4.8 x 4.4 x 3.0 cm. A truly elegant Vera Cruz amethyst specimen, with two crystals in a beautifully balanced cross, on a wonderfully trimmed matrix. There are smaller crystals as well; all are very gemmy and fine, and all terminations are complete.
15.4 x 11.2 x 3.3 cm. This quartz specimen is just so beautiful you can see why Ed David had it in his fine collection. It is a plate of botryoidal, translucent, dove-grey quartz with a rippling surface and elegant, sculptural form. This style of quartz was not common at all from India! Ex. Ed David Collection.
20.1 x 16.8 x 8.9 cm. A BIG plate of amethyst crystals from Vera Cruz! This is a ribbon of light pastel lavender, gemmy crystals, to just over 2 cm, running across the middle of the matrix, with some lighter crystals surrounding them.
3.9 x 2.5 x 1.8 cm. A rare Pack Rat Mine specimen of a slightly smoky quartz crystal that has grown right around a schorl crystal and terminated in two peaks on either side! One of the schorl terminations is complete. Ex. Chuck Houser Collection.
10.1 x 8.4 x 4.8 cm. A sizeable plate richly covered with a fine balance of gemmy little orange spessartines and sharp prisms of smoky quartz! The spessartines are climbing part-way up the smokies, dressing them up nicely. They measure to 4.5 cm.
12.0 x 10.6 x 5.0 cm. This is just incredible quartz for anywhere, but it is truly remarkable for an American specimen. It is a BIG, super-gemmy crystal that is a complete FLOATER, with no contacts or damage - and, it is doubly-terminated, with multiple terminations on one end. It has a very unusual and interesting truncated form, as well. Fine, glassy luster.
2.9 x 2.9 x 2.4 cm. A classic Panasqueira combo of intensely gemmy quartz with a ferberite crystal, its termination tilted perfectly to create a sensational display face in association with the quartz and minor siderite.
7.9 x 7.7 x 6.9 cm. Arkansas quartz is common, but NOT like this! Having spent time at the mines and known plenty of others who have, I have personally not seen or heard of anyone finding a spectacular gemmy crystal with stepped side faces (rare enough alone) that is crowned by a complete, doubly-terminated gemmy crystal on top.
6.3 x 3.0 x 2.5 cm. A spectacular example, even better in person, of pristine, intensely bright and gemmy amethyst from Brandberg - like no other amethyst in the world. It has these wonderful subtle blushes of purple inside, and you can even see little bright red crystals of lepidocrocite included inside! There are three crystals here growing in parallel.
7.2 x 4.6 x 3.4 cm. Uncommon on that market, this is an old New Hampshire specimen of smoky quartz crystals in association with orthoclase (the same combination that appears in specimens from Colorado, with the orthoclase being usually in the form of blue "amazonite" in that case). The orthoclase here appears as both blocky crystals and piled-up clusters of smaller crystals. The smokies are of superb quality - gemmy and with glassy luster!
16.2 x 10.7 x 9.5 cm. This whopper crystal is fine Bolivian amethyst, not common Brazilian! IN person, it is much prettier - suffused with rich purple color, particularly the top inch or two, which is super-gemmy and brilliant. This beauty weighs 3.5 pounds!
5.5 x 3.4 x 3.4 cm. These quartzes are sometimes called "Herkimer diamonds" due to their unusual clarity and high luster. They are found in cavities in large, hard boulders at the Herkimer locality. This is a complete floater, with no contacts or damage, terminated on both ends (multiply terminated on one end). It has the bituminous inclusions that you commonly see with these.
8.4 x 6.4 x 5.7 cm. A large, dramatic ball of glistening, sparkly white dolomite, from Eastern Europe. It has engulfed some quartz crystals, which you can see poking out from its surface. The tan stuff is minor siderite.
8.4 x 8.4 x 2.1 cm, 8.4 x 8.41.9 cm. In case you have not noticed, agates from around the world have over the past few years suddenly begun to gain respect amongst even serious collectors. This is a rare specimen from the desert of Morocco, with one area in which crystals have grown together solidly, and another of pale blue-gray non-crystalline agate laced with threads of a rusty iron-rich mineral.
5.7 x 2.8 x 0.6 cm. This crystal group exhibits the classic "Faden" (German word for string) form that is well known from this area. The piece exhibits a very striking "Faden" that runs through the length of the superb, sharp, highly lustrous, GEM quality crystals that create this highly aesthetic, three-dimensional group.
