Siderite on Quartz from Redruth, Cornwall, England [db_pics/pics/bem-19c.jpg]

A superb competition-level miniature featuring a fanspray of thin, translucent siderite crystals to 4 cm, perched upon a knoll of sparkling white quartz! The aesthetics are great for any siderite from any locality, and the significance of the large crystals from this particular historic location is also a bonus to the intrinsic quality for the species. From the miniature rarities suite of Lawrence Conklin. Almost certainly found in the mid to late 1800s and remarkably, despite its apparent fragility, preserved intact since. This is complete all around and displays from both sides.

The scheelite is exceptional for Zinnwald ...this is CLASSIC old scheelite from a classic locality, with crystals to 9mm, perched on a terminated quartz shard. This is very beautiful and aesthetic!. ex. American Museum of Natural History and shows a Bement collection numbering on the bottom, along with the "arrow" that the AMNH curator Gratacap used to show alignment of specimens on a display shelf. This indicates the piece was on display after the donation of the Bement collection around 1910, by JP Morgan

A most unusual specimen with a 2.5-cm brazilianite crossing the termination of a gorgeous, jewel-like quartz crystal , totally water-clear and perched in albite matrix. The quartz measures about 8 cm tall and its termination is freestanding save for the crossing brazilianite atop. VERY dramatic and unusual specimen!

BOURNONITE on QUARTZ from Herodsfoot Mine, Cornwall, England [db_pics/pics/bournonited.jpg]

This is a fine old classic but also an aesthetic, well-balanced specimen at the same time, featuring a superb bournonite crystal perched at the top of a knoll of lustrous quartz crystals! The bournonite measures 2.5 cm across and has excellent form combined with naturally bright lustre (i.e. it hasn't been chemically cleaned to make it too bright). The piece displays well from both sides and sits nicely on its own, without need of support. It is one of the best for its size of this classic association that I have seen for sale in recent years and is unusual in its superb aesthetics beyond that simple statement. Leithauser REALLY had good taste and did not just buy classics to have them...he waited until the perfect aesthetic example of a classic came along, and only then got his piece. You'll see in the collection how few duplicates he had, because he really was after the stereotypical representation of a "classic," and seldom settled for anything less than a piece that exemplified everything you would want in an important old locality piece but ALSO had the aesthetics you'd demand in a contemporary specimen. This is one such.

Topaz on Quartz from Sakangyi, Mogok, Burma [db_pics/new2012/BC16e.jpg]

This very large combo specimen is composed of a 13 cm-long colorless quartz crystal attached to a doubly-terminated, glassy and gemmy, light champagne-colored topaz measuring 7 cm in length. The asssociation is unlikely, in such size and geometry, but there you have it. The topaz is actually complete, with an old break on the bottom grown over by later deposition of topaz. The basal termination on the bottom now is "healed", and it features many individual faces.The top termination is crystallographically interesting with its sharp steep faces in which you can find pyramids, prisms and a dome shape. There is very minor and insignificant bruising on the lower right hand side of the topaz. This is a major combo specimen from Mogok that weighs 824 grams (over 2 pounds). From the Burma collection of "Burma Bill" Larson, who has for decades brought out gems and then minerals as this region opened up to the trade in specimens.

An aesthetic combo specimen features a 6 cm long ,lustrous, cream-colored microcline crystal that has two lustrous and translucent, smoky quartz crystals, to 2.7 cm in length, at the base of the feldspar. Sharp and geometric, this piece has a porcelain-like beauty to it. There is even a secondary overgrowth on the back side of the larger microcline. A tiny ding at the termination of the microcline crystal does little to detract from the specimen. From the Burma collection of "Burma Bill" Larson, who has for decades brought out gems and then minerals as this region opened up to the trade in specimens.

Erupting straight up from two glassy and gemmy, colorless quartz crystals to 4.5 cm in length, is a limpid, glassy and gemmy, colorless topaz crystal. This gem is bright and pretty - 2 inches (just over 5 cm) in length in total. The topaz is superbly centered high on its matrix. The mass is 114 grams. From the Burma collection of "Burma Bill" Larson, who has for decades brought out gems and then minerals as this region opened up to the trade in specimens.

This specimen features a dramatic 3 x 2 inch morganite hanging off the side of a smoky quartz. association pieces, and good morganite of any kind for that matter, is uncommon in San Diego except for the famous White Queen Mine (and even there, not THAT cmmon)! The morganite is complete on the front, contacted and partially recrystallized on the back. Morganite from County is usually rather etched, as well. But, not this one. A remarkable display specimen found by Roland Reed and passed on to Chuck in the 1990s.

Tourmaline, Quartz, Cleavelandite from Cryo-Genie Mine, nr. Warner Springs, Northern San Diego County, California, USA [db_pics/pics/ch02a.jpg]

This remarkable matrix specimen was collected by Ken and Dana Gochenour from the "Payday Pocket" mined just prior to October 2003. These were considered some of the better tourmalines from the mine by outsiders to collecting County tourmalines as they had a prismatic habit rather than the tapered habit typical of the Big Monday and B.A.T. Pockets this mine was better known for. Only 3 really fine matrix specimens of this style are known from the mine and this may very well be the best of them, according to Chuck. It is very well-displayed, as a combination of the pocket minerals, and is undamaged except for one clean repair done by the miners.

This is a County specimen so outstanding, so atypical, that one at first thinks it must be Afghani! It is a PURPLE CAPPED, gemmy, matrix tourmaline from the famous old Stewart Mine: Mined 6/11/88 from a pocket in the roof of the Little Joe II tunnel of the Stewart Mine. The specimen was found on the floor of the tunnel minus the top of the main quartz crystal. Week later, the miners searched the pile of rubble building up on the tunnel floor under the pocket and located the top of the quartz crystal, now repaired (fairly cleanly) back on the specimen. The tourmaline itself is NOT repaired, only the quartz termination flanking it. The tourmaline is pristine on the display face, though contacted and missing a bit on the rear-right side. However, this does not really detract visually from the specimen, although otherwise it would have been worth more I admit. The back isn't bad, other than this slight discontinuity which again, can be moved away form the display face anyhow. This is a superb display specimen and a unique County piece, with great pedigree. I have not seen another example of the purple caps from Stewart, rare as they are, on matrix and so large. One of my hands-down favorites of the collection! Chuck has added this comment to the draft: This specimen was collected prior to Blue's involvement. Lynn Agabashian was running the shop at the time and Jose was doing the mining. Also, you lowered the price to $10,500, I'd keep it at $12,000 like you had it in the appraisal, I really think it is worth it! By the way, this was the first "serious" SD Co specimen I purchased, directly from Lynn and Gems of Pala, in 1988. Man that was a lot of money!
