The month of August brings with it the bright green glow of peridot, the official birthstone for those born in this summer month. Known for its distinctive green hue, peridot is one of the few gemstones that occur in only one color, although the intensity and tint of the green depend on the amount of iron contained in the crystal structure. This captivating gemstone has a rich history, fascinating geology, and an abundance of symbolic meanings that make it a cherished stone for many. A Brief History of Peridot Peridot has been adored for thousands of years, with its use dating back to ancient Egypt around 1500 BC. It was known as the “gem of the sun” and was believed to protect against nightmares and bring the wearer confidence, health, and positive energy. The ancient Egyptians sourced their peridot from the volcanic island of Zabargad in the Red Sea. This island remained a significant source of peridot until the early 20th century. During the Middle Ages, peridot was highly valued by European royals and clergy and was often used to decorate church altars and clerical robes. The stone's popularity continued through the Victorian era, where it was frequently used in jewelry. The Science Behind Peridot Peridot is a gem-quality variety of the mineral olivine, a silicate mineral rich in magnesium and iron. It forms deep within the Earth’s mantle and is brought to the surface by volcanic activity. This geological process means that peridot is often found in areas with significant volcanic history, such as Hawaii, Arizona, and parts of China and Myanmar. The gem’s signature green color is due to the presence of iron within its structure, and it ranges from a yellowish-green to a more intense olive or brownish-green. Unlike many other gemstones, peridot's color is innate, not caused by impurities, which means it doesn't change color under different lighting conditions. Unique Inclusions: The Lily Pad One of the most fascinating aspects of peridot is its unique inclusions, commonly referred to as "lily pad inclusions." These inclusions are typically small, circular shapes resembling lily pads floating on water, and they are caused by minute cracks, or other minerals, such as chromite, within the gemstone. While some might view inclusions as imperfections, lily pad inclusions add character to the peridot and can enhance its allure by adding depth and a unique texture to the gem. These inclusions are often considered identifying marks that authenticate natural peridot stones. (See photo below) Symbolism and Meaning The vibrant green of peridot symbolizes growth, renewal, and new beginnings, making it a fitting stone for August, a month associated with the harvest. It is also associated with the sun, and is thought to drive away the darkness and bring warmth and light. In terms of emotional healing, peridot is said to promote abundance, prosperity, and happiness. It’s believed to alleviate jealousy, resentment, and stress, replacing negative energies with positivity and clarity. Caring for Peridot Jewelry Peridot, with a Mohs hardness of 6.5 to 7, is softer than many other gemstones, so it requires careful handling. To keep peridot jewelry looking its best, clean it gently with mild soap and warm water, and avoid ultrasonic cleaners and harsh chemicals. It’s best to store peridot pieces separately from other harder gemstones to prevent scratching. Where to Find Peridot Today, major sources of peridot include the United States, particularly Arizona, China, Myanmar, and Pakistan. The Peridot Mesa in Arizona's San Carlos Reservation is one of the most prolific sources of gem-quality peridot in the world. The finest peridot stones often come from Pakistan’s mountainous Kashmir region, where exciting, large crystals are found. Peridot is not just a beautiful gemstone but a symbol of warmth, peace, and growth.
