August Birthstones

August is one of three birth months represented by three different gemstones.

In 2016, August joined June and December as one of the three birth months represented by three different gemstones. The original birthstone for August was sardonyx, and then peridot was added, becoming August's primary gemstone. The addition of spinel, which can be found in a variety of colors, gives August babies a plethora of options! Learn more about August's diverse birthstones by exploring below.



Though peridot is widely recognized by its brilliant lime green glow, the origin of this gemstone’s name is unclear.



Sardonyx combines alternating layers of sard and onyx—two types of the layered mineral chalcedony—to create a reddish zebra-striped gemstone with white bands.



The spinel is often assumed to be other gemstones because it tends to resemble either a ruby or sapphire. In fact, some of the most famous rubies in history have turned out to be spinel.
