Since diamonds are unique, precious and invincible they represent lasting love and the symbol or pledge between two people. Diamonds have been worn on the third finger of the left hand, for the Egyptians believed the " vein of love" connected this finger to the heart. Until the 15th century, diamonds were worn only by royalty, nobility and priests. The first diamond engagement ring was given in 1477 by Archduke Maximilian of Austria to Mary of Burgundy. The wedding took place 24 hours later. In these times diamonds were uncut, so they were valued as a symbol of strength and protection, not beauty.

It was not until the 20th century that the possibility of owning a diamond came within the reach of the American public. By the end of World War II, the tradition of the diamond engagement ring was firmly established in England and the United States as a symbol of love and commitment. Today, some nine out of ten brides receive a diamond engagement ring.
