So whether you’re into beautiful peridot jewelry, obsessed with the fiery sparkle of spinel birthstone, or drawn to the deep layers of sardonyx are the three birthstones, we’re diving into everything you need to know about August’s birthstones—history, care, style, and why they make the perfect gift for anyone born in the month of August.
The History Behind August Birthstones
Peridot: The Sun Gem of Ancient Times
The source of this august birthstone is as mystical as it gets. Peridot from Zabargad, an island in the Red Sea, was so adored by Egyptian pharaohs that they believed it could ward off "terrors of the night". This birthstone jewelry was often set in karat gold, its hue glowing in candlelight.
- Actually produced peridot: Egypt was one of the first civilizations to mine gem-quality peridot.
- Owned by a succession of rulers, peridot birthstone adorned crowns and sacred temples.
- Even today, peridot beach sand in Hawaii contains tiny crystals of this august birthstone, naturally formed from lava flows.
Spinel: The Gemstone That Fooled Kings
For centuries, spinel birthstone information was… kind of a mess. Spinel is found in Sri Lanka, Myanmar, and Afghanistan, but for the longest time, people mistook it for ruby.
- The most historic red spinel is set in Great Britain’s State Crown, known as the Black Prince’s Ruby (spoiler: not a ruby).
- Spinel is set in great royal treasures worldwide, thanks to its wealth of colors and brilliance.
- Many moorish and Spanish kings adored pink spinel as much as they loved actual ruby.
So, if you love a gemstone with drama, intrigue, and a little identity crisis, spinel birthstone is for you.
Sardonyx: The Warrior’s Birthstone
Before sardonyx was believed to be an elegant statement piece, it was a gem for August that warriors wore in battle. Carved into cameos and signet rings, this original august birthstone was a symbol of strength, courage, and protection.
- Composed of sard and onyx, the alternating bands of color give it a uniquely bold aesthetic.
- Spanish kings before Edward III prized it for its earthy, noble look.
- Ancient Romans thought wearing sardonyx birthstone meant you’d win any argument (now that’s a power move).
Mohs Scale of Hardness: Can Your August Birthstone Survive Daily Life?
