History and Lore
Aquamarine has a rich and storied history that spans across cultures and centuries. Its connection to the sea and its role as a protective stone for sailors are among its most enduring legends. Ancient mariners believed that aquamarine could calm the waves and protect them from the perils of the ocean. This belief was so widespread that the gemstone was often carried on ships or worn by sailors for good luck.
In addition to its maritime associations, aquamarine was also believed to bring happiness in marriage and was thought to provide protection in battle and litigation. The gemstone was associated with courage and clarity of thought, making it a valuable talisman for those seeking to overcome challenges. These beliefs underscore the deep cultural significance of aquamarine and its enduring appeal as a gemstone.
In modern times, aquamarine was officially designated as the birthstone for March in 1912 by the American National Association of Jewelers, now known as Jewelers of America. This designation helped to solidify aquamarine's status as the primary March birthstone and contributed to its popularity in jewelry and gift-giving traditions. Today, aquamarine continues to be a favored gemstone for those born in March, symbolizing renewal, transformation, and the serene beauty of the sea.
Aquamarine is also associated with the 19th wedding anniversary, further highlighting its significance in both personal and cultural contexts. Its enduring legacy as a symbol of protection, clarity, and calmness ensures that it remains a cherished gemstone across generations.
Geological Formation and Sources
Aquamarine is a type of beryl, a mineral that forms in granitic pegmatite rocks under high-temperature conditions. These pegmatites are coarse-grained igneous rocks that form when magma cools slowly, allowing large crystals to develop. The presence of iron in the crystal structure is what gives aquamarine its distinctive blue color. The intensity of the blue hue depends on the amount of iron present, with higher concentrations resulting in deeper, more vibrant colors.
Aquamarine is found in various parts of the world, with Brazil being one of the most significant sources. Brazilian aquamarine is known for its high quality and large sizes, making it a popular choice for fine jewelry. Other notable sources include Afghanistan, Nigeria, Pakistan, and the United States. In the U.S., aquamarine is found in states such as California, Colorado, and New York, although these deposits typically yield smaller stones.
The gemstone is often found in association with other beryl varieties, such as emerald, morganite, and heliodor. This is because the same geological conditions that produce aquamarine can also create these other beryl types, depending on the trace elements present. In some cases, aquamarine may contain inclusions such as mica, hematite, or liquid-filled tubes and hoses. These inclusions can affect the appearance and value of the stone, with cleaner, more transparent specimens being the most desirable.
Aquamarine is typically found in its natural color, but some stones may be heat-treated to enhance their blue tones. This process can remove any yellowish or greenish tints and produce a more consistent and vibrant blue color. While untreated aquamarine is highly valued, heat-treated stones are also considered beautiful and are commonly used in jewelry.
The geological formation and distribution of aquamarine contribute to its unique beauty and value. Its association with the sea, its geological rarity, and its availability in a range of sizes and colors make it a versatile and desirable gemstone for both collectors and jewelry lovers.
Gemological Properties
Aquamarine is a durable and versatile gemstone, with a range of physical and optical properties that make it suitable for a variety of jewelry applications. On the Mohs scale of hardness, aquamarine ranges from 7.5 to 8, making it relatively resistant to scratches and ideal for use in rings, bracelets, and other frequently worn pieces. This hardness is comparable to that of topaz and slightly less than that of corundum (sapphire and ruby), but it is still strong enough to withstand daily wear with proper care.
The gemstone has a refractive index ranging from approximately 1.57 to 1.58 or 1.58 to 1.59, depending on the specific sample. This means that aquamarine can transmit light efficiently, contributing to its clarity and brilliance. It is also uniaxial negative in optical character, meaning that it has one optic axis and exhibits a single direction of light refraction. Some aquamarine specimens may display strong pleochroism, a property that allows the gemstone to show different colors when viewed from different angles. This effect is more pronounced in untreated stones and can add to their visual interest.
Aquamarine has an imperfect cleavage, which means that it can split along certain planes if struck with enough force. This makes it important to handle aquamarine jewelry with care, especially when setting or resizing the pieces. The gemstone also has a vitreous luster, giving it a glass-like appearance that enhances its overall beauty.
In terms of color, aquamarine ranges from pale blues to deep, rich blues, with some stones exhibiting a slight greenish or yellowish tint. The most valuable and sought-after aquamarine is a medium to deep blue with high transparency and minimal inclusions. The presence of inclusions such as mica, hematite, or liquid-filled tubes can affect the appearance and value of the stone. Clean, well-formed aquamarine is typically more valuable and is preferred for high-quality jewelry.
Aquamarine is also known for its pleochroism, a phenomenon in which the gemstone displays different colors when viewed from different directions. This is due to the way light is absorbed and refracted within the crystal structure. Untreated aquamarine may show a range of colors, including pale blue, bright blue, green, and even colorless, depending on the angle of observation. This property can add depth and complexity to the gemstone’s appearance, making it even more visually appealing.
The durability and beauty of aquamarine make it a popular choice for a wide range of jewelry designs. Its versatility allows it to be faceted into a variety of shapes, including emerald cuts, round brilliants, and princess cuts. It is also commonly used in cabochon form for pendants and earrings, where its clarity and color can be showcased in a different way. The gemstone’s ability to reflect and transmit light makes it particularly well-suited for settings that emphasize its brilliance and transparency.
Aquamarine’s gemological properties contribute to its popularity as a birthstone and as a gemstone for fine jewelry. Its hardness, refractive index, and clarity make it a durable and attractive choice, while its pleochroism and color variations add to its visual interest. Whether set in a classic solitaire ring or a more contemporary design, aquamarine is sure to make a beautiful and meaningful addition to any jewelry collection.

One of the most enduring beliefs about aquamarine is its protective power. Ancient sailors carried aquamarine for protection during their voyages, believing that it would calm the seas and keep them safe from shipwrecks and other dangers. This belief was so widespread that aquamarine was often referred to as the "mermaid's stone." The gemstone was also thought to bring good luck and ensure safe travel, making it a valuable talisman for those who spent time at sea.
In addition to its protective qualities, aquamarine is also associated with emotional balance and inner peace. It is believed to help soothe anxiety, reduce stress, and promote a sense of calm. This makes it a popular choice for those seeking to find emotional stability and clarity. Some practitioners of crystal healing use aquamarine to help with communication and self-expression, believing that it can enhance the ability to speak one's truth with confidence and clarity.
Aquamarine is also linked to the throat chakra, which is associated with communication, truth, and self-expression. In this context, the gemstone is thought to help those who struggle with public speaking or expressing their thoughts and feelings. It is believed to encourage honesty, both with oneself and with others, and to promote a sense of trust and openness.
The gemstone is also associated with courage and fearlessness. It is believed to help individuals overcome their fears and face challenges with confidence. This makes it a particularly valuable stone for those who are going through difficult times or who need support in making important decisions.

Care and Cleaning
Aquamarine is a durable gemstone, but it still requires proper care to maintain its beauty and longevity. While it has a high hardness on the Mohs scale (7.5 to 8), it is still susceptible to damage if not handled with care. Its imperfect cleavage means that it can split along certain planes if struck with enough force, so it is important to avoid dropping or knocking aquamarine jewelry.
When cleaning aquamarine jewelry, it is best to use mild soap and warm water. A soft brush can be used to gently scrub the stone and remove any dirt or debris.
