April - Diamond

Engagement diamonds have been worn on the third finger of the left, for Egyptians believed the "vein of love" connected this finger to heart. Until the 15th century only royalty, nobility and priests were allowed to own and wear diamonds. Since diamonds are unique, precious and invincible they represent lasting love and the symbol or pledge between two people. Diamond is from Greek word "adamas" meaning unconquerable and they are principally found in South Africa, Botswana, Zaire, Russia, Australia and Canada.

Robert M. Shipley, who found the Gemological Institute of American (GIA) in 1931, also founded the American Gem Society (AGS) in 1934. The mission of the AGS is to promote ethnics, knowledge and consumer protection. Throughout the world there are many diamond grading systems. Only the AGS and GIA systems qualify and quantity grades with specific and accurate terms detailing the grading factors for a diamond.
