The September birthstone is the sapphire. Sapphires are most well known for being blue, but in fact, they can come in any color. Any sapphire hue is appropriate for this month's birthstone, with the exceptions of white (which is used for April) and red (which is known as ruby, and use for July). Pink sapphire and yellow sapphire are growing in popularity, but most are still blue. As a birthstone, it's said to protect you and your loved ones from harm, and is supposed to help you relax and clear your thoughts.
Birthstones are gems and other minerals that are associated with a month. This is a tradition that dates back to Biblical times, and through history it was customary to wear the stone associated with the current month during that time, then switch to the next birthstone during the next month. In addition, this was before stones could be identified as precisely as they can be today, so the identities of some of the original stones are unknown. It's only in the last century that the current list has been standard, and since then, it has been more appropriate to wear your birthstone all year 'round.
