Throughout history, sapphires have always been associated with the color blue, perhaps most likely due to their name, which comes from the Greek word sappheiros (blue stone). Traditionally, sapphire symbolizes truth, sincerity, and faithfulness. In history, clergy members wore the gem to symbolize Heaven. In ancient Greece and Rome, the royals believed sapphires protected them from envy and harm. Sapphires have also been closely associated with romance and the royals, most recently in modern times. In 1981, Prince Charles gave Lady Diana Spencer a blue sapphire engagement ring. The same ring was later given to Kate Middleton by Prince William
But all sapphires are not blue and, in fact, come in a rainbow of colors including varying shades of blue as well as “fancy sapphires” in pink, yellow, orange, lavender, purple. Blues can be pure blue but may have a range from greenish blue to violet blue. The blue in a sapphire is the result of trace elements of iron and titanium; the more iron in the sapphire, the darker the blue.
