Emerald
The natural green color of an Emerald is unmistakable. The stone represents success and is a perfect token of love and respect. Giving an Emerald makes it abundantly clear how much you care. Considered to be one of the most expensive jewels available, Emeralds have been a part of popular culture for thousands of years, beginning primarily with the Egyptians. The green variety of the mineral beryl, Emerald, gets its color from traces of chromium and sometimes iron. Emerald is designated as the May birthstone and is often given for the 20th or 35th wedding anniversaries. The finest Emeralds come from Columbia but other sources include Brazil, India and Australia
