10.9 x 9.9 x 7.1 cm. This is a huge quartz crystal with glass-clear faces that give a window into a scenic "garden" in the interior, consisting of sericite, chlorite and little thin needles of schorl tourmaline. Ex. J.R. Glover Collection. This is spectacular, like a garden inside!!! . The interior looks almost like a mossy hill with new snow on it! These "picture quartzes" from Brazil are really unique and fascinating, but so many of them are polished because the natural faces are not in good shape. This one is both in its natural state, and unusually large!
11.9 x 10.9 x 2.4 cm. A complete, spherical "flower" of amethyst from Brazil - a rosette lifted cleanly from the copper-rich matrix, leaving only a few dots of green on the back side. There are hundreds of tightly intergrown crystals here, with delicate blushes of purple on the ones towards the interior. It is flashy and lustrous, too.
6.2 x 4.9 x 3.4 cm. A pearly, light salmon-pink crystal of stilbite, with smaller crystals around it, juts up from a beautifully contrasting matrix of drusy, light grey quartz. This specimen was trimmed out just right to strike a fine balance between the pretty stilbites and the matrix.
5.9 x 3.9 x 3.1 cm. A rich specimen of the rarest and most prized quartz varietal. These are BIG crystals for rose quartz, to over 2 cm - with pretty pastel color, good transparency and fine luster as well.
6.3 x 2.9 x 1.7 cm. The form of this Brandberg quartz out of the Charlie Key collection is so unusual - it is just SUCH a unique quartz specimen. What you have here looks as if an amethyst crystal swallowed a smoky Herkimer! The middle, smoky section shows skeletal growth; the purple ends have the usual bright clarity and pretty purple blush these are famous for. it is more striking in person - hard to capture in pics, but truly bizarre.
4.7 x 3.6 x 3.2 cm. This is a very large and lustrous schorl crystal from Erongo, terminated and complete, but what makes it unusually attractive is this gemmy, glassy, doubly-terminated quartz crystal embedded right in its face!
10.1 x 1.8 x 1.4 cm. Some phantoms are hard to make out. Then there are crystals like this - WOW! The quartz crystal inside was richly included with red chlorite before being engulfed by later growth and becoming this incredibly striking phantom crystal. There is some small angled-back damage to the termination on top, but it is the phantom that matters here anyway and the piece is showy as heck, if not pristine as you wish. This is an old and well known find from the early 1990s, and specimens are uncommon today.
4.0 x 2.5 x 2.0 cm. An excellent and very showy combination specimen from the well-known find of blocky, highly lustrous and partially gemmy, deep red heubnerite crystals aesthetically set amongst jackstraw, water-clear quartz needles from the Victoria Mine at Mundo Nuevo, Peru. The Victoria Mine closed in 1974. This pristine and beautiful specimen is from the Brent Lockhart Collection, who purchased this piece from the Zweibels in 1983. Seldom available in this quality today.
4.7 x 3.8 x 3.0 cm. A RARE and BEAUTIFUL radial spray of white strontianite needles from a very famous locality - Cavradi, Switzerland. I have never seen such a good one for sale from here. A very small area of broken crystals is noted, but is certainly not a major detraction to this fine piece. The characteristic transparent, flattened, 2.3 cm quartz blade on the back proves this piece is from Cavradi and not from Illinois, as I would have initially thought. Ex. Brent Lockhart Collection.
7.2 x 4.1 x 3.7 cm. A showy and excellent combination specimen of quartz crystal sprays aesthetically set on matrix RICHLY covered with tiny, pastel-pink, flattened rhodochrosite rhombs. This is CLASSIC material from the famous Boldut Mine at Cavnic, Romania. This is a fine representation of the species and locality, not withstanding the couple of broken quartz crystals in the large spray. We have heard that the famous Maramures County mines may be closing soon.
3.9 x 2.5 x 1.5 cm. A UNIQUE amethyst quartz crystal from a most unusual and NEW African locality - the Kaiiado District of Kenya. This HIGHLY UNUSUAL, very glassy and transparent crystal looks like an elongated, cubic fluorite crystal with a stem. It looks like a tooth with a root. I have never seen anything like this except a few oddballs from Herkimer in New York (and those had no color)! It has very sharp cubic faces, modified corners and even has a V-shaped phantom, visible when looking down onto the specimen. There are smoky quartz overtones in the cube. All in all, a really WEIRD and VERY SHOWY piece! The miners called these "fluorite-quartzes", they were so puzzled.
4.5 x 4.5 x 2.5 cm. A really cute and nifty Indian specimen. A pearlescent, doubly terminated stilbite crystal "caps" a lustrous, salmon-pink heulandite crystal, which rests on a crust of chalcedony. The overall composition is very pleasing and aesthetic. Choice material from the George Feist Collection, #2403.
6.5 x 4.3 x 3.5 cm. A CLASSIC, OLD-TIME and EXCELLENT combination specimen from the famous Wheal Gorland of Cornwall. Lustrous bundles of teal, acicular clinoclase (so intensely colored they were mistaken for connellite by me) compliment and contrast lustrous, green olivenite needles with glassy quartz crystals in a very colorful vug in coarse milky quartz. Specimens of this RARE combination and quality came out in the mid 18th century and are much desired.
8.4 x 6.4 x 3.3 cm. A fine example of the Chalcedony pseudomorphs after Fluorite from Blinkpan. The crystal form remains very sharp, and the attractive banding in the matrix adds even more to the overall aesthetics. Ex. Charlie Key stock.
11 x 9 x 6 cm. The green Erongo Fluorites have become famous in their own right, but to find them in such superb combination with the rare and desirable clear Goshenite Beryls, as well as Smoky Quartz, is a thing to behold. Both the Fluorites and Beryls range up to 2 cm, and the Smoky about 3 cm. The luster on the fluorites is silky and very good, as is the gemminess and zoned coloration. The Beryls have superb luster. Overall, this is an incredible combination piece - one of the best I have seen from this region. Ex. Charlie Key stock.
