Ace of Diamonds Mine, Middleville, Herkimer County, New York, USA
Small Cabinet, 9.0 x 8.5 x 3.3 cm
This is a particularly aesthetic cluster of herk's, with real elegance to it instead of the "jumbliness" we so often get in larger chain clusters of these gem crystals. For that matter, the piece has crystals of a uniform gemminess and clarity , not marred by the usual ugly duckling in the midst of most clusters of several crystals or more. Taken together, these qualities make it a very special piece. Ed loved these, and had over 15 examples in the collection, more than any other variety of quartz. All, like this one, were carefully chosen by somebody who's seen literally hundreds over the years, to be extra special. I should say that, as with generally ALL large herkimer clusters, this piece is multiply repaired (by the collectors, usually). Comes with custom base.

A superb, equant, incredibly sharp diamond crystal that looks naturally cut due to the rare macle-twinning. Rare in such size, in specimens! I have not been able to obtain a large macle like this in 2 years or so and the availability of raw uncut diamonds of such size is seemingly going down due to changes of price and infrastructure in the diamond market. MORE CLEAR IN PERSON!

Diamonds occur in virtually every color of the rainbow (including black) and are prized for the extreme durability and fire. This particular stone has a light honey color and is only very slightly included with a Triangle cut. The color in this gem is natural, which is rare in most colorled Diamonds. It would fit nicely into a faceted Diamond suite.

Diamonds occur in virtually every color of the rainbow (including black) and are prized for the extreme durability and fire. This particular stone has a strong yellow color and is only very slightly included with a Rectangle cut. I cannot say for certain if the color is natural, but it is certainly vibrant for the species. It would fit nicely into a faceted Diamond suite.

Diamonds occur in virtually every color of the rainbow (including black) and are prized for the extreme durability and fire. This particular stone has a honey color (with a golden overtone) and is only very very slightly included with a "Round" cut. The color in this gem is natural, which is rare in most colored Diamonds. It would fit nicely into a faceted Diamond suite.
Diamantina, Jequitinhonha valley, Minas Gerais, Brazil

This is a literally spherical diamond, 11.23 carats in size and just a hair over 1 cm in diameter. It would be considered relatively large for its style, called "ballas" in diamond classification. Although round, it is not rounded by erosive forces and occurred like this naturally. According to Wikipedia's article on diamonds, at http://en.wikipedia.org/wiki/Material_properties_of_diamond : "Some diamonds found in Brazil and the Democratic Republic of the Congo are polycrystalline and occur as opaque, darkly colored, spherical, radial masses of tiny crystals; these are known as ballas and are important to industry as they lack the cleavage planes of single-crystal diamond." This is a perfect example, and is very translucent and attractive as well. It has a pleasing slight beige tint to the color - most are more gray in tone. From an old collection, and then recently in the Jim Houran collection of gem thumbnail crystals for a few years. Joe Budd Photos

This old set of various diamonds has a really fascinating mix of 11 stones that are all complete crystals of different habits. We think it was put together over 50 years ago, from the box style (Riker Mount) and old label on the back. Included here are sharp octohedrons, dodecahedrons, a triangular macle twin, and several other twin habits including the extremely rare "star of david" twins. It would cost me more than the cost of this set, to reassemble it at today's prices on good diamond crystals! . Joe Budd Photos.
