History and Lore
Aquamarine has a rich and storied history that spans ancient civilizations and continues to influence modern gemology and culture. The gemstone has been revered for its connection to the sea, with many cultures attributing protective and calming properties to it.
Ancient Beliefs and Uses
Ancient Romans believed that aquamarine had healing properties, particularly because it became almost invisible when submerged in water. This unique characteristic led to the belief that the stone could be used to purify or enhance water-related treatments. The Romans also used aquamarine in jewelry, often engraving it with intricate designs and symbols.
In ancient Greece, aquamarine was thought to be a gift from the gods, especially those associated with the sea. Sailors carried aquamarine as a protective charm to ensure safe passage and to ward off the dangers of the ocean. Greek legends claimed that aquamarine washed up on the shores as a natural protective charm for sailors, reinforcing the belief that the stone could calm stormy seas and ensure a safe voyage.
The Egyptians, Greeks, Hebrews, and Sumerians all believed that aquamarine stones were worn by the High Priest of the Second Temple. These stones were said to be engraved to represent the six tribes of Israel, highlighting the gemstone's spiritual and religious significance in ancient times. The Greeks also used aquamarine for engraving intaglios—small carvings used in seals—over two thousand years ago, showcasing its artistic and practical value.
The Birthstone of March
Aquamarine has been recognized as the traditional birthstone for March since at least the 1500s, when jewelers in Germany and Poland began selling birthstone jewelry. The association of aquamarine with March is rooted in its color, which is reminiscent of the ocean and the sky, both of which are often linked to the month of March in many parts of the world.
The tradition of birthstones can be traced back to the 1st century AD, when historians connected biblical lists of 12 stones to the 12 months of the year and the 12 zodiac signs. However, the exact origins of the March birthstone are debated, as early texts did not always specify the same gemstone. In some ancient lists, bloodstone was the only birthstone for March, and it wasn't until the 1800s that aquamarine was officially standardized as the modern March birthstone.
Tiffany & Co. played a significant role in popularizing the concept of birthstones in the 19th century, publishing a list of birthstone poems in 1870. The poem for March emphasized the protective and faithful qualities of the bloodstone, but aquamarine eventually became the more widely accepted and celebrated choice. Today, aquamarine is the dominant March birthstone, while bloodstone remains an alternate option.
Symbolism and Metaphysical Beliefs
Aquamarine is often associated with calmness, courage, and clarity of thought. In many cultures, it is believed to have a soothing effect on the mind and emotions, making it a popular stone for meditation and emotional balance. The gemstone is also associated with the throat chakra in modern metaphysical practices, which is said to enhance communication and self-expression.
In ancient times, aquamarine was believed to have the power to protect sailors and ensure safe voyages across the sea. This belief was reinforced by the idea that the stone was a gift from mermaids, who were thought to guard the treasures of the ocean. The connection between aquamarine and the sea continues to influence its symbolism today, with many people choosing it as a gift to represent friendship, loyalty, and the calming influence of the ocean.
Geological Formation and Sources
Aquamarine is a member of the beryl family, a group of silicate minerals that includes emerald, morganite, and heliodor. Beryl forms in igneous and metamorphic rocks, typically in granitic pegmatites, where the slow cooling of molten rock allows large crystals to develop. The blue color of aquamarine is caused by the presence of iron within the crystal structure, which replaces some of the beryllium atoms in the beryl lattice.
Formation and Occurrence
Aquamarine is formed deep within the Earth's crust, often in granite pegmatites or metamorphic rocks. The presence of iron impurities is responsible for the blue coloration of the gemstone. When exposed to light, the iron atoms absorb certain wavelengths of light, resulting in the characteristic blue to blue-green hues of aquamarine. This process is similar to the way emerald gets its green color from chromium or vanadium.
Aquamarine can be found in a wide range of countries around the world, each with its own unique geological conditions that contribute to the formation of the gemstone. Some of the most notable sources of aquamarine include:
- Brazil: The state of Minas Gerais in Brazil has been a major source of aquamarine for over two centuries. The region is known for producing high-quality, large crystals that are often used in jewelry and museum collections.
