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
