Description

YELLOW DIAMOND CRYSTAL
Kimberley Mining District, South Africa
Diamonds have an extremely rigid lattice structure, so they can only be colored by chemical impurities and/or structural defects. Nitrogen will color Diamonds yellow, while traces of Boron will color them blue. All other Diamond colors are caused by lattice defects: structural anomalies caused by deformation during crystal growth or exposure to varying levels of radiation. This Diamond crystal is a light yellow; indicating that it is a Type Ia. When Nitrogen replaces an occasional carbon atom in the structure, then that Nitrogen is dispersed throughout the stone, can cause the blue component of daylight to be adsorbed, resulting in a Type Ia crystal that transmits and appears - yellow. This small, gemmy yellow diamond crystal weighs 1.09 carats and overall measures 6 mm from point to point and 4.5 mm on each side.
