August Birthstone – Peridot

Peridot stands as one of the most fascinating gemstones in the world of jewelry, captivating people for over 4,000 years with its distinctive olive-green hue. As August’s birthstone, it carries both historical significance and modern appeal, making it a gem that transcends time. Whether discovered in the hearts of volcanoes or carried to Earth by meteorites, peridot’s formation story is as unique as its color.

What is Peridot?

Peridot is a gem-quality variety of the mineral olivine, formed under extreme temperatures in the Earth’s mantle approximately 20-55 miles beneath the surface. Unlike many gemstones that come in various colors, peridot is idiochromatic, meaning its green color comes from its essential chemical composition – mainly iron – rather than trace impurities. This makes it one of the few gemstones that occurs in only one color, though its intensity and tint can vary from yellow-green to olive to brownish-green.

The stone’s internal structure creates a double refraction effect, meaning each ray of light entering the stone is split into two. This optical property gives peridot its characteristic velvety appearance and makes it appear to glow from within, especially in natural light.

Origin and Formation

The journey of peridot from deep within the Earth to adorning jewelry is a testament to nature’s incredible forces. Most peridot forms in magma in the upper mantle, around 20-55 miles below the Earth’s surface, under extreme temperatures of 1,000°C (1,832°F). The gems reach the surface through volcanic activity or tectonic events that force mantle rocks upward.

• Volcanic Sources: The majority of commercial peridot comes from volcanic areas. These deposits formed when mineral-rich magma solidified, creating peridot crystals within basalt rock formations. Over time, weathering exposes these crystals.
• Meteoritic Sources: Some peridot comes from pallasite meteorites, making it literally extraterrestrial. These rare specimens contain peridot crystals embedded in an iron-nickel matrix, creating stunning specimens that bridge the gap between Earth and space.
• Historic Locations: The ancient Egyptians mined peridot on Zabargad Island (now St. John’s Island) in the Red Sea, which produced some of the finest specimens in history. These mines, active for over 3,500 years, supplied gems to ancient Egypt’s royalty.

Physical Properties and Characteristics

Understanding peridot’s physical properties helps appreciate both its beauty and required care. This gemstone’s unique characteristics influence everything from its appearance to its durability in jewelry.

1. Crystal Structure: Peridot belongs to the orthorhombic crystal system, forming prismatic crystals that can range from small grains to large, transparent specimens suitable for faceting.
2. Hardness and Durability: With a Mohs hardness of 6.5-7, peridot is softer than many popular gemstones like sapphire or diamond. This moderate hardness means it requires proper care to maintain its luster and avoid scratches.
3. Color and Transparency: The finest specimens display a bright lime-green to olive-green color with excellent transparency. The most valued stones show minimal brown tints and possess high clarity with few internal inclusions.
4. Optical Properties: The stone’s high birefringence creates a distinctive optical effect, sometimes visible as a subtle doubling of facet edges when viewed through the crown.
5. Size Range: Natural peridot crystals can range from tiny grains to large specimens. Faceted stones typically range from 1 to 8 carats, though larger examples exist.

Given these physical characteristics, peridot requires thoughtful consideration in both jewelry design and daily wear. While it may not be as hard as some precious gems, its unique optical properties and enchanting color make it an excellent choice for occasional wear jewelry like pendants, earrings, and special occasion rings. Understanding these properties helps jewelry enthusiasts make informed decisions about purchasing and caring for their peridot pieces.

Peridot as a Birthstone

The tradition of birthstones has deep historical roots, and peridot holds a special place as August’s designated gem. This association brings additional meaning and significance to peridot jewelry, especially for those born in the late summer month.

