8.6 x 6.2 x 2.1 cm. Two perfectly crossed crystals of gemmy quartz, both doubly-terminated - in fact, all the crystals here are terminated - it is a complete floater cluster of fine, undamaged crystals! There are some dark mineral inclusions here and there within the cluster.
9.9 x 7.3 x 6.5 cm. A big, gorgeous crystal of smoky quartz, with a somewhat orangey-citrine tone rather than gray, from Brazil. The faces have GLASSY luster, and the transparency is just fantastic. This crystal has naturally truncated, more Herkimer-like form - it is not "broken off" at the bottom - that is the natural contact face where it grew against the matrix.
4.8 x 2.8 x 2.6 cm. An old-time, unusual and showy pseudomorph from the famed Felsobanya (Baia Sprie) mines of Romania of metallic-bright pyrite after silver crystals richly and 3-dimensionally covering quartz matrix. This is a rare pseudo from this famous and soon to close locality. Accompanied by an old Schortmann’s label. Ex. George Elling Collection.
6.4 x 4.7 x 4.4 cm. What a wonderfully aesthetic specimen from Eastern Europe! The Borieva Mine has a way of turning out gorgeous specimens of rather common minerals. Here, you have a fine balance of silky quartz crystals sticking up from amongst silky, sharp, finely-formed galena crystals with a "brushed metal" look.
4.9 x 3.7 x 2.8 cm. Collectors love these specimens of chrysocolla from Arizona that have a covering of sparkly quartz, which makes the whole surface a glittery robin’s-egg blue. This specimen features the added attraction of small bursts of tiny gemmy malachite crystals!
5.3 x 3.3 x 2.9 cm. A cluster of gemmy amethyst crystals with a light pastel purple blush, very nicely trimmed and very aesthetic, from this famous amethyst locality.
12.5 x 7.0 x 6.8 cm. This is a very interesting Connecticut old-timer. It features a group of larger, milky quartz crystals with a separate generation of slender actinolite crystals that were pseudomorphed by quartz. The pseudomorphs are now hollow tubes, with the actinolite gone but the quartz "casts" remaining.
5.8 x 5.6 x 4.0 cm. Hematite and quartz combo specimens from England are just about as classic as you can get. This one features a cluster of beta-style quartz crystals, combining frosty faces with lustrous ones, on a bed of bladed hematite crystals that formed on the surface of massive hematite. The quartz crystals, as you can see, are intergrown in a complex and aesthetic way. They have a slightly smoky tone.
14.5 x 8.9 x 2.6 cm. A very showy, old-time German CABINET specimen of slabbed and polished "coral" agate from near Leipzig in the Erzgebirge. The orange-red band is striking, but I particularly like the brecciated inner-core of the agate on the lower left, where the partially solidified agate fragmented and then continued growing. This is a classic locality for fine German agate.
4.0 x 2.1 x 2.0 cm. Lustrous anatase crystals to 1.2 cm are artfully embedded on and in a beautiful, water-clear smoky quartz crystal from Hardangervidda, Norway. The striking, large anatase, partially on and in the smoky is certainly the focal point of this very showy specimen. Dr. Hansen obviously prized this specimen, which he obtained in a small lot trade with the Smithsonian, who in turn traded with the Geology Museum at the University of Oslo.
3.7 x 3.5 x 2.3 cm. Lustrous, dark green paratacamite crystals floor a glassy, quartz-lined cavernous vug in beautifully contrasting powder-blue chrysocolla in this striking and gorgeous specimen from the Lily Mine of Peru. Paratacamite is a rare copper chloride and this is a super piece.
If I had to pick one miniature for sheer pizzazz, this would be it. The specimen features a really fine aqua with deep color, excellent glassy lustre, and complete all around....but its those associations that obviously make it outstanding and visually unique! Never have I seen a miniature from here with such interesting and unusual aesthetics, because of its associations with schorl and quartz. This full miniature is complete all around! 5.2 x 4.1 x 2.7 cm
A stellar cluster of upright aquamarines, complete all around 360-degrees, that is perched smack on top of crystals of smoky quartz. Its amazing, really, that it grew this way and survived! The aquas are majestic, how they reach up to a multilevelled termination. It look slike a cityscape on a mountain! 6.1 x 5.2 x 4.7 cm
Great combination piece with several aquas perched amidst a cluster of smoky quartz! The larger aqua is 2.5 cm and has a sceptred termination pointing front. The smaller aqua is about 2 cm and features a stunning, gemmy, sharply bevelled prismatic termination. The piece as a whole is very bright and 3-dimensional. 6.25 x 4.9 x 3.0 cm

15.2 x 13.4 x 6.4 cm. A BIG specimen of a collector favorite from Arizona. In this case, instead of being on chrysocolla, the sparkly quartz crystals are on a layer of malachite, which is in turn on a layer of chrysocolla. These are usually seen in small specimens, but the area of crystallization here measures 12 cm in length - this is basically a big pocket that was removed intact! This is an old-timer, and hard to find, especially in a specimen this large and rich! Probably 40 years out of the ground, this one.
