is a jagged, multiple termination. The crystal grades from a smoky green to a wonderful gemmy bright pink for most of its length. Weighs 15 grams.
9.0 x 0.7 x 0.6 cm. A CUTTING QUALITY gem crystal of tourmaline from the Pederneira Mine - long, slender and elegant. This crystal is flawless and top gem quality from top to bottom, with bottle-green color that is classic for this mine. It is terminated on the top end, as well. Weighs 8 grams.
2.7 x 0.8 x 0.8 cm. A beautiful, gemmy and lustrous, pink-tipped tourmaline with a green body from the famous Cruzeiro Mine of Brazil. Classic, older Cruzeiro material with a nice, complex pyramidal termination. 17.91 carats or 3.58 grams.
3.2 x 1.2 x 1.1 cm. A CLASSIC, BEAUTIFUL and RARE old-timer from the famous Golconda Mine of a pristine, gemmy, sceptered, doubly terminated tourmaline. The body is a beautiful indicolite blue and the sceptered cap is green. 6 grams.
7.2 x 3.4 x 2.5 cm. A DRAMATIC, multi-axis, aesthetic tourmaline cluster from the famed Golconda Mine. The lustrous, partially gemmy, green crystals have beautiful, yellow highlights and all of the major crystals are pristine. The long crystal is etched, as is another basal crystal.
