Blue Sapphire is one of the most popular colored stones. More consumers buy jewelry adorned with blue sapphire & than with any colored stone, especially in the U.S.
The name “sapphire” comes from the Latin sapphirus and Greek sappheiros meaning “blue stone,” though those words may have originally referred to lapis lazuli.
A rare and valuable pinkish-orange sapphire named from the Sinhalese for lotus blossom.
Sapphire is a member of the mineral species corundum, which comes in virtually every color of the rainbow. The word “Sapphire” when used alone, typically refers to the blue variety. Other colors, such as yellow, orange, Padparadscha, pink & purple are termed “Fancy Sapphire”.
Sapphire has been associated with Royalty and Romance. In ancient Greece and Rome, Kings and Queens were convinced that blue sapphires protected owners from envy & harm, make peace between enemies, influence spirits, and reveal the secrets of oracles.
