Throughout history, sapphires have been associated with the color blue. Its name is derived from the Greek word sappheiros; which probably referred to lapis lazuli. Indeed, sapphires can be found in a range of blue hues. The celestial blue color of this gem symbolizes heaven, loyalty and integrity. In ancient Greece and Rome, kings and queens believed blue sapphires protected them from envy and harm. The ancient Persians believed the earth rested on a giant sapphire, and the reflection made the sky blue.

In ancient times, a gift of a sapphire was a pledge of trust and loyalty. It is from this tradition that sapphire has long been a popular choice for engagement rings. In 1981, England’s Prince Charles gave Lady Diana a 12-carat blue sapphire engagement ring. Almost 30 years later, Prince William gave this ring to Kate Middleton.

However, sapphires come in an array of colors: pinks, yellows, greens, oranges and violets- which are often referred to as fancy sapphires. Sapphires come in every color except red. If a sapphire is red, it is classified as a ruby; both are part of the corundum mineral family.

Sapphires are assessed by color, clarity, cut, and carat size, just like diamonds. The origin of the sapphire like other colored gemstones can also determine the price.

Color is the key indicator of price. The highest valued sapphires are vivid blue, sometimes with a violet hue.
