What is Peridot? The Ultimate Guide to Peridot
In the world of gemstones, there is one that radiates a warm, sun-like green glow — both naturally vibrant and rich with ancient legends — this is peridot. Peridot is the birthstone for August and the 16th anniversary gemstone. Named for its unique olive-green hue, it’s affectionately known in the jewelry world as the "Evening Emerald" and cherished by gem lovers worldwide.
This guide will take you through everything you need to know about peridotstone —its characteristics, history, symbolism, and how to choose high-quality peridot jewelry.
What is Peridot?
Peridot is a natural mineral belonging to the Olivine Group, primarily composed of magnesium iron silicate ((Mg, Fe)₂SiO₄). Unlike many other gems, inclusions are very common in peridot stone, which is actually one of its distinctive features. One special type of inclusion is called the “water lily” inclusion, formed by a combination of internal inclusions and stress fractures. In gemology, peridot specifically refers to gem-quality olivine minerals, whose distinct green color makes them stand out among precious stones.
Other Physical Properties
- Mohs Hardness: Mohs scale rating between 6.5 and 7, sitting between quartz and topaz, giving it good scratch resistance — ideal for all kinds of jewelry.
- Specific Gravity: Ranges from 3.27 to 4.37. It feels heavier than other gemstones of similar size because of its iron and magnesium content.
- Luster: Exhibits a glassy to greasy sheen, and when polished, it shines with a captivating brilliance.
- Transparency: Varies from transparent to semi-transparent. High-quality gem-grade peridot stone generally has excellent clarity.
- Refractive Index: Between 1.650 and 1.703, with strong double refraction. This means that light passing through the stone splits into two rays — an important feature for verifying genuine peridot.
- Crystal System: Orthorhombic, with crystals typically forming short columnar or tabular shapes.
- Cleavage: Moderate cleavage, requiring extra care during cutting and setting.
Peridot’s warm glow and timeless beauty make it a gem that carries both natural vitality and a story that spans centuries.
How Does Peridot Form?
The formation of peridot is a complex and fascinating process that requires extremely high temperatures, typically occurring deep within the Earth's mantle or during volcanic activity. Most peridot stones forms in the Earth's upper mantle, where magnesium- and iron-rich magma cools and crystallizes, causing peridot stones to be one of the first minerals to crystallize. This usually happens in ultramafic and mafic igneous rocks like peridotite and basalt, which are major components of the Earth's mantle, making peridot stones an important mineral for studying the planet’s interior environment.
Additionally, peridot stones can also form in high-temperature, high-pressure metamorphic conditions when magnesium-rich carbonate rocks transform. This type of peridot stone is commonly found in contact metamorphic zones.
Surprisingly, peridot stone is not only found on Earth. It has also been discovered in comet dust and pallasite meteorites, making it one of the few gemstones with "cosmic relatives". This extraterrestrial peridot is known as “Meteorite Peridot” and carries a mysterious charm and special collectible value.
What Color is Peridot?
Peridot’s color spectrum is almost entirely within the green shades, mainly ranging from light yellow-green and olive green to brownish green.
- Yellow-green: The most common peridot color, resembling the fresh, lively tones of spring leaves — bright and full of vitality.
- Pure green: A rarer shade, showing a deep green without yellow hues. Peridot of this color is more valuable.
- Brownish green: Peridot with higher iron content takes this color, which is less popular than yellow-green peridot stone but still has a unique charm.
- Golden green: One of the most precious peridot colors, blending golden yellow and green perfectly, flashing a metallic shine in the light.
The depth of peridot's color mainly depends on its iron content: the more iron it contains, the darker the color. The highest-quality peridot gemstone should have a richly saturated, pure green tone without too much yellow or brownish tint.

Peridot's Role in Modern Science
Peridot is not only a gemstone but also an key mineral for studying volcanic activity and Earth's physical properties in modern geology. Since it exists within the Earth's mantle, peridot helps scientists understand the Earth's internal temperature, pressure, and mineral changes, providing data for earthquake prediction and mineral exploration. Variations in its composition also reflect the material cycling between the crust and mantle, offering insights into Earth's evolutionary history and plate tectonics.
Peridot also plays an important role in meteorite research. Many meteorites contain peridot, and by analyzing these space-borne gems, scientists can learn about the early conditions of the solar system. Some rare meteorite peridots have even been made into jewelry, becoming true "space gems".
Where is Peridot Found?
Peridot occurs all over the world, but its quality and characteristics vary.
- Egypt: Although production on St. John’s Island in Egypt has significantly declined, the peridot found here is considered some of the finest in the world. The peridot gems from this location are known for their pure color and high clarity.
- Myanmar: Myanmar is a key modern source of peridot, especially the Mogaung area, which is famous for its unique golden-green hue. Though the output is limited, the quality is exceptional, making them highly valuable.
- Pakistan: Kashmir in Pakistan is another important source of high-quality peridot. The gems here are generally larger, have pure color, and high transparency, making them well-suited for large jewelry pieces.
- United States: Arizona and Hawaii both produce peridot stones. Arizona's San Carlos Reservation is one of the world's most important sources, known for peridot with a slightly yellowish tint and excellent quality — primarily commercial-grade stones. Hawaii's peridot, on the other hand, has a unique volcanic origin and tends to be darker in color.
- China: Peridot can also be found in China's Hebei, Jilin, and Xinjiang regions. However, due to over-mining and current environmental protection policies, extraction is restricted. As a result, the peridot gemstones available on the market today mostly comes from North Korea.

