8.0 x 5.1 x 3.0 cm. A doubly-terminated crystal of quartz on dolomite, with a very interesting phantom inside that appears to be a broken earlier termination of the crystal, which was engulfed by the crystal as it grew later and came to a new and perfect termination.
4.8 x 3.2 x 2.5 cm. A gorgeous and complex sceptred amethyst/smoky from Brandberg out of the Charlie Key collection. The amethyst/smoky compound crystal has formed around a central anchoring crystal of milky quartz. Fine luster, and wonderful balance of purple and smoky tones.
7.6 x 3.3 x 2.6 cm. A showy, lustrous, doubly terminated gray smoky quartz crystal preferentially coated with bertandite crystals and a couple rhodochrosite crystals from the Kounrad Massif of Kazakhstan. An excellent combination specimen.
5.9 x 3.9 x 2.7 cm. This combo is an English classic. There are three gemmy quartz crystals here, containing bright rust-red inclusions of hematite, on a field of sparkly black specular hematite. A fine and pretty representative mini for this combo, ex. Russell Jones Collection.
15.4 x 14.4 x 7.2 cm. Green fluorite covered with scalenohedral crystals of calcite that have been pseudomorphed by microcrystalline quartz. We photographed it with a light behind it so that you can see that this thick piece is nearly solid fluorite, mixed with some veins of quartz.
10.1 x 8.9 x 6.4 cm. Tongbei is still cranking out these marvelous spessartine/smokies. Not many are of this quality, however, with the garnets ISOLATED on the contrasting feldspar, so that they jump out at you like little jewels. There are four good smokies sticking up as accents. The size here is impressive as well!
5.6 x 3.5 x 3.2 cm. Gemmy and lustrous, orange spessartine garnets richly cover matrix and preferentially coat the large, upright smoky quartz crystal on this showy and excellent specimen from the Tongbei Area of China.
4.6 x 3.0 x 2.7 cm. A very rich and showy specimen of hackly, copper-coated gold profusely set in an aesthetic column of milky quartz from the famous 16 to 1 Mine of California. Quite a bit of gold here. Weighs in at 52 grams or 1.8 ounces.
6.7 x 5.6 x 3.3 cm. A MAJOR and showy stannite specimen richly covered with lustrous, discrete crystals and nicely complimented by water-clear quartz crystals and even a 1.0 cm fluorite cube.
Charlie thought this was perhaps the best specimen around,using the phrase "off the charts," and I can say I have not seen better. It wsa supposedly found about 30-40 years ago. It features dozens of SHARP, wine-red crystals of this very rare thallium-rich species that also has a smorgasboard of other elements in it. Here we have several dozen large-for-species crystals to 4 mm. 6.8 x 6.6 x 3.8 cm
5.4 x 4.4 x 3.0 cm. An unusually attractive specimen featuring a silky quartz crystal nestled amongst dark green epidotes, with most of their terminations complete. From a small find of about 2003.
5.8 x 3.8 x 3.2 cm. A MOST UNUSUAL and SHOWY box work of elongated, lustrous, brown calcite rhombs preferentially coated with drusy quartz and capped by a couple of small apophyllite crystals from Jalgaon, India. This visual piece is a complete, undamaged floater!
11.5 x 6.0 x 4.0 cm. CABINET-SIZED specimens of Red Cloud wulfenite were never common. This very showy 2003 Red Gem Pocket piece is dominated by a beautiful, centrally located, 1.1 cm, gemmy and lustrous, red-orange wulfenite crystal with smaller crystals nicely scattered on the quartz matrix, which is uncommon in itself.
7.4 x 5.1 x 3.4 cm. A gemmy quartz crystal, shot through with needles of acicular rutile - much as you would see in Brazilian ones, but these crystals are a very dark gemmy smoky color, rather than the golden color of the Brazilian ones.
5.3 x 4.0 x 2.4 cm. This amazing Brandberg quartz crystal has so much going on! It has both amethystine and smoky hues, and in addition to having both regular sceptres AND reverse sceptres, it is doubly-terminated (albeit with a few contacts). Who could ask for anything more in a single quartz specimen!
