The undisputed “King of Gemstones,” the ruby has been considered one of the most valuable gemstones on earth for thousands of years. It has everything a precious gemstone should have, magnificent color, excellent hardness, and outstanding brilliance. As such, rubies can command the highest per carat price of any gemstones. Take for example the 48.019ct Mandalay Ruby, which has been estimated by Sotheby’s at $15 million in 1988. Intensely vibrant and passionately red, rubies have sparked the imagination and emotions of countless poets and lovers alike. Warm, seductive, and fiery, the ruby is not for the calm of heart, but those who live life to the fullest and love with unbridled abandon.
