Rubies, the birthstone for July and the traditional gem for 40th wedding anniversaries, are among the most prized and enduring gemstones in history.

A variety of the mineral corundum, rubies owe their rich red color to the presence of chromium, and their vibrant hue ranges from pinkish-red to deep crimson.

Historically favorited by royalty and nobility, rubies have been sourced from countries such as Myanmar (formerly Burma), Thailand, Sri Lanka, and more recently, Mozambique.
