September's birthstone is the sapphire. Both Virgo and Libra born in the month of September share the sapphire as their birthstone. Named after the Greek word "sapphirus," meaning blue, the striking deep color of the sapphire is often compared to a cloudless sky. A luminous bouquet mixed with an array of deep colors reminiscent of the midnight sky is a perfect choice for September birthdays.
Ancient civilizations believed that the world was set upon an enormous sapphire, which painted the sky blue with its reflection. Sapphires have long been a favorite among royalty and scholars, who considered them symbolic of wisdom and purity. The sapphire is prominent among the British Crown Jewels, and Prince Charles chose this as the engagement stone for his fianc┬Ę┬Že, Princess Diana.
