Diamond from Crater of Diamonds State Park (Arkansas Diamond Corp. Mine; Mauney Mine; Ozark Mine; Prairie Creek Lamproite), Murfreesboro, Pike Co., Arkansas, USA [db_pics/mdpics/MD-39515a.jpg]

This specimen is a very fine, somewhat rounded dodecahedron of gem-quality. The color is a rich honey-brown, attractive and unusual for the locality. The diamond weighs in at an impressive 1.28 cts. Dedicated miners may search months or even years for a diamond of this size and quality! Found only this past August, it comes in a display box with a registration card and one of the new AR quarters showing a diamond as one of the state's symbols. 1.28 cts : 5 x 4 x 3 mm

A super, lustrous, gemmy 1.80 ct transparent and mostly clean, unusually colored diamond from Crater of Diamonds, AR -- found by Sean Allen w/ Park card. It has a darker area at one end, but is more attractive and this less noticeable in person. A very nice-sized, displayable specimen. 1.8 cts : 9 x 5 x 2 mm

An interesting, window-clear, flattenned octohedron that came in with the macles because it look sflattish, but actually really is a weird octohedral variant 0.79 carats: 7 x 6 x 1 mm

Diamond from South Africa [db_pics/mdpics/MD-39519a.jpg]

This macle twin is not only stunning, but is also rather thick at 3.5 mm in thickness to have such clarity. It is very clean throughout, with only a few extremely slight carbon inclusions , and you could call it gemmy and literally mean "GEMMY" when you say it. . It has an amazing PRESENCE and is just astonishing to hold in your hand...you really have trouble believing that this is a REAL diamond! The triangular form is unusually equant for a stone of this size, and it "looks" naturally cut. It has, obviously, considerable gem rough value and I am told it should yield about 40% recovery in the form of several large stones and some smaller ones. Bottom Line: this is one of the largest and finest specimen diamonds I have seen for sale on our market, to survive the butchers...er, cutters. It certainly is the biggest diamond of any quality that I have seen for sale on the open market as a specimen in 2 years or so since i last had one of these beasts. In person, it presents as simply an astonishing piece to both collectors and layment alike. MORE CLEAR IN PERSON! 9.94 carats: 1.6 x 1.5 x 0.35 cm

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! 3.28 carats, 1.2 x 1.2 x 0.15 cm

A large, sharp, equant, translucent, yellow, spinel-twinned or macle twinned diamond from Ghana. A couple of inclusions add character to this thick, lustrous crystal. Super macle twinned diamond, for the collector! 0.9 x 0.8 x 0.4 cm

Quartz (Var: Herkimer Diamond) from Middleville, Town of Newport, Herkimer Co., New York, USA [db_pics/mdpics/MD-43238a.jpg]

A SUPERB and AESTHETIC cluster of diamond-like Herkimer quartz crystals from New York. The doubly terminated quartz crystals are extremely glassy and gemmy and the trivial termination bruising is barely noticeable. Very few of these are coming out today, due to mining restrictions. 7.3 x 7.0 x 5.0 cm

These are some of the most well-known Quartz specimens in the world. This is a very attractive little group consisting of several gemmy, sharp, highly lustrous, bipyramidal, doubly-terminated "stubby" crystals. There is little damage around the specimen and the gemminess of crystals this size is impressive. 4.8 x 4.8 x 4.3cm

Excellent, and very large, Diamond with terrific luster and a deep transluscent yellow color. It appears to have a tetrahexahedron habit or is perhaps a twinning of intergrown modified octohedra - i am not sure which ?! It is certainly sharply defined and showing an unusual number of faces. Anyways, it is big, pretty, and I think priced cheaply too.

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.
