History and Lore
Aquamarine’s history is deeply intertwined with maritime tradition. The name “aquamarine” comes from the Latin words aqua, meaning “water,” and marina, meaning “of the sea,” a fitting description for a gemstone that resembles the color of the ocean. For centuries, aquamarine was believed to offer protection to sailors and travelers at sea. Ancient mariners carried aquamarine with them, believing that it would calm the waters and ensure safe passage.
The gemstone’s association with the sea and protection is reflected in various historical accounts. Roman naturalist Pliny the Elder noted aquamarine’s calming properties and recommended it as a remedy for anxiety and fear. In medieval Europe, aquamarine was used to ward off poison and was believed to promote good health and longevity. It was also considered a symbol of youth and fidelity, often gifted as an engagement or wedding ring to signify lasting love and devotion.
Aquamarine’s journey to becoming a modern birthstone began in the 20th century. As the popularity of birthstone jewelry grew, aquamarine was formally recognized as the birthstone for March. This designation has helped to solidify its place in the world of fine jewelry, with aquamarine being featured in a wide range of designs, from classic solitaire rings to intricate cocktail rings and elegant necklaces.
In addition to its role as a birthstone, aquamarine has been used in various cultural traditions. In some cultures, it is believed to bring clarity of thought and enhance communication, making it a favored stone for those seeking mental focus and emotional balance. These beliefs have contributed to its continued popularity in both historical and contemporary jewelry collections.
Geological Formation and Sources
Aquamarine is a variety of the mineral beryl, which also includes emerald. Its color is due to the presence of iron (Fe²⁺) within the crystal structure. The gemstone forms in igneous and metamorphic rocks, typically in granite pegmatites and hydrothermal veins. The presence of iron in the beryl structure causes the characteristic blue and green hues of aquamarine.
Brazil is the primary source of aquamarine, producing the majority of the world’s supply. The state of Minas Gerais, in particular, is known for its high-quality aquamarine deposits. Other significant sources include Kenya, Madagascar, Malawi, Angola, Nigeria, Mozambique, Pakistan, Tanzania, Russia, Zambia, and parts of Colorado in the United States.
Aquamarine is often found in large crystals, with some of the largest specimens weighing hundreds of pounds. The largest aquamarine ever discovered, for example, weighed approximately 240 pounds and was 19 inches long. These large crystals are often used in museum displays or cut into smaller gemstones for jewelry.
The gemstone’s clarity and color can vary depending on the location and conditions of its formation. Lighter blue aquamarines are more common and generally more affordable, while deeper blue varieties are rarer and more valuable. The presence of inclusions is relatively rare in aquamarine, and when they do occur, they are often not visible to the naked eye.
Aquamarine is often cut into a variety of shapes, including round, oval, emerald, and princess cuts. The gemstone’s hardness makes it suitable for a wide range of jewelry styles, including rings, necklaces, earrings, and bracelets. It is also often paired with other gemstones, such as diamonds or morganite, to create contrasting and complementary designs.
Gemological Properties
Aquamarine is a durable gemstone, with a hardness of 7.5 to 8 on the Mohs scale. This makes it resistant to scratches and suitable for everyday wear, though it is still vulnerable to damage from harder materials like diamonds. Aquamarine is also tough, meaning it can withstand impact without fracturing. However, it can be affected by heat and sudden temperature changes, so it is important to avoid exposing aquamarine to high temperatures or rapid cooling.
The refractive index of aquamarine ranges from 1.56 to 1.58, which contributes to its glassy luster and brilliance. It is also doubly refractive, meaning that it can split light into two rays, a property that can be observed under magnification. This characteristic is often used in gemological testing to identify aquamarine.
Aquamarine is typically colorless in its pure form, and its blue and green hues are the result of trace amounts of iron. The intensity of the color can vary depending on the concentration of iron and the presence of other elements. The most valuable aquamarines have a rich, deep blue color with minimal green tones. These stones are often referred to as “blue water” aquamarines.
The transparency of aquamarine is generally high, with most stones being either transparent or slightly translucent. Inclusions are rare in aquamarine, and when they are present, they are often not visible without magnification. This makes aquamarine an excellent choice for jewelry, as it can be cut into a variety of shapes and sizes without compromising its appearance.
Aquamarine is also known for its pleochroism, a property that allows it to display different colors when viewed from different angles. In some stones, the blue and green tones can appear more pronounced depending on the angle of light. This adds to the gemstone’s visual appeal and makes it a popular choice for collectors and jewelry enthusiasts.
Symbolism and Metaphysical Beliefs
Aquamarine has long been associated with various symbolic and metaphysical properties. In many cultures, it is believed to promote calmness, clarity, and emotional balance. This makes it a popular stone for those seeking to reduce stress, enhance communication, or improve their mental focus. It is also believed to encourage honesty and self-expression, making it a favored choice for those in need of confidence and clarity.
One of the most enduring beliefs associated with aquamarine is its protective qualities. Historically, sailors and travelers carried aquamarine to ensure safe passage and to ward off danger. This belief is still held by some today, with aquamarine being used as a protective talisman for those embarking on new journeys or facing challenging situations.
In addition to its protective qualities, aquamarine is also associated with love and relationships. It is believed to promote harmony, trust, and fidelity in romantic partnerships. Some cultures have used aquamarine as a wedding or engagement stone, symbolizing lasting love and commitment. This association has contributed to its continued popularity in jewelry for special occasions.
Aquamarine is also believed to have healing properties, particularly in relation to the throat and heart chakras. It is thought to help with communication, self-expression, and emotional healing. Some practitioners use aquamarine in meditation and energy work to promote a sense of peace and balance.
While these beliefs are not supported by scientific evidence, they have contributed to the gemstone’s enduring appeal and cultural significance. Whether worn for its symbolic meaning or its aesthetic beauty, aquamarine continues to be a cherished gemstone with a rich history and deep cultural roots.
Care and Cleaning
Despite its durability, aquamarine requires proper care to maintain its beauty and longevity. As with all gemstones, it is important to avoid exposing aquamarine to harsh chemicals, extreme temperatures, or sudden temperature changes. These conditions can cause the gemstone to become cloudy, cracked, or damaged.
Aquamarine jewelry should be cleaned regularly to remove dirt and oils that can dull its luster. A gentle cleaning solution of warm, soapy water can be used to clean aquamarine. The jewelry should be rinsed thoroughly and dried with a soft, lint-free cloth. It is important to avoid using ultrasonic cleaners or steam cleaners, as these can cause damage to the gemstone or its setting.
When storing aquamarine jewelry, it is best to keep it in a soft, breathable pouch or a jewelry box with separate compartments. This helps to prevent scratches and damage from other pieces. Aquamarine should also be stored away from direct sunlight and heat sources to prevent fading or discoloration.
To maintain the gemstone’s brilliance, it is recommended to have aquamarine jewelry professionally cleaned and inspected periodically. A jeweler can check for loose stones, worn settings, and other issues that may affect the piece’s appearance and durability.
When wearing aquamarine jewelry, it is important to avoid activities that may expose the gemstone to impact or abrasion. While aquamarine is relatively hard, it can still be damaged if subjected to excessive force or friction. Removing aquamarine jewelry before engaging in physical activities, such as sports or housework, can help to preserve its condition.
