Definitions for: Alluvial Stone.........................Bezel

Alluvial Stone - A stone that has been deposited in a sea, lake or stream bed. Diamonds and other gems are transported by water and can be found in alluvial deposits.

American Cut – Marcel Tolkowsky mathematically calculated the ideal proportions and facet angles to produce maximum brilliancy. These measurements, with a high degree of fire, in a round diamond brilliant are considered by many to be the perfect cut. The following figures are measured as a percentage of the girdle diameter: total depth, 59.3% (without provision for girdle thickness); crown depth, 16.2%; pavilion depth, 43.1%. The bezel angle is 34° 30’ and the pavilion angle is 40° 45’. Girdle thickness as a percentage of the girdle’s diameter varies with size. A larger stone will have a smaller percentage for a medium girdle. The variation is from about 1% to 3%.

Baguette – A type of diamond cut. Also a style of “step-cutting” rectangular, trapeze-shaped or small stones. From the French word meaning “rod.”

Bearded Girdle – Numerous hairline fractures extending a short distance into the stone can result from the diamond being rounded up too quickly in the fashioning process. The surface of the girdle will not appear smooth and lustrous as a finely turned girdle would. One with this appearance is seen as being “bearded” or “fuzzy.”

Bezel – Refers to three specific and related parts of the stone: The crown or proportion of a brilliant-cut gemstone above the girdle; the sloping surface between the girdle and the table; or only a small part of the sloping surface just above the girdle, which is the so-called “setting edge.”