- Pakistan: The Karakorum foothills of Pakistan are another significant source of aquamarine. The gemstone found in this area tends to be water-clear and highly prized for its clarity and color.
- United States: Aquamarine is found in several states in the U.S., including California and Colorado. The Mount Antero area of Colorado is particularly well-known for its aquamarine deposits.
- Russia and Ukraine: These countries have a long history of aquamarine mining, with some of the oldest known deposits in the world.
- Asia and Africa: Aquamarine is also found in countries such as China, Myanmar, Zambia, Mozambique, Kenya, Madagascar, Nigeria, and Australia. These regions contribute to the global supply of aquamarine, each offering unique variations in color and clarity.
The availability of aquamarine in these diverse locations has made it a relatively accessible gemstone compared to other colored stones. However, high-quality specimens with intense color and clarity remain rare and valuable.
Gemological Properties
Aquamarine is a durable gemstone that is well-suited for everyday wear, making it a popular choice for jewelry. Its gemological properties, including hardness, cleavage, luster, and refractive index, contribute to its beauty and practicality.
Hardness and Durability
Aquamarine has a hardness of 7.5 to 8 on the Mohs scale, which makes it relatively durable and suitable for use in rings, earrings, and other types of jewelry. However, it is important to note that aquamarine has a perfect cleavage in one direction, which means it can be prone to chipping if struck at the right angle. Therefore, it is recommended to avoid wearing aquamarine jewelry in situations where it may be subjected to hard impacts or rough handling.
Color and Clarity
Aquamarine is known for its soft blue to blue-green hues, which are caused by the presence of iron in the crystal structure. The most desirable specimens have a rich, even blue color with minimal green undertones. The clarity of aquamarine is generally high, with many stones being transparent or slightly translucent. However, inclusions such as mica, hematite, and liquid-filled tubes can be present, especially in lower-quality stones.
Luster and Refractive Index
Aquamarine has a vitreous (glassy) luster, which gives it a bright and sparkling appearance when cut and polished. It is optically uniaxial negative, meaning that it has a single optic axis and exhibits a range of refractive indices. The refractive index of aquamarine typically ranges from 1.57 to 1.58 or 1.58 to 1.59, depending on the specific composition of the stone.
Chemical Composition
Aquamarine is a beryllium aluminum silicate, with the chemical formula Be₃Al₂(Si₆O₁₈). It belongs to the hexagonal crystal system and is often found in large, well-formed crystals. The presence of iron in the crystal structure is responsible for its blue coloration.
Symbolism and Metaphysical Beliefs
Aquamarine has been associated with a wide range of symbolic and metaphysical properties across different cultures and eras. In ancient times, it was believed to have the power to protect sailors and ensure safe passage across the sea. The gemstone was also thought to bring calmness and clarity to the mind, making it a popular choice for meditation and spiritual practices.
Modern Symbolism
In modern times, aquamarine continues to be associated with calmness, courage, and emotional balance. It is often given as a gift to celebrate friendship, loyalty, and the calming influence of the ocean. The gemstone is also believed to enhance communication and self-expression, making it a popular choice for those who work in creative or communicative fields.
Wedding Anniversaries
Aquamarine is the traditional gemstone for the 19th wedding anniversary, symbolizing enduring love and the passage of time. It is also an alternate gemstone for the 14th wedding anniversary, alongside bloodstone.
Care and Cleaning
To maintain the beauty and integrity of aquamarine jewelry, it is important to follow proper care and cleaning procedures. Due to its perfect cleavage and sensitivity to heat, aquamarine should be handled with care to avoid damage.
Cleaning Methods
Aquamarine can be cleaned with warm, soapy water and a soft cloth or brush. Ultrasonic cleaners can be used for quick and effective cleaning, but they should be used with caution, as the vibrations can potentially damage the stone if it has inclusions or is of low quality. Steam cleaning is not recommended for aquamarine, as the heat can cause the liquid inclusions to expand and potentially crack the stone.
Storage and Handling
Aquamarine should be stored separately from other gemstones to prevent scratches and abrasions. It is best to store it in a soft cloth or a padded jewelry box to protect it from dust and physical damage. When wearing aquamarine jewelry, it should be avoided in situations where it may be exposed to hard impacts or extreme temperatures.
