The August birthstone is one of the most fascinating in the birthstone calendar because August is represented by three official gemstones: peridot, spinel, and sardonyx. While many people immediately associate August with the vibrant green glow of peridot, the addition of spinel to the modern birthstone list and the centuries-old tradition of sardonyx give August-born individuals an exceptional variety of gemstones to choose from.
Each August birthstone offers unique beauty, symbolism, history, and meaning. Whether you're searching for a meaningful birthday gift, curious about gemstone symbolism, or interested in astrology, jewelry, or crystal traditions, this comprehensive guide covers everything you need to know.
What Is the August Birthstone?
Unlike most months, August has three recognized birthstones:
- Peridot (modern primary birthstone)
- Spinel (modern alternative birthstone)
- Sardonyx (traditional birthstone)
Peridot has represented August since the standardized modern birthstone list was introduced in the early 20th century. Sardonyx has been connected with August for centuries, while spinel officially joined the list in 2016, providing another beautiful option for August birthdays.
This trio gives August one of the broadest color palettes of any birth month, ranging from brilliant lime green to vivid reds, pinks, blues, blacks, browns, and striking banded patterns.
Why Does August Have Three Birthstones?
Birthstone traditions have evolved over thousands of years.
Originally, each month was assigned a single gemstone based on historical customs, religious symbolism, and availability.
As gemstone discoveries increased and jewelry preferences changed, official organizations expanded several birthstone lists to offer:
- More affordable choices
- Better gemstone availability
- Greater variety of colors
- Different durability options
- Modern jewelry trends
This explains why August now includes three distinct gemstones rather than one.
Peridot: The Primary August Birthstone
Peridot is the gemstone most people think of when discussing the August birthstone.
Its unmistakable green color has earned it recognition around the world for thousands of years.
Peridot Color
Unlike many gemstones that occur in multiple colors, peridot naturally appears only in shades of green.
Common hues include:
- Yellow-green
- Olive green
- Lime green
- Golden green
- Deep grassy green
Its color comes from iron within the crystal itself rather than impurities.
The richer the green and the fewer brown tones present, the more valuable the gemstone generally becomes.
Peridot Meaning
Throughout history, peridot has symbolized:
- Happiness
- Good fortune
- Prosperity
- Renewal
- Growth
- Positive energy
- Inner peace
- Confidence
Many cultures believed it protected the wearer from darkness, nightmares, and negative influences.
Today it remains associated with optimism and emotional balance.
Peridot History
Peridot has one of the oldest documented gemstone histories.
Ancient Egyptians mined it on an island in the Red Sea over 3,000 years ago and called it the "Gem of the Sun."
Many historians believe several gemstones once identified as emeralds—including some in famous royal collections—may actually have been peridot.
The stone later became popular across Greece, Rome, medieval Europe, and Asia.
Where Is Peridot Found?
Major sources include:
- United States (Arizona)
- Pakistan
- Myanmar
- China
- Vietnam
- Tanzania
- Egypt
Rare peridot has also been discovered inside meteorites, making it one of the few gemstones known to originate beyond Earth.
Peridot Hardness
- Mohs hardness: 6.5–7
This makes peridot suitable for most jewelry but slightly softer than sapphires, rubies, or diamonds.
Extra care helps prevent scratches.
Spinel: The Modern August Birthstone
Spinel became an official August birthstone relatively recently, but its history stretches back centuries.
For hundreds of years, spinel was mistaken for ruby because of its remarkable brilliance.
Several famous "rubies" in royal crowns are actually red spinels.
Spinel Colors
Spinel is one of the most colorful gemstones available.
It naturally occurs in:
- Red
- Pink
- Orange
- Purple

Spinel Meaning
Spinel is commonly associated with:
- Inspiration
- Vitality
- Hope
- Courage

- Emotional renewal
- Resilience
Many crystal enthusiasts believe spinel encourages fresh beginnings after periods of stress.
Why Spinel Is Special
Spinel offers several advantages:
- Excellent brilliance
- High durability
- Wide range of colors
- Often better value than ruby
- Excellent everyday wearability
With a Mohs hardness of 8, spinel is considerably more durable than peridot.
Sardonyx: The Traditional August Birthstone
Before peridot became widely recognized, sardonyx represented August for generations.
Its distinctive layered appearance makes it instantly recognizable.

Each gemstone is completely unique.
