History and Lore of the July Birthstones
The concept of birthstones dates back thousands of years, with roots in ancient traditions that linked specific gemstones to months of the year. The July birthstone, in particular, has a rich and varied history. While ruby has long been regarded as the primary birthstone for July, moonstone is also associated with the month, particularly in certain astrological and spiritual traditions.
Ruby: A Stone of Passion and Power
Ruby, the most prominent July birthstone, has been revered for its deep red color and symbolic meaning since antiquity. Known as the "king of gems," ruby has been prized by royalty and warriors alike for its association with vitality, courage, and passion. In ancient cultures, ruby was believed to bring protection, ward off evil, and enhance one’s vitality. It was often worn by kings and generals as a symbol of strength and divine favor.
In medieval Europe, ruby was considered a powerful talisman. It was believed to bring success in love and war, and to protect the wearer from disease and poison. In India, ruby has been a sacred gemstone for centuries, associated with the sun and considered a symbol of prosperity and power.
Ruby's allure has persisted into modern times. The stone remains a popular choice for engagement rings, pendants, and other fine jewelry, especially among those born in July. Its enduring appeal lies in its vibrant color and timeless elegance, making it a gemstone that transcends cultural and historical boundaries.
Moonstone: A Stone of Intuition and Serenity
While ruby is the traditional July birthstone, moonstone is also associated with the month in certain astrological and spiritual traditions. Moonstone is particularly linked to the zodiac sign Cancer, which spans from June 21 to July 22. As a water sign ruled by the moon, Cancer is characterized by its nurturing nature, deep emotional connections, and intuitive abilities—qualities that moonstone is believed to enhance.
Moonstone has a long history of use in jewelry and talismans. In ancient Rome, moonstone was believed to have fallen from the moon and was associated with Diana, the goddess of the moon and the hunt. In India, moonstone is one of the Navaratnas (nine sacred gemstones) and is linked to the moon in Vedic astrology. It is believed to bring calm, emotional balance, and protection during travel.
Moonstone's ethereal sheen and soft glow make it a captivating gemstone, often used in rings, pendants, and bracelets. It is especially popular in bohemian and artisanal jewelry, where its mystical aura and gentle energy are celebrated.
Geological Formation and Sources
Understanding the origins and properties of a gemstone is essential for appreciating its value and beauty. Both ruby and moonstone have distinct geological characteristics and are found in specific regions around the world.
Ruby: A Corundum with a Crimson Hue
Ruby is a variety of the mineral corundum, which also includes sapphire. Its deep red color is caused by the presence of chromium or iron within its crystalline structure. Ruby's hardness is rated at 9 on the Mohs scale, making it one of the hardest and most durable gemstones, second only to diamond.
The finest rubies are known for their "pigeon's blood" red color, a term used to describe a vivid, slightly bluish red hue with a high degree of saturation. These exceptional stones are most commonly found in Myanmar (Burma), where they have been mined for centuries. Other notable sources of ruby include Mozambique, Thailand, Sri Lanka, and Madagascar. Smaller deposits are also found in the United States, particularly in North Carolina.
Rubies form in metamorphic rocks, typically in regions where aluminum-rich minerals are subjected to high pressure and temperature. The presence of chromium or iron impurities gives the stone its characteristic red color. The rarity of high-quality rubies, particularly those with the ideal "pigeon's blood" hue, contributes to their high value in the gemstone market.
Moonstone: A Feldspar with a Luminous Luster
Moonstone is a type of feldspar, a group of minerals that make up a significant portion of the Earth's crust. Its most distinctive feature is its adularescence, a soft, billowing light that appears to float just beneath the surface of the stone. This effect is caused by the interference of light with the microscopic layers of feldspar, creating a shimmer that resembles moonlight on water.
Moonstone is most commonly found in India and Sri Lanka, where it has been used in jewelry and talismans for centuries. Other sources include Madagascar, Brazil, and the United States, particularly in the state of North Carolina. The finest moonstones are typically white and blue in color, although they can also appear in other hues such as yellow, orange, and green.
Moonstone forms in pegmatite deposits, a type of igneous rock that cools slowly and allows large mineral crystals to develop. The presence of orthoclase and albite feldspars within these deposits is responsible for the stone's unique optical properties. While moonstone is more abundant than ruby, high-quality specimens with strong adularescence are still considered valuable and are often used in fine jewelry.
Gemological Properties
Understanding the gemological properties of ruby and moonstone is essential for appreciating their beauty and durability. These properties include hardness, chemical composition, refractive index, and other physical characteristics that influence their use in jewelry and their value in the gemstone market.
Ruby: The Hard and Radiant Red Gem
Hardness:
Ruby ranks 9 on the Mohs Hardness Scale, making it highly durable and suitable for everyday wear in jewelry such as rings, pendants, and bracelets.
Chemical Composition:
Ruby is composed of aluminum oxide (Al₂O₃) with trace amounts of chromium or iron responsible for its red color. The presence of these trace elements determines the intensity and hue of the stone.
Refractive Index and Luster:
Ruby has a refractive index of approximately 1.76–1.78, with a glassy to adamantine luster. Its high refractive index and strong dispersion contribute to its brilliance and fire, making it an exceptionally beautiful gemstone.
Color Saturation and Clarity:
The most valuable rubies exhibit deep red to slightly bluish red coloration with high saturation. Clarity is also important, although inclusions are common in natural rubies and can be characteristic of their origin.
Cutting and Shape:
Rubies are typically cut into emerald, oval, round, and princess shapes to maximize their brilliance and color. The "pigeon's blood" cut is a specialized technique used to enhance the color and clarity of the finest rubies.
Market Value and Rarity:
Rubies are among the most valuable gemstones in the world, with high-quality stones fetching prices in the millions of dollars per carat. The "pigeon's blood" rubies from Myanmar are particularly sought after due to their exceptional color and historical significance.
Moonstone: The Soft and Shimmering Gem
Hardness:
Moonstone has a lower hardness than ruby, ranking 6–6.5 on the Mohs Hardness Scale. This makes it more delicate and prone to scratching or chipping, especially in rings and other jewelry that may be subjected to daily wear.
Chemical Composition:
Moonstone is a type of feldspar, specifically a potassium aluminum silicate (KAlSi₃O₈). Its adularescence is caused by the presence of orthoclase and albite feldspars in alternating layers within the stone.
Refractive Index and Luster:
Moonstone has a refractive index of approximately 1.518–1.526, with a pearly to vitreous luster. Its most distinctive feature is its adularescence, a soft, shimmering light that appears to move across the surface of the stone.
Color and Clarity:
The most desirable moonstones are white and blue, with a strong, even adularescence. Other colors include yellow, orange, and green, though these are less common. Clarity is generally good, though inclusions are often visible in moonstone.
Cutting and Shape:
Moonstone is typically cut into oval, round, and cabochon shapes to enhance its shimmer and color. The cabochon cut is particularly popular for moonstone, as it allows the adularescence to be fully visible.
Market Value and Rarity:
While moonstone is more abundant than ruby, high-quality specimens with strong adularescence are still considered valuable. The finest moonstones from India and Sri Lanka are especially prized for their beauty and rarity.
