QUARTZ19 - Quartz Var. Amethyst Scepter
$ 395.00
SOLD NET
Ashaway Village, Hopkinton, Rhode Island
small cabinet - 8.2 x 2.9 x 2.6 cm

This interesting deposit is in southern Rhode Island. The crystal form exhibits an interesting primary white Quartz crystal (clear core), with a lavender/purple scepter head secondary growth. I've taken pics to illustrate this effect. These crystals are found in loose dirt, as they were carried down from their original pegmatite by glaciers. Mining of this site has been for one day per year, for the last 10+ years. It comes with a custom made, lucite base. It's in fine condition, with only the tiniest Wilbur on the backside of the termination. An eye-catching scepter from a hard-to-find location.

QUARTZ20 - Quartz Var. Herkimer Diamond Cluster
$ 235.00
SOLD
Ace of Diamonds Mine, Herkimer County, New York
miniature - 4.4 x 3.3 x 2.1 cm

This bright, clear cluster of Herkimer Diamonds was mined by my good friend Tom Dillon. He does all the work at the Ace of Diamond mines. This super gemmy example of a reconstructed cluster is a fine example of the ledge material. At this mine there is a pocket layer that involves 2 weeks of hard labor to remove overburden, and produces pockets with larger Herks that are usually included. Then there is the ledge, much more accesible, but very hard to break (silicified Dolomite). The pockets are quite small, but the crystals are usually very clear. The hard work can pay off with a gem of a cluster such as this one. It is 5 individuals (plus one small extra). This is a complete cluster, meaning all the crystals that originally grew together remain together. It's in great shape, without dings, and only a few small patches of contact where it grew within the Dolomite.

QUARTZ21 - Quartz Var. Smoky Amethyst Scepter
$ 650.00
SOLD
Peterson Mountain, Foster Hallman Claim, Hallelujah Junction, Nevada
cabinet - 10.8 x 6 x 5 cm

This fine crystal is in pristine condition, without any dings, including a super sharp termination. It has a purple depth of color to it, which is unusual in scepters from this location. We've mined at this deposit over the last 20 years, and the amethyst is typically next door at Jonne's claim, while more smoky scepters are found at Foster hallman's claim.  A deep purple, large  scepter is the holy grail for this location and few have ever been found. This scepter sits so perfectly on its lucite stand, The head is very symmetrical, and the stem is centered. From the backside, you can see the layered crystallization, where the top growth contained the Amethyst. It has character and charm.

TOPAZ7 - Topaz Var. Imperial
$ 3250.00
SOLD NET
Ouro Preto, Minas Gerais, Brazil
small cabinet - 6.6 x 2.2 x 1.6 cm

This crystal is a stunner! It came out of Peter Bancroft's collection (no label) It is very bright and gemmy and has great color. The termination is a thing of beauty for anyone who's seen a lot of imperial topaz crystals, it's pristine and well defined. It has its own lucite base. There is one small chip along one edge below the termination, and slightly longer one lower down on the crystal (seen in third pic). This are minor and easily overlooked for such a bright Topaz.

SOLD NET
Las Velhaus Mine, Minas Gerais, Brazil

This extraordinary Tourmaline is bi-color and clean. It has a multi-termination, with the top third being a salmon/orange color and the rest is a teal blue indicolite. There are no dings or damage, just the back side near the base it is rough where they extracted the crystal from its pocket. It looks fantastic in its custom lucite base. Given its internal clarity the crystal appears to glow from within regardless of lighting. It was grabbed immediately from our Hawthorneden stock when we first acquired their inventory, and we just got it back from Steve Dowell. It weighs 31 grams.

CALCITE7 - Calcite Var. Cobaltian w/ Kolwezite
$ 695.00
SOLD
Mupine Mine, Kolwezi, Katanga Copper Crescent, Katanga (Shaba), Democratic Republic of Congo (Zaïre)
cabinet - 13.5 x 8.5 x 3.4 cm

Scalenohedral calcite crystals up to 2.5 cm long are dusted with boytroidal Kolwezite. Kolwezite is (Cu, Co)2 CO3 (OH)2, found in the oxidized copper zone of this type locality, it is the same formula as Malachite, with Cobalt added. This piece could be described as Cobaltian Calcite with Cobaltian Malachite. (The custom made lucite base reads "Cobaltian Calcite with Malachite," for this reason). The piece is in fine condition, without any visible dings. The pink color of such large crystals is eye-catching, and the green Kolwezite adds a pleasant contrast. It comes from Gilbert Gauthier's collection from Maisons-Laffite France (see pic of label).

Benitoite w/ Neptunite on Natrolite from Benitoite Gem Mine, San Benito County, California [db_pics/pics/benitoite1a.jpg] Benitoite w/ Neptunite on Natrolite from Benitoite Gem Mine, San Benito County, California [db_pics/pics/benitoite1b.jpg] Benitoite w/ Neptunite on Natrolite from Benitoite Gem Mine, San Benito County, California [db_pics/pics/benitoite1c.jpg] Benitoite w/ Neptunite on Natrolite from Benitoite Gem Mine, San Benito County, California [db_pics/pics/benitoite1d.jpg]



BENITOITE1 - Benitoite w/ Neptunite on Natrolite
$ 1395.00
SOLD
Benitoite Gem Mine, San Benito County, California
thumbnail - 6.6 x 5.6 x 2.5 cm

Benitoites come from a now closed mine in California. This dynamic specimen aesthetically combines these three classic minerals. There are over 20 Benitoite crystals on the piece. Two Neptunites jut off the matrix at different angles, and the Natrolite forms a white relief, underneath. There is a neat stack of Benitoites that occur as they've crystallized on a ridge of the matrix. The "stack," is about 2 cm long, and has the largest crystals of the piece on it (.9 cm an edge) Overall fine condition, with the only damage being one of the Neptunites has a rough top, whereas the other is well terminated. Overall, this is a fine piece especially in terms of aesthetic composition.

TOURM23 - Tourmaline var. Elbaite
$ 695.00
SOLD NET
Mt. Mica, Paris, Maine
small cabinet - 5.6 x 5.0 x 4.0 cm

This is a classic Maine tourmaline. It was found within the last 4 to 5 years. It has a blue-green color that is typical of Mt. Mica. It is aesthetically pleasing, especially with the feldspar that accents the termination. I must say it has a "Devil's Tower," look to it (Richard Dreyfuss could have used it in Close Encounters of the third kind). It comes with its original priced label from Leonard Himes ($950), who is a partner with the mine owner. It has some miner scuffing on the backside (fourth pic), and just a little on the front edge of the termination. It weighs 185 grams.

$ 1250.00
SOLD
Santa Maria Mine, Minas Gerais, Brazil

This substantial Indicolite has excellent color, and is in pristine condition without any dings. It weighs 69.7 grams. It has a slightly greenish termination that is super sharp. There are small spherical muscovites attached around the termination. It comes in its own custom made lucite base. It's a little "loose," when placed in the base, so a little ball of hot glue is placed under the crystal.
