Large Cat's-Eye AQUAMARINE.

- Abstract
The article presents information on a large cat's-eye aquamarine. The large collector-quality specimen of cat's-eye aquamarine was examined at the East Coast laboratory. The stone was cut as a high-domed oval cabochon and displayed a fairly sharp, straight eye. Chatoyancy in beryl is commonly caused by tube-like inclusions or growth tubes oriented parallel to the c-axis. The cabochon was a medium greenish blue with absorption lines in the desk-model spectroscope which are consistent with aquamarine. This stone is a very notable gemstone due to its color and well-defined chatoyancy.
