August Birthstone Peridot: Everything You Need to Know

Short Answer

Peridot is the primary birthstone for August, known for its vivid yellow-green to olive color. It's one of the only gems that comes in a single color, and it forms deep in the Earth's mantle rather than the crust.

It's affordable compared to most colored gems, but at 6.5 to 7 on the Mohs scale, it's softer than a ruby or sapphire. Protective settings and gentle care matter, especially in rings.

Peridot might be the most underrated gemstone in the jeweler's case. It's the green that isn't emerald, the stone that likely fooled Cleopatra's court, and one of the few gems on earth that occasionally arrives from space.

If you were born in August, or you're shopping for someone who was, there's more to this stone than a pretty color. Here's everything worth knowing about the August birthstone Peridot.

You’ll know where it comes from, what makes one worth more than another, how durable it really is, and what to check before you buy.

Where Peridot Comes From

August birthstone Peridot has one of the more remarkable origin stories in the gem world, and a few facts are worth knowing:

• It forms deep in the Earth's mantle, 30 to 90 kilometers down, and reaches the surface through volcanic activity. Diamond is the only other well-known gem that forms that deeply.

• Some peridot comes from space. It's been found inside meteorites, and those crystals are occasionally cut for collectors.

• Arizona supplies most of the world's peridot, mined on the San Carlos Apache Reservation.

• Pakistan produces the finest stones, prized for exceptional clarity and a vivid, saturated green.

• Egypt's Zabargad Island was the original ancient source, mined more than 3,000 years ago.

Why Peridot Is Only Ever Green

Peridot is what gemologists call idiochromatic, meaning its color comes from its own chemistry rather than trace impurities. Most gems get their color from tiny amounts of foreign elements. Peridot gets its green from the iron built into the stone itself.

That's why you'll never see a blue or pink peridot. The shade ranges from bright yellowish-green to deep olive, and the iron content decides where it lands. More iron means a darker green.

For value, the most prized color is a pure grass green with no yellow or brown tint. That version is the rarest and the most expensive.

Meaning and Symbolism

The ancient Egyptians called peridot the "gem of the sun" and believed it held sunlight's warmth and power. It was carried as a talisman against evil spirits and, as the old texts put it, the terrors of the night.

It's also been mistaken for emerald for centuries. Historians believe much of Cleopatra's famous emerald collection was likely peridot.

Today, peridot symbolizes renewal, protection, and good fortune. It's the traditional gemstone for a 16th wedding anniversary.

How Durable Is Peridot?

This is the honest part, and it matters most if you're buying a ring.

Peridot sits at 6.5 to 7 on the Mohs hardness scale. That's softer than sapphire and ruby (both 9), and even softer than aquamarine. Every day, dust and grit sit around a 7 themselves, which means they can scratch it over time.

It's also somewhat brittle and sensitive to acids. Over the years, even the acidity in skin oils can slowly etch the surface. Sudden temperature changes are a risk, too, since peridot is vulnerable to thermal shock.

None of this makes peridot a bad choice. It simply means it shines brightest in earrings, pendants, and occasional-wear rings rather than a ring you'll never take off. If you do want a peridot ring for regular wear, a bezel setting that wraps the stone in metal is your best protection.

What to Look for When Buying Peridot

Peridot is graded on the familiar factors, but they don't matter equally:

• Color leads. A rich, pure green with no brown or yellow cast commands the highest price. Olive and yellowish stones cost less.

• Clarity counts. Fine peridot should be eye-clean, since visible inclusions noticeably lower the value.

• Cut shapes the glow. Oval, cushion, and emerald cuts are popular for showing off peridot's brilliance.

• Size stays affordable. Larger peridots are more available than large stones in most colored gems, so a bold piece stays within reach.

• Treatment is rare. August birthstone Peridot is almost never treated or lab-grown, since the natural supply is plentiful. What you see is usually what you get.

Quality varies widely, so buy from a seller who's clear about color grade, clarity, and origin.

Caring for Your Peridot

Peridot needs a gentler touch than harder stones. A few habits keep it beautiful for decades:

• Clean it with mild dish soap, warm water, and a soft-bristle brush.

• Never use ultrasonic or steam cleaners, since peridot is vulnerable to thermal shock.

• Keep it away from acids and harsh household chemicals.

• Store it separately, so diamonds and sapphires don't scratch it.

• Take rings off before workouts, cleaning, and gardening.

August's Other Birthstones

Peridot isn't alone. August actually has three birthstones, which gives you options.

Spinel was added in 2016 and comes in nearly every color, from vivid red to pink to blue. At 8 on the Mohs scale, it's noticeably more durable than peridot, which makes it a stronger choice for an everyday ring.

Sardonyx is the oldest of the three, with banded reddish-brown and white layers and a history stretching back more than 4,000 years.

Peridot remains the stone most people picture for August, but spinel is worth considering if durability is your priority.

FAQs

What does the August birthstone peridot symbolize?

Peridot is associated with renewal, protection, and prosperity. Ancient cultures carried it as a talisman against evil spirits and nightmares, and the Egyptians linked it to the power of the sun. It's also the traditional gift for a 16th wedding anniversary.

Is peridot durable enough for an engagement ring?

It can work, but it isn't the sturdiest option. At 6.5 to 7 on the Mohs scale, peridot is softer than sapphire or ruby and can scratch or etch over time. If you love it for a ring, choose a protective bezel setting and be a little mindful about when you wear it.

Why is peridot always green?

Because its color comes from the iron in its own chemical structure, not from outside impurities. That makes peridot one of the very few gems that occur in a single color family. The amount of iron decides whether it leans bright yellow-green or deep olive.

Is peridot expensive?

Generally, no. Peridot is one of the more affordable colored gemstones, especially next to emerald or ruby, and larger stones stay reasonably priced. Fine stones with a pure, saturated green and excellent clarity do command a premium.

What's the difference between peridot and emerald?

Color and chemistry. Peridot is a brighter, more yellow-green, colored by iron, while emerald is a deeper green, colored by chromium. Emerald is also harder and far more expensive. The two have been confused for centuries, including in Cleopatra's collection.

Can peridot be lab-grown?

Rarely. Because natural peridot is relatively abundant and affordable, there's little commercial reason to grow it in a lab. Nearly all peridot on the market is natural and untreated, which is part of its appeal.
