Introduction
August's birthstones—peridot, spinel, and sardonyx—each tell a story of their own. Peridot, with its radiant green hue, is often called the “gem of the sun” and has been prized for millennia for its beauty and uplifting properties. Spinel, with its brilliant range of colors, has only recently gained recognition as a distinct gemstone in its own right, often mistaken for ruby in the past. Sardonyx, the oldest of the August birthstones, boasts a long history of use in ancient civilizations and is revered for its protective qualities and earthy charm.
The inclusion of multiple birthstones for a single month is a relatively modern phenomenon, made possible by the evolving standards of gemstone classification and the desire to offer consumers a broader range of choices. Today, peridot remains the official August birthstone, while spinel and sardonyx are recognized as secondary or alternative options. This diversity allows August-born individuals to choose a stone that best aligns with their personal style, energy, and values.
In the following sections, we will explore the history and cultural significance of each of these gemstones, examine their geological properties, and discuss how they are best cared for and appreciated in modern jewelry. Whether you are seeking to understand the meaning behind these stones or simply wish to deepen your appreciation for gemology, this article will provide a comprehensive and authoritative look at the August birthstones.
History and Lore
Peridot: The Sun's Gift
Peridot has been cherished since ancient times and has a rich history that spans multiple civilizations. The gemstone's name comes from the Arabic word faridat, meaning "gem," and it has long been associated with light, warmth, and positivity. One of the most fascinating aspects of peridot is that it can be found not only on Earth but also in meteorites. This extraterrestrial origin adds to its mystique and reinforces its connection to the sun.
Historically, peridot was often confused with other green gemstones such as emerald and topaz. In fact, the famous Shrine of the Three Holy Kings in Cologne Cathedral, Germany, contains what were once believed to be emeralds, but are now identified as peridot. This misidentification highlights the gem's similarity to other precious stones and underscores its value in historical contexts.
Ancient Egyptians referred to peridot as the "Evening Emerald" due to its brilliant green color and its ability to shine in moonlight. Pharaohs used peridot in their jewelry and amulets, believing it to offer protection and bring abundance. In medieval Europe, peridot was thought to ward off nightmares and bring happiness and strength to its wearer. These beliefs speak to the stone's enduring appeal as a symbol of hope and positivity.
Spinel: The Overlooked Gem
Spinel is a relatively recent addition to the official list of birthstones, having been recognized as an August birthstone in 2016. Before this, it was often mistaken for ruby, a misidentification that led to many historical specimens being labeled incorrectly. Spinel is a mineral composed of aluminum and magnesium oxides and is known for its wide range of colors, including red, pink, orange, blue, and even black.
The confusion between spinel and ruby can be attributed to their similar appearance and chemical composition. In fact, some of the most famous "rubies" in history, such as the "Black Prince's Ruby" in the British Crown Jewels, are actually red spinel. This misclassification persisted for centuries, and it was only through advances in gemology that spinel was recognized as a distinct and valuable gemstone in its own right.
Spinel's recent recognition as an August birthstone has brought renewed attention to its beauty and versatility. It is now celebrated for its vibrant colors and durability, making it an excellent choice for modern jewelry. Its royal history adds to its allure, and its growing popularity reflects a shift in consumer preferences toward unique and meaningful gemstones.
Sardonyx: The Stone of Strength
Sardonyx is the oldest of the three August birthstones, with a history that dates back over 4,000 years. This banded chalcedony is composed of layers of red and white or brown and white, giving it a distinctive and elegant appearance. Sardonyx has been used in ancient jewelry and amulets across various cultures, including Egyptian, Greek, and Roman civilizations.
In ancient Egypt, sardonyx was valued for its protective qualities and was often used in seals and amulets. The Greeks and Romans believed that sardonyx could bring courage, strength, and stability to its wearer. It was also thought to support healthy relationships and promote trust and loyalty between partners. These beliefs have persisted through the ages and continue to influence the stone's modern symbolism.
Sardonyx has a long tradition in Western jewelry, particularly in Victorian and Art Deco designs. Its earthy tones and elegant banding make it a versatile gemstone that complements both vintage and contemporary styles. As one of the original August birthstones, sardonyx remains a symbol of resilience and enduring strength, making it a meaningful choice for those born in this month.
Geological Formation and Sources
Peridot: Earth and Sky
Peridot is a gem variety of the mineral olivine, a magnesium iron silicate. It is formed under extreme conditions deep within the Earth’s mantle, often brought to the surface through volcanic activity. The intense heat and pressure required for peridot’s formation give it a unique composition and vibrant green color.
Peridot is found in a variety of locations around the world, including the United States, Brazil, China, and Pakistan.
