8 x 2.8 x 2.4 cm. An elegant and lustrous 8 cm Schorl crystal. The finest features are the crystalline fans that splay outward, adding a level of drama and beauty not often found with a Schorl. The white coating, hyalite opal, adds a beautiful contrast and flair to the sides, back, and termination. Ex. Charlie Key stock.
7.6 x 4.8 x 3.6 cm. A superb Aquamarine/Schorl combination specimen from the Erongo Mountains. The Schorls, for the most part, are lustrous and sharp. The triangular section attached to the large Aquamarine, is just that - a section. But it adds an aesthetic complement by its shape, position, and healed surfaces. The main Aquamarine, 3.2 x 2.3 cm, is amazing. It is almost completely gemmy, which, for its size, is exceptional. The color is a deeper blue than you normally find from Erongo, and the crystal faces are highly lustrous with a ''watery'' texture that reminds one of a lustrous Heliodor/Aquamarine that has been slightly etched. The termination is perfect, and even includes small, penetrating Schorls. Ex. Charlie Key.
5.2 x 2.6 x 2.1 cm. Opal is one of those minerals that look as beautiful and impressive when it is opaque as when it is water clear. The amazing range of this material (considering the simplistic chemistry) makes it an interesting mineral, especially considering that the species does not even have any crystal form. The Opal from this Gracious O Dios Mine, Honduras, have been mined for over 150 years, and have proven to be some of the more attractive yet lesser known from the Western Hemisphere. This piece features a few very attractive patches of multicolor Opal on matrix which shows flashes of red, gold, orange, blue and green. Ex. Brian Kosnar Collection.
4 x 4 x 2.4 cm. An aesthetic and unusual cluster of prismatic Schorl crystals, with some of the Schorls capped by highly fluorescent Hyalite Opal. The Schorl crystals are slender and have superb luster. You do not often see this particular habit in such a well-defined cluster, with equally good and large (over 2 cm) crystals. Ex. Charlie Key.
3.1 x 2.8 x 2.1 cm. Opal is one of those minerals that looks as beautiful and impressive when it is opaque as when it is water clear. The amazing range of this material (considering the simplistic chemistry) makes it an interesting mineral, and that's saying a lot considering the species does not even have any crystal form. The Opal from this Gracious O Dios Mine have been mined for over 150 years, and have proven to be some of the more attractive yet lesser known from the Western Hemisphere. This piece features a few very attractive patches of multicolor Opal on matrix which shows flashes of red, gold, orange, blue and green. Ex. Brian Kosnar Collection.
11.2 x 5.2 x 3.0 cm. This is a natural piece of boulder opal, showing a literal "stream" of opal running through classic matrix. When you talk about opal in its natural rock setting, you almost always are referring to the classic look of these pieces. However, most are jumbly nodules and lack the interesting, pattern-like aesthetics of the opal as it flows in this specimen. Buffed, obviously, to show the opal to advantage, this specimen has a good balance of color in the rock and shows how the stuff forms in nature. Weighs 286 grams.
3.6 x 3.0 x 2.0 cm. Opal a mineral that is as beautiful and impressive when it is opaque as when it is water clear. The amazing range of this material (considering the simplistic chemistry) makes it an interesting mineral, and that's saying a lot considering the species does not even have any crystal form. The Opal from this Gracious O Dios Mine have been mined for over 150 years, and have proven to be some of the more attractive yet lesser known from the Western Hemisphere. This piece features a few very attractive patches of multicolor Opal on matrix which shows flashes of red, gold, orange, blue and green. Ex. Brian Kosnar Collection.
12.8 x 7.8 x 4.8 cm. What makes this combination specimen of schorl and aquamarine special is that it also contains two spear-like crystals of smoky quartz, to 4.5 cm in length. Quartz seems rare in this pocket at least. Furthermore, this plate of feldspar matrix is smothered by lustrous, black schorl crystals to 2.75 cm across; and a bevy of glassy and gemmy, intensely-colored, blue aquamarine crystals to 4.0 cm in length. Finally, the right side of the specimen is coated liberally by hyalite opal. From the new find of late summer 2009.
7.8 x 6.3 x 2.4 cm. Lightning Ridge opal is world-renowned for quality and color and this slabbed and polished section of boulder opal is a striking example. This is a vintage specimen of "precious opal" in matrix. The polished color play of peacock blues, greens and whites is absolutely spectacular against the variably brown matrix. Weighs 180 grams or 900 carats. Ex. Duncan Elliott Collection.
8 x 6 x 4 cm. This is a fine matrix piece of superb Aquamarines with gemmy lustre and intense Erongo-blue color. They stand upright and stark against a matrix of partially etched Orthoclase, capped in places by highly fluorescent Hyalite Opal overgrowth. The Aquamarines are terrific - excellent color and luster, gemmy terminations, and the largest is 5 cm tall. The termination, on its right side, shows a secondary growth: a thin layer of slightly different colored aquamarine atop the main core. Ex. Charlie Key.
11.5 x 7.3 x 6.5 cm. A starkly dramatic, superb cluster of five complete, prismatic crystals of Orthoclase from the Erongo Mountains. About four years ago, a number of prismatic Orthoclase crystals associated with Fluorite came out. However, none of the feldspars that reached the market compared with this specimen. The longest crystal is 8.5 cm long, and there is a generous coating of Hyalite Opal. A great specimen in form, quality, and aesthetics. So sharp, it looks carved. Ex. Charlie Key.
10.8 x 8 x 3 cm. Absolutely one of the finest Schorl specimens I have ever seen from the Erongo Mountains. Every single crystal in this large 10 cm plate has superb luster and incredibly sharp form. It is even complete-all-around, though covered with hyalite opal on the backside. The crystals range from .5 cm up to 2.5 cm. Ex. Charlie Key.
10 x 7 x 7 cm. An exceptional combination piece of unusual, and very attractive, stark white Orthoclase crystals intergrown with gemmy Smoky Quartz and Schorl needles. All on granite, with a small amount of Hyalite Opal as a bonus: an incredible fluorescent accent. The Orthoclase crystals are tabular, with the largest ones being 3.5 cm, and twinned. The gemmy Smoky Quartzes are more on the order of 1 cm, as are the Schorls. I've not quite seen the likes of this specimen before. It is a great piece from a famous location, but more than that it is just unusual from anywhere, in its overall aspect. Ex. Charlie Key.
1.7 x 1.6 x 1.0 cm. Opal is one of those minerals that look as beautiful and impressive when it is opaque as when it is water clear. The amazing range of this material (considering the simplistic chemistry) makes it an interesting mineral, and that's saying a lot considering the species does not even have any crystal form. Recently, I obtained a small parcel of precious Opal from Honduras, The Opal from this Gracious O Dios Mine have been mined for over 150 years, and have proven to be some of the more attractive yet lesser known from the Western Hemisphere. This piece features a very attractive little patch of multicolor Opal on matrix which shows flashes of red, gold, orange, blue and green. Ex. Brian Kosnar Collection.
3.8 x 3.6 x 1.8 cm. A classic, symmetrical and beautiful opalized mollusk from the Coober Pedy Opal Field of South Australia. This lightly buffed specimen has real color to it, with bright flashes of candy apple-blue, -green and subtle hints of orange, which really sets this distinctive fossil off. This is an excellent and above-average sized opalized mollusk from this well-known locale. It is very visibly colorful and translucent.