• Birthstone History: Peridot’s designation as August’s birthstone dates back to the Talmud, where each month was associated with a specific gem. This connection was later standardized in 1912 by the National Association of Jewelers, cementing peridot’s status as August’s primary birthstone.
• Traditional Meanings: As a birthstone, peridot is believed to bring its August-born wearers special benefits:
  • Protection from nightmares and negative thoughts
  • Enhancement of confidence and leadership abilities
  • Promotion of emotional well-being and balanced relationships
  • Connection to nature and natural cycles
  • Strengthening of the mind-body connection
• Modern Celebrations: Today, peridot serves as a meaningful gift for:
  • August birthdays
  • 16th wedding anniversaries
  • New parents of August-born children
  • Summer celebrations and commemorations
  • Graduation gifts for August graduates
• Cultural Significance: Different cultures view August’s birthstone through unique lenses:
  • Western traditions see it as a symbol of prosperity and good fortune
  • Eastern philosophies connect it to harmony and balance
  • Pacific Island cultures associate it with volcanic creation and renewal
  • Modern interpretations link it to environmental awareness and sustainability

Understanding peridot’s role as a birthstone adds another layer of meaning to this already fascinating gem, making it particularly special for August-born individuals and those who wish to celebrate them.

Value and Quality Factors

Professional gemologists and jewelry experts evaluate peridot using several key criteria that determine its value and desirability in the market. While all gemstones are assessed based on the traditional “Four Cs” (color, clarity, cut, and carat weight), peridot has its own unique set of qualities that make certain specimens more valuable than others.

• Color Assessment: The most valuable peridot displays a rich olive-green color with a slight golden tint, free from brown or yellowish overtones. Iron content directly influences the intensity of the green color – the more iron present, the deeper the green. The finest specimens show excellent saturation and an even color distribution throughout the stone.
• Clarity Standards: Unlike many gemstones where inclusions are common, high-quality peridot should be relatively free from visible internal features. Common inclusions in peridot include tiny black chromite crystals, disc-like “lily pad” inclusions, and liquid-filled cavities. Top-grade stones should be “eye-clean,” meaning no visible inclusions when viewed with the naked eye.
• Cutting Considerations: Expert cutting is crucial for peridot, as proper orientation of the crystal during cutting can enhance its apparent color and brilliance. The best cuts showcase the stone’s double refraction while minimizing the appearance of any internal inclusions.
• Size Impact: While peridot can be found in various sizes, stones over 10 carats are considerably rare and command premium prices. The relationship between size and value isn’t linear – exceptional stones of 5 carats or more can see dramatic price increases per carat.

Understanding these quality factors helps collectors and jewelry enthusiasts make informed decisions when selecting peridot pieces, ensuring they receive the best value for their investment while choosing stones that will maintain their beauty over time.

Historical Significance

The rich history of peridot stretches back to the earliest civilizations, where it played significant roles in both decoration and mythology. This gemstone’s journey through time reveals fascinating stories of ancient trade routes, royal collections, and cultural beliefs that continue to influence its appreciation today.

1. Ancient Egyptian Connection: The Egyptians were among the first to mine peridot systematically, extracting it from Zabargad Island as early as 1500 BCE. These early miners worked primarily at night, believing the stones were easier to locate by moonlight when they glowed against the dark rocks. The gems they recovered adorned the regalia of Egyptian pharaohs and high priests.
2. Medieval European History: During the Crusades, peridot made its way to European cathedrals and royal treasuries. Many stones initially thought to be emeralds were later identified as peridot, including some gems in the Three Holy Kings shrine at Germany’s Cologne Cathedral.
3. Hawaiian Cultural Significance: Native Hawaiians associated peridot with Pele, their volcano goddess. They believed the gems were her tears, crystallized by the intense heat of volcanic activity. This connection to volcanic creation remains part of the stone’s modern mystique.
4. Trade Route Importance: Peridot became a valuable trade commodity along the ancient Silk Road, connecting Eastern and Western civilizations through gem commerce. Merchants transported the stones from Egyptian mines to markets in Europe and Asia, where they were prized for both their beauty and supposed protective powers.

This extensive history demonstrates peridot’s enduring appeal across cultures and centuries, contributing to its continued significance in modern jewelry design and collection.
