The sole birthstone for July, ruby is the brightest and boldest of all birthstones. Called ratnaraj, meaning the "King of Gems" by ancient Hindus, ruby's association with the blood of life has earned it powerful praise and high esteem since antiquity. Ruby is mentioned at least four times in the Bible, always in reference to beauty and wisdom. Its passionate red color makes ruby an ideal choice for a romantic gift that comes with a rich legacy.
