Padparadscha Sapphire

saf-ahyuh r

While sapphires have mesmerized gem and jewelry connoisseurs since the dawn of time, one fancy sapphire variety has a distinct allure and prestige all its own the mysterious and coveted padparadscha sapphire. The padparadscha derives its name from the Sanskrit "padma ranga" meaning "lotus color," for its resemblance to the beautiful and famed lotus flowers of Sri Lanka, where the gem was originally found. Padparadscha sapphires traditionally must combine elements of pink and orange in one gem to rightly claim their padparadscha title, though the coloration requirements are highly disputed.
