![]() This liberal policy adopted by the State Authorities, had yielded rich dividends, by boosting tourist attractions to the State, and the park undoubtedly has become the State's biggest tourist attraction. Crater of Diamonds State Park, is the world's only publicly-owned diamond prospecting site, where visitors are allowed to search for diamonds and other gems, for a fee, and keep what they find, regardless of the value of the gems. The Kahn Canary diamond was discovered by a logger, George Stepp of Carthage, Arkansas, in the Crater of Diamonds State Park, near Murfreesboro, Arkansas, in 1977. History Discovery of the Kahn Canary diamond Images of two of the most famous canary yellow diamondsĢ05.07-carat canary yellow Red Cross Diamond Two of the most famous canary yellow diamonds in the world are, the 205.07-carat Red Cross diamond and the 128.54-carat Tiffany Yellow diamond. Therefore the Kahn Canary is also a rare Type I b diamond. Thus canary yellow diamonds are Type I b diamonds that constitute only 0.1 % of all naturally occurring diamonds. The rare canary yellow belongs to this group. When nitrogen atoms are scattered as single atoms in the crystal structure, they absorb visible light in the blue end of the spectrum imparting an intense yellow color to the diamonds. Only 0.1 % of natural diamonds belong to this group. Type I b :- Nitrogen atoms scattered as single atoms. 98 % of all natural diamonds belong to this group. Type I a :- Nitrogen atoms found as groups of atoms. The basis for this division is whether the nitrogen atoms are distributed as single atoms or groups of atoms in the crystal structure. Type I diamonds are sub-divided in two :- Type I a and Type I b. The remaining 1-2 % of natural diamonds that do not contain nitrogen impurities are known as Type II diamonds. Almost 98 % of all natural diamonds contain nitrogen impurities and are therefore classified as Type I diamonds. Octahedral diamond crystal - the most common crystal habit in diamondsĬubic and octahedral crystal habits of diamonds from AfricaĬubic diamond crystals from Zaire in Africaĭiamond crystals that do not conform to the cubic or isomeric crystal system Flat triangular diamond maclesĮtched trigons on the surface of diamondsĪll yellow colored diamonds are Type I diamonds, because they contain nitrogen impurities that impart the yellow color to diamonds. Images of Octahedral crystals - the most common crystal habit in diamonds Real diamond crystals don't have completely smooth faces, but may have raised or indented triangular growths called 'trigons'. These are the flat triangular form called the macle, which are actually composite crystals and etched crystals, having rounded surfaces and sometimes elongated shapes. However,there are at least two crystal habits of diamond, that do not conform to the cubic crystal system. All these shapes are manifestations of the cubic or isometric crystal system. The most common crystal habit in diamonds is the octahedron. The uniqueness of the diamond in its natural uncut form has made it the unofficial symbol of Arkansas State, nicknamed "The Natural State."ĭiamonds belong to the cubic or isometric crystal system.The basic crystal structure of diamond is a face-centered cubic lattice (FCC), which can build up into crystal habits, such as the six-sided cube, 8-sided octahedron or the 12-sided dodecahedron, or a combination of these shapes, such as cubo-octahedron. The weight of the diamond is 4.25 carats. The Kahn Canary has been preserved in its natural rough state because of its unique natural dodecahedral (12-sided) pillow shape, with its rare canary yellow color, that radiates a brightness and brilliance that equals or perhaps surpasses a cut and polished diamond. ![]() The name of the diamond combines the name of the owner with the rare intense yellow color of the diamond, known as canary yellow.Ĭharacteristics of the diamond The Kahn Canary diamond is preserved in its unique natural dodechedral pillow shape form ![]() The Kahn Canary diamond gets its name from Stan Kahn, of Kahn Jewelers in Pine Bluff, Arkansas, who purchased the unnamed diamond from its founder, George Stepp, a logger from Carthage Arkansas.
