The August Birthstone: A Complete Guide to Peridot, Its Meaning, and How to Wear It

August is the long, golden stretch of the year — the month of late-summer light, warm stone underfoot, and evenings that refuse to end. It is fitting that its birthstone is a gem that looks like it was cut from sunlight itself.

If you were born in August, this is your guide: what Peridot means, why it became August's stone, how to wear it, how to care for it, and where its older sibling Sardonyx fits in. And, as always, which pieces from Sofia's studio might feel most yours.

What is the August birthstone?

The modern August birthstone is Peridot — the bright, lime-to-olive green gem that has been called the gem of the sun since antiquity. This is the answer most jewelers and friends mean when they ask about an August birthday.

August also carries an older, traditional stone: Sardonyx, a banded stone of protection worn for thousands of years. Many August lists honor both — the sunlit green of Peridot and the grounding earth-bands of Sardonyx.

The story of Peridot

Peridot is gem-quality olivine — a magnesium iron silicate born deep in the Earth's mantle and carried up to the surface by volcanoes. It is one of only two gems (with Diamond) that form not in the crust but far below it. A rare few Peridots have even arrived from space, found inside pallasite meteorites.

The Ancient Egyptians mined Peridot on Zabargad (St. John's Island) in the Red Sea and called it the gem of the sun, believing it protected its wearer from the terrors of the night. For centuries Peridot was confused with Emerald — some historians believe several of Cleopatra's famed emeralds were, in fact, Peridot.

Because Peridot forms as a single, idiochromatic green — it is green all the way through, never dyed or tinted — every stone glows with the same warm olive light. Our Peridot beads are natural and ethically sourced, with the soft lime-green transparency the stone is loved for.

What Peridot means

Peridot is traditionally the stone of light, warmth, and renewal. It is the crystal people reach for to lift a heavy mood, invite abundance, and let a little sunlight back in.

• Chakra: Heart and Solar Plexus — green for the heart, gold-green for personal power.
• Element: Earth and Fire.
• Zodiac: Leo (July 23 – August 22) and Virgo.
• Anniversary: The 16th wedding anniversary.

People traditionally wear Peridot to:

• Lift low moods and invite lightness and optimism
• Open the Heart chakra to warmth and abundance
• Release old resentment, jealousy, or stuck energy
• Carry a piece of summer sun through the darker months

None of this is a medical claim. It is what people have quietly written down about Peridot for centuries.

Peridot in jewelry — what to look for

Peridot scores 6.5 to 7 on the Mohs scale — well-suited to everyday wear, though a touch softer than Quartz, so it deserves a little care.

• Color: The most prized Peridot is a pure grass-green; slightly yellow or olive tones are equally natural and beautiful. There is no brown in a fine Peridot.
• Clarity: Good Peridot is clean and glassy. Its high double refraction gives it a soft, velvety glow rather than a hard sparkle.
• Cut: Faceted beads catch the green light beautifully; tumbled Peridot reads softer and more elemental.

How to wear Peridot every day

• Layered with gold: Warm-yellow gold and green Peridot is one of the great summer pairings — it reads sunlit and rich.
• Layered with silver: Cooler and more modern; silver makes Peridot's green look crisp and fresh.
• Against summer wardrobes: Peridot glows against white linen, denim, and every warm earth tone.
• Alone on the wrist: A single Peridot bracelet is a quiet dose of daylight — you do not need much to feel it.

How to care for Peridot jewelry

1. Cleaning: Warm water, mild soap, a soft cloth. Avoid ultrasonic cleaners — Peridot can be sensitive to sharp vibration.
2. Avoid acids and heat: Peridot dislikes sudden temperature changes and acidic cleaners. Keep it away from harsh chemicals.
3. Storage: In its own pouch. Harder stones like Quartz or Ruby can scratch it, so store it separately.
4. Cleansing (energetic): Moonlight, running water, or a night on a piece of Selenite. Peridot's sunny energy also loves a little morning sunlight.

Sardonyx — August's traditional guardian

Long before Peridot topped the August list, there was Sardonyx — a banded stone of reddish-brown and creamy white, a member of the chalcedony family. Roman soldiers carried Sardonyx carved with figures of heroes, believing it lent them courage in battle; because hot wax would not stick to it, it became the favorite stone for signet rings and seals.

Sardonyx is the grounding counterweight to Peridot's light: a stone of strength, protection, and steady willpower, tied to the Root chakra. If Peridot is the summer sun, Sardonyx is the warm earth it shines on. Together they make a beautiful August pairing — lightness held by ground.

Frequently asked questions

Is Peridot a good birthstone gift?

Yes — Peridot is the modern August birthstone and also the gem of the 16th wedding anniversary. Its bright, cheerful green makes it a lovely birthday or milestone gift.

What color is Peridot?

Peridot is always green — ranging from a pure grass-green to a warm yellow-green or olive. It is green all the way through, never dyed. If a stone shows brown, it is a lesser-quality Peridot.

Can Peridot be worn every day?

Yes, with a little care. At Mohs 6.5 to 7 it is suited to daily wear, but it is softer than Quartz — keep it from hard knocks, harsh chemicals, and ultrasonic cleaners.

What is Peridot's meaning spiritually?

Peridot is traditionally the stone of light, warmth, and renewal — worn to lift the mood, open the heart, release old resentment, and invite abundance. The Egyptians called it the gem of the sun.

What is the difference between Peridot and Sardonyx?

Both are August stones. Peridot is the modern birthstone — a bright green gem of light and renewal. Sardonyx is the older, traditional stone — a banded brown-and-white stone of protection and strength. Many people wear both.

Why is Peridot the August birthstone?

The modern birthstone list was formalized by the American National Retail Jewelers Association (now the American Gem Society) in 1912, which assigned Peridot to August. Its association with the sun and with late-summer light stretches back to Ancient Egypt.

Every piece is wire-wrapped by hand at Sofia's studio, cleansed under the full moon, and packed in a hand-stamped pouch. If August is your month — or if you are just drawn to the green — we hope this guide helps you find the right piece.
