Sapphire is generally known as a blue gemstone but surprisingly it comes in a wide range of colors and quality variations. In general, the more intense and uniform the color is, the more valuable the stone.
Sapphires that are not blue are known as fancy sapphires, and may be any colour—except red (which is a ruby). There truly is a different color of sapphire to suit anyone’s taste!
Colour has the greatest influence on a sapphire’s value. The most valued blue sapphires are velvety blue to violetish blue, in medium to medium-dark tones. Sapphires with these qualities command the highest prices per carat. Blue sapphires with extremely high clarity are rare, and very valuable.
Sapphires are rated 9 on the Mohs Hardness scale, which means it is the 2nd hardest gem next to diamonds! That is part of the reason why they are often used in engagement rings as it represents ever-lasting love and make suitable heirlooms to be passed down for generations.
Often associated with royalty, sapphire is believed to attract abundance, blessings, and gifts. It has been used to protect against negative energies, as well as calm the mind, strengthen intuition, and invite spiritual clarity. One of the most famous sapphire engagement rings belonged to the late Princess Diana and is now worn by Catherine, Duchess of Cambridge, the wife of Princess Diana's eldest son, Prince William.
