A 9.39 carat Cat’s Eye Chrysoberyl is the Star of this Vintage Style Ring.
Cat’s eye has the longest history of gems in the chrysoberyl family. It was treasured in Asia before the birth of Christ and became quite well known in Rome by the end of the First Century. In the symbolic necklace of Vishnu, a green cat’s-eye chrysoberyl represented the magnetic center of human passion. The popularity of Cat’s Eyes sky-rocked in the 19th Century after the Duke of Connaught presented his fiance with a cat’s eye betrothal ring. Ceylon, where most of the examples of cat’s eye were mined could not keep up with the overwhelming demand.
Sri Lanka and Brazil hold the main deposits of fine quality, transparent greenish yellow, chrysoberyl which were very popular in Victorian and Edwardian Europe.
When traders speak about “cat’s-eye” without a postfix, cymophane is implied and this gemstone has the longest history of the chrysoberyls. It was treasured during Biblical times in Asia and in a Vishu necklace a cymophane was the representation of the magnetic center of human passion. During Victorian times the popularity of cymophane reach its peak after Prince Arthur, Duke of Connaught and Strathearn and 3rd son of Queen Victoria, gave his future wife – Princess Louise Margaret of Prussia – a betrothal ring set with a chrysoberyl cat’s-eye in 1860.1
Metaphysically speaking, chrysoberyl has been attributed with the power to foster meditation and to balance one’s energy. It has long been believed to improve eyesight and to protect against evil. It was also thought to induce better relations with neighbors and Arabs believed it could make one invisible on the battlefield.
As a wedding gift, cymophane symbolizes the 18th anniversary.