How to Choose Peridot Jewelry?
Before purchasing peridot jewelry, it's important to understand how to assess the quality of peridot gemstones, the peridot price trends, how peridot differs from other green gemstones, and the significance of certification. This knowledge will help you find the peridot jewelry that truly delights you.
How to Evaluate Peridot Quality?
When judging peridot quality, consider four main factors: color, clarity, cut, and weight.
- Color is the most crucial element. High-quality peridot gemstones should showcase a pure green with minimal yellow or brown tones. The most desirable peridot colors range from medium to deep green with high saturation and even color distribution.
- For clarity, peridots often contain characteristic inclusions, such as lily pad-shaped patterns or black spinel crystals. While flawless peridots are extremely rare, good stones keep inclusions minimal so they don't detract from beauty. Visible cracks or large inclusions reduce the gemstone's value significantly.
- Cut greatly affects how attractive the peridot gemstones looks. Because peridot is relatively soft, cutters must work carefully. Common shapes include oval, round, emerald, and pear. A skillful cut maximizes sparkle while maintaining good proportions and symmetry.
- Weight is measured in carats. Although large peridot gemstones are more common than some gems, quality stones over 10 carats remain rare and precious. Generally, peridot gems that weigh 3 to 5 carats are the most popular on the market, offering strong visual impact at reasonable prices.
How Much is Peridot Worth?
Peridot is generally considered an affordable gemstone, and prices can range from $50 to $800 per carat. However, there are several factors influence peridot prices, like color, clarity, carat weight, cut, origin source, and market trends.
- Color impact: Color is the top factor determining peridot's value. Pure green or golden-green peridot gemstones fetch the highest prices, with quality 1-carat stones ranging from $300 to $800 per carat. Yellow-green peridot gemstones are moderately priced, usually between $50 and $300 per carat. Peridots with brownish hues tend to be lower in price.
- Clarity grade: Flawless peridot gemstones are exceptionally rare and expensive. Peridot stones with slight inclusions have moderate prices, while those with obvious inclusions are cheaper.
- Weight factor: The price of high-quality large peridots grows exponentially. Peridot stones over 5 carats are very rare, costing over $1,000 per carat.
- Cut quality: Expert cuts enhance a peridot's brilliance and fire, raising its price. Hand-cut unique shapes often carry a premium value.
- Origin source: Those from Zabargad Island in Egypt and Kashmir in Pakistan command the highest prices, while peridots from Arizona in the United States are comparatively less expensive.
- Market trends: Generally, quality 1-3 carat peridots sell for $100 to $500 per carat, while average-quality stones fetch $20 to $100 per carat.

Differences Between Peridot and Other Green Gemstones
Many green gemstones exist in the jewelry market, so knowing how to tell peridot apart is essential.
Emerald: Emeralds belong to the beryl family and are made of beryllium aluminum silicate. Although both are green, peridot gemstones usually have a yellowish-green color, whereas emeralds are often deeper and purer green — the most famous green gemstone. Emeralds are also harder than peridot. Additionally, emerald prices generally exceed those of peridot by a wide margin.
Tourmaline: Green tourmaline, a member of the tourmaline family, consists of complex compounds including sodium magnesium aluminum silicate. Compared to peridot, green tourmalines come in a broader color range, from light to dark green, and show stronger pleochroism (changing colors from different angles). Green tourmalines are a bit harder, rated 7 to 7.5 on the Mohs scale. Peridot is known for its distinctive strong double refraction, while tourmaline's is weaker.
Other beryl family members, like green variants of aquamarine, tend to be lighter in color and more transparent. Their chemical makeup and crystal structure differ completely from peridot gemstone. Synthetic green gemstones, such as lab-created emeralds or green glass, may look similar but can be easily distinguished through professional testing. When purchasing, insist on a professional certificate to make sure you receive genuine natural peridot.
Peridot Jewelry Cleaning and Care
Proper care can keep your peridot jewelry looking beautiful for a long time. Since peridot stone has a relatively low hardness, you should avoid hitting it against hard surfaces during daily wear. It's best to take off your peridot jewelry before intense physical activities, household chores, or when using chemical cleaners.
The best way to clean peridot jewery is to gently brush it with warm soapy water and a soft-bristled brush. Avoid ultrasonic cleaners or steam cleaning because peridot is sensitive to temperature changes. Sudden shifts in temperature can cause gas-liquid inclusions inside the stone to expand and crack. After cleaning, let the peridot jewelry air dry naturally — don't use any drying devices.
When storing your peridot jewelry, keep it separate from harder jewelry like blue topaz, sapphire, or diamonds to avoid scratches. Wrap it in a soft cloth or place it in a dedicated jewelry box. Also, avoid prolonged exposure to strong sunlight. Although peridot gemstone is relatively stable, extended sun exposure can still affect its color over time.
It's also important to regularly check that your settings are secure. If you notice any looseness or damage, have it repaired promptly by a professional jeweler. LUO Jewelry offers free lifetime warranty and our gemstone experts can offer proper care advice to help preserve the value of your peridot jewelry.
