The Other August Birthstone

August is just around the corner…already… and that means the Peridot your birthstone if your birthday falls within that month. So many people have told me how they feel ripped off, even my daughter, when it comes to their birthstones. They think that it’s the ugliest of them all. I’m not here to change that argument but rather to show those August babies that Peridot is not their only choice.

Sardonyx is an interesting stone that also shares the distinction of being another birthstone of August. Sardonyx combines alternating layers of sard and onyx—two types of the layered mineral chalcedony—to create a reddish zebra-striped stone with white bands.

Its name combines sard (referencing the ancient Persian city, Sardis, in present-day Turkey, where the red stone was found) with onyx (from the Greek word of the same spelling, which meant “nail or claw.”)

Sard ranges in color from yellowish red to reddish brown, depending on how much iron oxide is present. Sard is easily confused with carnelian, another type of chalcedony that is slightly softer and lighter in color. It has rich oranges and red tones that make it perfect especially since those are the colors of the season!

Sardonyx, like onyx, shows layers of parallel bands—instead of the chaotic, curved bands that compose agate, another type of chalcedony.
Even if green is not your thing, you do have another choice!
