10.9 x 9.4 x 4.1 cm. A terrific smoky specimen from right outside of Fresno, California - so take note all you Cali collectors! It is actually a lot better in person than the pic shows. What you have is a very large compound crystal (flat contact where it met the pocket wall on the back) with complete, multiple terminations on either end! To one side is attached a cluster of smaller crystals, also with complex compound structure. The large compound crystal has a fine luster that does not come through in the photos - it is not dull or coated! You just do not see many smokies of this caliber on the market from this area - it looks (in its size and complexity at least) more like something from Brazil or Pakistan.
13.4 x 9.4 x 6.6 cm. There are two large quartz crystals on this specimen, one of them a distinct sceptre. They are attached to a cluster of white, euhedral feldspar crystals, out of which poke two aquamarines - a small one on the front of the specimen, and a pristine gemmy one of 2 cm sticking out of the side. The relatively sharp crystals of feldspar instead of the usual blobby matrix make add distinction to this specimen.
16.9 x 10.9 x 6.9 cm. There are actually THREE Japan Law twins on this cabinet-sized specimen from the Daye Mine in China! The largest of them has a "wingspan" of 6 cm. They are set on a broad plate of massive quartz with prismatic crystals around the twins. Japan Law Twins from this mine are NOT common on the market, and this one is pretty darned major! All three twins are in fine shape - there is only one extremely small nick at the top of one of them. The Daye Mine has been producing a broad array of collector-quality specimens of various minerals for some time now but good twins remain rare.
13.4 x 8.9 x 7.9 cm. A large, very ornate compound crystal of amethyst from the Rift Valley in Kenya - of TOP quality. You can see the beautiful repetition of the crystal form along the display face, basically a sort of turbo-sceptering. There is good transparency into the face, and a pretty variegation between clear and a wonderful soft lavender color. You can see some natural ragged stepped areas. What you cannot see is the nice luster - just did not come through in the photo. A really sizeable crystal, too!
19.4 x 5.4 x 5.4 cm. A huge quartz crystal, a REVERSE SCEPTRE, with natural etching that makes it really interesting. There are euhedral notches and stepping everywhere. At the termination are greenish inclusions of fluorite. The interior of the crystal from top to bottom is very gemmy!
7.9 x 4.5 x 2.5 cm. A sharp spinel twinned galena stands up dramatically in the midst of a cluster of quartz crystals with an orange color from a later generation of small calcites. I like how the spinel twin is isolated and showcased on this impressive Eastern European specimen.
17.6 x 3.9 x 3.4 cm. A stunning example of a highly sought-after locality piece! This New Mexico quartz crystal is not only of rare large size for the locality, it is also of SWISS quality. It is gemmy, super lustrous and razor-sharp, with smoky hues in blushes in the clear interior. About half-way down is a very clear phantom. The top half is pristine, with the typical contacts and a smaller crystal attachment on the lower half.
13.9 x 12.4 x 6.9 cm. That white "crystal" atop this large plate of amethyst from Morocco is not what it appears to be. What you are looking at is an eggshell-thin cast of quartz that formed around a calcite crystal, retaining its form perfectly after the calcite inside was etched away by corrosive solutions in the pocket. There is a little peephole that lets you look inside. What a stunning pseudomorph, and perched right up there on a perfect setting! A very unusual specimen, not something that came out in quantity from this locality.
6.8 x 3.8 x 2.4 cm. Crystals of green tourmaline shooting through a gemmy crystal of quartz like swords through a stone! When these come out, the tourmalines are usually bashed up pretty badly, but these are in unusually good shape. There are even some complete terminations, which is not common since the terminations cannot usually be preserved when these are taken out. The tourmalines are cutter-quality gem material, the longest measuring almost 4 cm, with one of its terminations intact! A very dramatic specimen!
12.1 x 4.0 x 2.4 cm. This extremely unusual quartz specimen is probably some variation of a faden; you can see a fuzzy line running along what constitutes its "spine". At any rate, off of this spine gemmy crystals are stacked and fanned in a most aesthetic way. You can see some minor chlorite inclusions. Quite a unique quartz!
2.9 x 1.7 x 1.4 cm, 2.6 x 2.4 x 1.7 cm. These fantastic "Herkimer-style" quartz crystals came from GILGIT, of all places. Look at the quality! They are like jewels, and what makes them really cool are the inclusions. Something has given them these areas of pretty acid yellow color. And, inside both crystals are pockets of water with moving bubbles inside ("enhydros") which makes them even more wonderful!
8.9 x 6.1 x 4.5 cm. You might be familiar with the wonderful translucent, spherical yellow fluorites from here that are prized by collectors. But here is a large one (3.75 cm across) that is wrapped in lustrous amethyst crystals - adding even more appeal! Extremely rare association!
8.6 x 5.4 x 4.9 cm. This specimen shows the galena spinel-twins in their more chunky form (as opposed to the flattish form the other exemplifies). These crystals (to 2.4 cm) have a fine luster and are razor-sharp.
8.9 x 6.9 x 5.9 cm. A cluster of quartz crystals with unique amethystine OUTLINES around the edges - uncommon for Brandberg, or for anywhere for that matter! In one place, the quartz has grown around some super-sharp euhedral feldspar crystals. Ex. Charlie Key Collection.
3.7 x 2.5 x 1.6 cm, 3.4 x 2.4 x 1.4 cm. A "matched pair" of orange and amethystine quartz "doubles" from Namibia! Each of these minis is fabulous for what it is. The orange crystal pair has super-sharp orange (hematite) phantoms inside; the amethystine pair has Brandberg-like blushes of intense color. Both are gorgeous, and side by side, they make such an impressive set!
