History and Lore
Peridot: The Gem of the Sun
Peridot has a history that stretches back thousands of years, with evidence of its use dating to as early as 1500 BC. Ancient Egyptians, Chinese, and Romans all valued peridot for its beauty and believed in its magical properties. The gem was known as "the gem of the sun" in Egypt, and it was believed to glow in the dark when set in a dark environment. This belief may have originated from the way peridot crystals were mined in the Red Sea hills near the island of Zabargad. The name "peridot" is derived from the Greek word "peridona," meaning "giving plenty," which refers to the green fields of summer that the stone resembles.
During the Middle Ages, peridot was associated with fertility and was often worn by women during childbirth. It was also believed to increase milk production in cows and aid in the healing of wounds. These beliefs, while not supported by modern science, reflect the deep cultural and symbolic significance of peridot in various historical contexts.
In the 20th century, peridot gained further recognition as a popular birthstone. It became the traditional birthstone for August and has since remained a beloved gemstone in jewelry design. In 1911, peridot was designated as the official gemstone for the 16th anniversary of marriage, further cementing its place in cultural traditions.
Sardonyx: A Stone of Protection and Eloquence
Sardonyx, a red and white banded variety of chalcedony, has an equally ancient lineage. Its popularity dates back to the Second Dynasty of Egypt, more than 4,000 years ago. The ancient Greeks and Romans prized sardonyx for its protective qualities and often wore it as a talisman engraved with images of gods. The Egyptians believed it had the power to heal the body, particularly the bones, and it was commonly used in amulets and seals.
During the Renaissance, sardonyx was associated with eloquence and was worn by public speakers and orators to promote clear thinking and effective communication. This belief in its power to enhance speech and clarity of thought continued into the 18th and 19th centuries, when sardonyx was often set in rings and pendants worn by scholars and statesmen.
Sardonyx also has a rich tradition in Western Europe, where it was used in cameos and intaglios. The stone's contrasting bands of red and white made it an ideal medium for intricate carvings, and many of these pieces have survived to the present day. Sardonyx was the original August birthstone, and it continues to be valued for its historical significance and enduring beauty.
Spinel: The Newcomer to the August Birthstone Family
Spinel is the newest addition to the August birthstone family, having been officially recognized in 2016. Despite its relatively recent inclusion, spinel has a long and fascinating history. For centuries, it was often mistaken for ruby or sapphire due to its similar appearance and color range. Some of the most famous "rubies" in history were actually spinel, including the "Black Prince's Ruby" in the British Crown Jewels and the "Timur Ruby."
Spinel is a versatile gemstone that comes in a wide array of colors, including red, pink, orange, yellow, green, blue, and purple. Its brilliance and clarity make it a popular choice for jewelry, and its durability (it ranks 8 on the Mohs scale) means it is well-suited for everyday wear. The addition of spinel to the August birthstone list has expanded the options for those born in August, offering a new and exciting gemstone to choose from.
Geological Formation and Sources
Peridot
Peridot is a type of olivine, a mineral composed of magnesium iron silicate. It forms in volcanic rocks in the Earth's upper mantle, a process that distinguishes it from many other gemstones, which form closer to the Earth's surface. The presence of iron in the stone is responsible for its green color, with the most prized peridots being those with a vibrant green hue and minimal yellow or brown tones.
Peridot is found in a variety of locations around the world, including the United States, Brazil, Egypt, China, and Pakistan. In the U.S., peridot is particularly abundant in Arizona, where it is the state gemstone. The finest peridots are often sourced from Pakistan, where they are known for their exceptional color and clarity. These stones can rival the value of diamonds and are highly sought after by collectors and jewelers alike.
Sardonyx
Sardonyx is a banded variety of chalcedony, a form of quartz composed of silicon dioxide. The red bands in sardonyx are due to the presence of iron oxide, while the white bands are composed of pure silica. The stone is formed through the slow deposition of silica in sedimentary rocks, often in the presence of iron-rich minerals that create the characteristic banding.
Sardonyx is found in various parts of the world, including India, Brazil, Madagascar, and the United States. India is one of the most significant sources of sardonyx, particularly for the production of cameos and intaglios. The stone's durability and ease of carving make it ideal for intricate designs, and it has been used in jewelry and decorative objects for centuries.
Spinel
Spinel is a mineral composed of magnesium aluminum oxide, and it forms in a variety of geological environments, including igneous and metamorphic rocks. The presence of trace elements such as chromium, iron, and cobalt gives spinel its wide range of colors. Red spinels, for example, owe their hue to chromium, while blue spinels get their color from cobalt.
Spinel is found in several countries, including Myanmar, Sri Lanka, Tanzania, Vietnam, and Brazil. Myanmar is particularly known for producing high-quality red spinels, while Tanzania is a major source of pink and orange spinels. The versatility of spinel as a gemstone has made it a popular choice among jewelers, and its relatively affordable price compared to similar-colored gemstones like ruby or sapphire has contributed to its growing popularity.
Gemological Properties
Peridot
Peridot is a gemstone with a relatively high hardness, ranking between 6.5 and 7 on the Mohs scale. This makes it durable enough for everyday wear, although it is not as hard as diamonds or corundum (such as rubies or sapphires). Peridot has a refractive index of 1.65 to 1.69 and a specific gravity of 3.30 to 4.58, depending on its composition. Its transparency ranges from transparent to translucent, and it is often cut into faceted stones to enhance its brilliance.
One of the unique characteristics of peridot is its pleochroism, meaning it can display different colors when viewed from different angles. This is particularly noticeable in stones with a high iron content. Peridot is also known for its inclusions, which can be seen as small, needle-like structures within the stone. These inclusions are not flaws but rather natural features that add to the gem's character and authenticity.
Sardonyx
Sardonyx has a hardness of 6.5 to 7 on the Mohs scale, making it relatively durable for a gemstone. It is composed of two distinct layers: a red layer of sard (a type of chalcedony containing iron oxide) and a white layer of onyx (pure silica). This banding gives sardonyx its distinctive appearance and makes it well-suited for carving and engraving.
Sardonyx has a refractive index of 1.53 to 1.54 and a specific gravity of 2.58 to 2.61. It is typically opaque or translucent, and it is most commonly cut into cabochons or used in cameos and intaglios. The stone's durability and ease of carving have made it a popular choice for engraved jewelry and decorative objects throughout history.
Spinel
Spinel is a relatively hard gemstone, with a hardness of 8 on the Mohs scale. This makes it highly durable and suitable for a wide range of jewelry applications, including rings, necklaces, and bracelets. Spinel has a refractive index of 1.718 to 1.736 and a specific gravity of 3.98 to 4.10, depending on its composition. It is typically transparent to translucent and is known for its brilliance and clarity.
One of the most notable properties of spinel is its high refractive index, which gives it a bright, fiery luster. Spinel is also known for its excellent color saturation, making it an ideal gemstone for showcasing vibrant hues. Unlike many other gemstones, spinel does not have cleavage, making it less prone to chipping or breaking. This durability, combined with its beauty, makes spinel a popular choice for both everyday and special occasion jewelry.
