August birthstone
For August, the modern birthstone is peridot, a gem that seems to hold sunlight within its green body. It lends a character of quiet warmth and steady clarity, as if you carry a piece of late-summer meadows wherever you go.
August’s stones across the traditions
History & lore
Peridot has been mined for thousands of years, with ancient sources on Zabargad Island in the Red Sea. It was prized by Egyptian pharaohs and later by medieval crusaders who brought it to Europe, often confused with emerald but distinguished by its vivid lime-green hue. Sardonyx, the traditional August stone, was used in Roman signet rings for its layered colors, while Ayurvedic tradition associates August with deep blue sapphire.
What it’s said to carry
Traditionally, peridot is said to bring peace, calm, and protection to its wearer, with lore linking it to lightening the heart and soothing resentment or envy. Sardonyx was believed to encourage courage and clear speech, and sapphire in Ayurvedic practice is associated with wisdom and spiritual insight. These are cherished cultural associations, not scientific claims.
Wearing & choosing it
When choosing peridot, look for a rich olive-green to lime color with minimal inclusions; it suits both gold and silver settings and works well as a pendant or ring. Sardonyx offers a banded red-brown and white appearance for a more classic look, while sapphire provides a cool blue contrast if you prefer a deeper tone. Each stone can be worn to honor August, depending on your taste in color and style.
