A sharp quartz crystal with thin inclusions of pale green tourmaline crystals running inside. Tourmaline-included quartz is very uncommon from the Himalaya. One face has been polished to better show off the inclusions. A purchase made by Tim Sherburn from the late Josephine Scripps in 1987

Tourmaline on Quartz from Little Three Mine, Ramona, San Diego Co., California, USA [db_pics/pics/ck74b.jpg]

A VERY RARE matrix specimen of tourmaline from this mine, which is highly disrupted geologically and from which really fine large tourmalines are relatively uncommon. On matrix...almost unheard of! This piece features a gemmy 4 x 2.5 x 2.5 cm tourmaline attached solidly to a quartz crystal. It is remarkably unrepaired. The crystal is darker than a Himalaya piece might be in its core, though with a brighter and more transparent termination as are all Little 3 tourmalines, and shows good color when backlit.


CK78 - Paakkonenite in Quartz - $ 250

Paakkonenite in Quartz from Cryo - Genie Mine (Beryl Pocket), Warner Hot Springs, San Diego Co., California, USA [db_pics/pics/ck78a.jpg]

A remarkable and to our knowledge unique specimen recovered in November 2003 while mining the "Beryl Pocket" at the CG. Chris was in attendance and saved this specimen for analysis. It features clearly visible 5 mm-8mm crystals of Paakkonenite in a cluster about 1.5 cm deep in the quartz crystal. The quartz is complete and lustrous on the front side, though contacted on the back and sides. It displays well!

Morganite on Albite and Quartz from White Queen Mine, Pala, San Diego County, California, USA [db_pics/pics/ck90c.jpg]

This important specimen is a rare matrix morganite with crystals to 4 cm, and gemmy at that. They have a brilliant internal brightness to them and a rich peachy color that is really quite unique to the old White Queen material, not matched for 3 decades. This piece would have originated with mine owner Norm Dawson and it has been through several collections in recent decades, most notably Dr. Edward David's first collection (dispersed in 1993) - his numbered label remains on the backside. At some point in the mid-90s it was repaired (cleanly) by dealer Cal Graeber. The repair is invisible unless you know to look for it and runs betweenm the two major crystals so that the crystals themselves are not repaired as such. Matrix morganties from California are rare, but pieces of this calibre are really limited to just a few dozen pieces and most of those are untouchable because they are in museums or priced over 20 thousand dollars these days. This is like owning a piece of history, and is a good investment as they only go up in value.

Quartz with Hematite from Oranje River, Namibia [db_pics/pics/ckorqtz-01c.jpg]

THIS IS A VERY LARGE PIECE! It has a lustrous smoky quartz overgrowth on a nest of rather equant, lustrous and translucent, lavender-colored amethyst crystals. The largest smoky crystal measures 11.0 cm in length. This large specimen is remarkably free of damage, having only some minor contact points on the nesting crystals at the base of the big smokies. The crystallization is shockingly 3-D and 360-degrees. Though the piece is not repaired, the smaller of teh two major crystals was wiggly, and thus Charlie anchored it with a wad of epoxy around its base (not visible unless you hold the piece up and look underneath, anyhow), but I priced this as if it were repaired to be on the fair side. When this specimen is more strongly backlit, it exhibits its rich color of hues of red and lavender.

A milky white quartz crystal has been overgrown by a generation of parallel growth, translucent, hematite included, brownish-red, quartz. The largest of the secondary crystals measures 1.5 cm in length. The color contrast is striking and it LOOKS complex, even though its only a simple pattern repeated endlessly! The net effect is really like no other here, visually. Complete around hte front and right side, contacted in back.

This aesthetic specimen is composed of two large, colorless and translucent quartz crystals. A second generation of hematite-included, gemmy quartz, gives this specimen a lovely glow and slight surface coloration. The larger of the two crystals measures 10.0 cm in length. Complete all around, 360-degree displayable!

RARE FOR THE LOCALITY, this is an INTENSE amethyst specimen with sharp crystals on quartz matrix. Most unusual to get on matrix! These lustrous, rather equant, amethyst crystals are to 6.0 cm in length, complexly intergrown. There is no major damage to the core area, beyond a few trivial dings to secondary crystals. There is some minor edge wear here and there; and peripheral damage around the edges of the specimen, though it is relatively minor in context. The color is intense enough to be called "Siberian", and is really striking and beautiful aside from its significance for the locality - where amethyst of such hue is rare.

A bizarre specimen! A glassy, colorless to milky quartz crystal has been selectively overgrown by a second generation of quartz. The overgrowth is colored brown by included flakes of disseminated hematite but ONLY on the front faces of the crystal and only on the prism faces of the termination. Fascinating for contrast and the sharpness of the separation of color! The back side is a normal style with no inclusions, and is complete all around. It is a floater, with no matrix attachment point. Seems flat on the screen but is really mesmerizing in person

This matrix specimen features about a dozen rather equant, glassy amethyst crystals, to 2.5 cm across. They are "cute" , just perched amidst a nest of clear quartz so smartly. Some of the pristine amethyst crystals are doubly-terminated ; others have formed scepters. The deepest lavender color is centered at the terminations, which has resulted in formation of internal zones and "phantoms." A really fine combination piece, and amethyst is fairly uncommon at this locality as isolated crystals on matrix such as we see here.

This dramatic sceptered quartz crystal has a milky stem sprinkled with hematite specks. A second generation of hematite inclusions has permeated the superb and well developed sceptre head on this specimen. In fact, a close inspection reveals individual hematite flakes within. It is very 3-dimensional and complete all around. Not your every day scepter!

I truly love this dramatic matrix cluster of elongated quartz scepters to 4 inches in height. Extended, colorless stalks give way to glassy, shortened terminal scepters that are lustrous and sharp; and have depth to them caused by the complex layered inclusions of hematite within. Most unusual, are the phantoms created by stems extending into the scepters. A later generation of hematite inclusions has given this specimen a taupe color atop the stalks, contrasting with the darker tips. These crystals reach 10.5 cm in length. Simply, a superb display specimen! It is complete all around on the major crystals, front and back, except for only minor peripheral contact around the base, one small broken crystal near the base; and on the backside a single broken smaller crystal. There is a very, very tight and clean repair about the midpoint that was unknown even to Charlie, hard to spot (but this was priced down accordingly from $2500, even so).

The two-toned effect of the quartz crystals in this cluster is aesthetic and unusual. Originally, the crystals had a milky core and a gemmy termination. A later coating of hematite has given the stems a light tan color while the terminations are still gemmy. The longest crystal is 7.5 cm and at the interface of the stem and termination is a superb phantom!

This is on its own merits a gorgeous multicolored specimen has matrix of massive quartz as the host for a cluster of discrete, extremely sharp , prismatic quartz crystals. It is also ILLUSTRATED IN THE NAMIBIAN MINERALS MAGNUM OPUS, by Rainer Bode, page 734. Internally the crystals are gemmy, and color ranges from colorless to amethyst-purple. A later generation of growth contains rich hematite inclusions, with an unusually rich reddish-brown color and superb luster. This combination has embodied these crystals with incredible colors. The largest crystal measures 7.0 cm in length. No damage to the display face! It is also MUCH more eye-poppingly 3-dimensional in person. There is only a contact to the last crystal on the far left, on the back of the display face; and a tiny Wilber on the back side of the termination of the largest crystal. It is large, and has great visual presence.
