6.8 x 4.4 x 3.3 cm. This is a fine, old Russian amethyst of the Richard Hauck Collection. It is a phantom, with the internal crystal having the purple color isolated at the tip rather than saturated throughout the crystal, making it really unique and beautiful.
17.2 x 3.3 x 3.3 cm. An impressive South African smoky quartz crystal. It is striking for both its transparency and its size. It is complete all around, with good luster. It has a complex, complete termination it goes from smoky to milky at the termination. Good luster, with gently striated faces.
8.9 x 5.9 x 2.4 cm. This is an unusual quartz specimen. The crystals have this bizarre flattened and bent form. The crystals are doubly-terminated - the terminations are complete and nearly perfect. The crystals are strikingly transparent and glossy, and arranged in a beautiful "V". At the bottom of the "V" is a square tabular crystal.
22.9 x 7.4 x 6.4 cm. A large and superb quartz crystal out of the Wein Collection. This large crystal looks like a column of cut glass. It is absolutely glassy-transparent through the center. The incredibly complex faces make it a bit hard to appreciate the clarity and fineness of this crystal, but it is truly amazing. And, in fact, it is these "cut glass" modifications that make the crystal so unique and aesthetic.
4.8 x 3.7 x 1.8 cm. A fabulous floater Herkimer quartz (these are often called "Herkimer Diamonds" due to their brilliance). Two intergrown crystals show the incredible clarity that makes these so famous. You can see the typical dark inclusions of bituminous inside. The larger crystal is absolutely glass-clear.
8.4 x 6.9 x 5.4 cm. In an open pocket in a matrix of limonite is this glowing cluster of deep robin’s-egg blue chrysocolla lit up by a sparkly covering of drusy quartz. The chrysocolla is nestled inside the vug in which it formed, on a bed of contrasting velvety, deep grey quartz. Ex. Terry Szenics Collection.
3.4 x 2.8 x 1.4 cm. A wonderfully clear, heart-shaped floater crystal of quartz, shot through in back with little crystals of black schorl tourmaline.
10.5 x 4.9 x 2.3 cm. This is a strange flattened smoky quartz crystal, complete all the way around except for one end. One of the large faces is richly shot through with dozens of slender schorl crystals.
10.9 x 6.8 x 6.7 cm. A large and fine combination specimen from Panasqueira. Gemmy quartz crystals, long and slender, have been wrapped in a blanket of olive-colored muscovite - with their glass-clear tips sticking out at the ends. The quartzes are surrounded by three large, translucent green apatites (the largest measures 3.5 cm across).
8.8 x 7.4 x 6.4 cm. These crystals of green quartz, with their gently tapering form and inclusions of acicular (hair-like) crystals of hedenbergite, are classic from the Greek island of Seriphos. Most often, you see matrix-free clusters of a few crystals. Here, you have dozens of crystals, on matrix. Ex. Richard Hauck Collection.
18.4 x 14.8 x 5.4 cm. A very large and extremely striking specimen of quartz out of the Richard Hauck Collection - most notable for the fact that you have a very large anchoring crystal that has grown right around another very large, doubly-terminated crystal - like a tree branch growing around a fence pole. On the lower part of the main crystal is another long, slender, doubly-terminated crystal.
5.4 x 4.9 x 4.4 cm. From the Namibian side of the Orange River, a cluster of crystals of glassy quartz, which get their color from rich inclusions of hematite.
3.9 x 2.4 x 1.9 cm. This fine Orange River specimen is a sharp phantom - you can clearly see the razor-sharp crystal inside that was coated in hematite - then engulfed by a later generation of growth.
4.9 x 1.8 x 1.4 cm. A fine Orange River red quartz specimen - this, a fine single crystal with a phantom inside just barely contained by a later growth of clear quartz.
6.9 x 5.5 x 3.9 cm. From a new find in Namibia, a very unusual specimen of lovely lavender-blue chalcedony.
