6.3 x 2.6 x 2.1 cm. Lustrous anatase crystals to 3 mm are artfully embedded on and in a beautiful, water-clear smoky quartz crystal from Hardangervidda, Norway. Most of the anatase crystals are on two sides of the smoky and are the focal point of this very showy specimen. The main sidecar crystal at the base is fully terminated. Dr. Hansen obtained this piece in a small lot trade with the Smithsonian, who in turn traded with the Geology Museum at the University of Oslo.
7.0 x 5.0 x 3.5 cm. A showy and excellent Chinese combination specimen of gemmy and lustrous, orange spessartine garnets richly scattered and nicely intermixed on 3-dimensional feldspar matrix with upright, glassy smoky quartz crystals and a muscovite book from recent finds at Tongbei. The fat, glassy smoky in the front is 1.8 cm and the one broken smoky in the back, middle is out of sight. The base has been sawed to enhance display.
16.9 x 4.4 x 3.4 cm. This is a huge, doubly-terminated, super-gemmy quartz crystal from a find in Pakistan, distinctive in that the crystals have this wonderful, bizarre natural etching that gives their surface a sort of "cut-glass" look. There are sharp, jagged diamond etch pits all everywhere. And yet, the etching did not take away from the brightness of the crystal - the surface is still quite lustrous and gives a nice clear view into the wonderfully transparent interior.
4.4 x 3.2 x 2.9 cm. A rounded cluster of gemmy apophyllite nestled against a stilbite crystal that is covered (as the area around it) with grayish quartz - creating a pretty contrast with the apophyllite.
13.1 x 3.6 x 3.4 cm. A large, complete stalactite of quartz, with no contacts or damage and the tip intact and crystal-covered, from Uruguay. Most of these are amethystine, and it is actually more unusual to see one of colorless quartz. The bottom, where the stalactite was sliced off, has been polished to show the concentric deposition rings of the core and the radiating pattern of the crystals that grew on it.
5.6 x 4.4 x 3.1 cm. An absolutely fabulous smoky quartz mini - the quality is just superb. It has the bright intensity of a good Swiss one! And, the form is so aesthetic - a compound crystal of three beta-type forms, with a couple of skeletal areas. Gemmy as can be, and the luster is like GLASS. Contact only on the back side where removed from the matrix.
3.4 x 3.1 x 1.9 cm. Look at the superb gemminess of this rose quartz specimen! Rose quartz is the most prized of the quartz varietals, and specimens of this quality are EXCEEDINGLY rare - that is, specimens with very well-defined, elongated crystals that have this exceptional transparency. You could hardly do better for a miniature of rose quartz!
6.2 x 3.1 x 1.6 cm. This crystal amply demonstrates why Brandberg amethysts are so highly valued by collectors - the super clarity and subtle purple interior "blush". In this case, it is an actual phantom, with quite a clear outline in person!
15.2 x 10.8 x 6.9 cm. From an exciting find in China around 2 years ago -- wonderful green epidote crystals on clusters of quartz. I had some of them from the first discovery, but they all sold, so I was thrilled to get my hands on some more from a second large pocket hit there not too long afterwards (many of them even more richly decorated with epidote crystals!). They are all gone now, as far as I know. This is a superb representative of the find, with fine gemmy quartzes beautifully isolated. A good-sized piece as well. Definitely at the very top for this find – this specimen has it all!
4.5 x 3 x 2.5 cm. Two shiny-metallic, flattened spinel-twinned crystals, with sharp pyramidal form, leaning back on a matrix covered with gemmy quartz crystals. The specimen was shot from the front so you cannot see that these spinel twins are very thin and platy, with faces on both sides. A fine Eastern Euro mini!
8.2 x 5.3 x 5.0 cm. A “crown” of pretty rose quartz, the most rare and sought-after quartz varietal, on a matrix of quartz and feldspar. Aesthetic piece, overall, with good color.
9.3 x 6.0 x 5.3 cm. An EXCELLENT and SHOWY specimen of quartz replacing wulfenite crystals on sparkly, gray, drusy quartz-covered matrix from the famous Finch Mine of Arizona. The large crystal is 7 mm. I particularly like the separated, tiered vugs and shape of the matrix; it looks like a spear-point or ship’s bow. This is one of the rarest Arizona replacement specimens available on the market.
3.8 x 2.1 x 1.6 cm. An UNUSUAL and UNIQUE fossil from Holbrook, Arizona! This is a polished slice from vanadium-rich petrified tree limb. The unique green color is caused by vanadium and the bark on the outer rind is very well preserved. The piece is probably from the famous Petrified Forest.
11.4 x 6.1 x 3.0 cm. A CLASSIC, OLD-TIME Japanese CABINET specimen from the 1800s! The plate is covered with sculptural, curtain-like, en-echelon, bubbly chalcedony. The light gray, translucent chalcedony has a very pleasing texture. The old label is glued to the bottom of a 10.7 x 9.2 cm wooden box! Really an antique artifact in itself. This showy, old-timer is from the Ogasawara Islands, near Tokyo.
4.0 x 3.3 x 1.0 cm. An aesthetic cockscomb of spinel-twinned silver wires jauntily projecting upward from milky quartz matrix. This showy specimen is from Fresnillo Mexico and comes with an older label. The bit of quartz perched on a silver wire is a neat accent. Spinel-twinned silver from Fresnillo is not that common and this is a good one. Ex. George Elling Collection.
