History and Lore
Aquamarine: The Soul of the Sea
Aquamarine, whose name derives from the Latin aqua marina meaning "seawater," has been treasured since ancient times for its association with the sea. Ancient mariners believed aquamarine could calm the waves and protect sailors during their journeys. It was also considered a symbol of courage and was worn by Celtic warriors to inspire bravery on the battlefield.
The gemstone's calming effect and connection to water have led to various myths and legends. Some ancient cultures believed that aquamarine was formed from the tears of mermaids or from the foam of the sea. In medieval Europe, aquamarine was thought to bring happiness in marriage, and newlyweds exchanged the gemstone as a symbol of enduring love and fidelity.
Aquamarine’s role as a birthstone began to evolve in the 20th century. Originally, Bloodstone was the sole March birthstone, chosen for its symbolism of the spring equinox and rebirth. However, in 1952, as aquamarine gained popularity in the jewelry world, it was added to the list of March birthstones. The blue hue of aquamarine was associated with "spring’s first waters," representing a fresh start and renewal. This led to the unique tradition of having two birthstones for March, each with its own distinct symbolism and properties.
Bloodstone: The Blood of the Earth
Bloodstone, also known as Heliotrope, has a long and storied history. Its name comes from the red flecks that resemble drops of blood on its green base. The gemstone was believed to have curative properties and was used in ancient times for medicinal purposes. The ancient Greeks and Romans associated bloodstone with health and vitality. It was also considered a protective stone for warriors and travelers.
According to legend, bloodstone was formed when the blood of Christ fell upon the earth during the crucifixion. This myth contributed to its reputation as a symbol of sacrifice and strength. In medieval Europe, bloodstone was used in healing practices and was believed to stop bleeding and promote recovery from injuries. It was also used in amulets to ward off the "evil eye" and to protect the wearer from harm.
In the 20th century, bloodstone continued to be valued for its symbolic and practical uses. Luxury Swiss watch brand Hublot released a limited-edition watch with a bloodstone dial in honor of its connection to "time and life." Scientific research has also explored the potential of bloodstone in modern applications, such as the use of its iron oxide content to block certain electromagnetic waves, which could lead to its use in medical device coatings.
Geological Formation and Sources
Aquamarine: From the Depths of the Earth
Aquamarine is a variety of the mineral beryl, a beryllium aluminum silicate with a chemical composition of Be₃Al₂(SiO₃)₆. Its blue color is due to the presence of trace amounts of iron (Fe) within the crystal structure. The intensity of the blue color can vary depending on the concentration of iron and the presence of other trace elements.
Aquamarine is formed deep within the Earth's crust through the slow cooling of magma in igneous rocks. It is often found in granite pegmatites and in metamorphic rocks. The crystal structure of aquamarine is hexagonal, and the gemstone is typically found in elongated, prismatic crystals.
The primary sources of aquamarine include:
- Brazil: The most important source of aquamarine in the world. The gemstone is often found in the states of Minas Gerais, Espírito Santo, and Bahia.
- Madagascar: Known for producing high-quality aquamarine with vibrant blue colors.
- Nigeria and Pakistan: Also significant sources of aquamarine, with deposits in various regions.
Aquamarine is known for its clarity and is often free of inclusions, making it highly desirable in the jewelry industry. It has a Mohs hardness of 7.5 to 8, which makes it relatively durable and suitable for everyday wear.
Bloodstone: A Stone of Strength
Bloodstone is a type of chalcedony, a microcrystalline variety of quartz (SiO₂). It is typically found in a dark green or gray-green base with red or reddish-brown speckles. These red flecks are due to the presence of iron oxide (Fe₂O₃), which gives bloodstone its characteristic appearance.
Bloodstone is formed through the sedimentation and compaction of silica-rich materials over millions of years. It is often found in sedimentary rocks and is associated with deposits of chert and flint. The iron oxide in bloodstone can form through the oxidation of iron-bearing minerals during the formation process.
The primary sources of bloodstone include:
- India: The most important source of bloodstone, particularly in the state of Jammu and Kashmir.
- China and the United States: Also produce bloodstone, with deposits found in various regions.
Bloodstone has a Mohs hardness of 6.5 to 7, making it suitable for use in jewelry and carvings. It is often cut as a cabochon, which enhances its chatoyancy (cat's-eye effect) and the visibility of the red flecks.
Gemological Properties
Aquamarine: A Gem of Clarity and Strength
Aquamarine is prized for its clarity, brilliance, and durability. Its hexagonal crystal structure gives it a trigonal symmetry, and it is typically cut in a facetted style to enhance its refractive properties. Common cuts include the emerald cut, oval cut, marquise cut, and pear shape. These cuts help to maximize the gemstone’s light return and color saturation.
The color of aquamarine ranges from pale icy blue to deep ocean blue. Some stones have a subtle greenish tint, adding depth and complexity to the color. The presence of iron impurities is responsible for the blue coloration, and the intensity of the color can vary depending on the concentration of iron and the presence of other trace elements.
Aquamarine has a refractive index of 1.57 to 1.60, which gives it a vitreous (glassy) luster. It is relatively inclusion-free, which contributes to its clarity and brilliance. However, some stones may contain minor inclusions such as tiny gas bubbles or needle-like crystals of other minerals.
Aquamarine has a Mohs hardness of 7.5 to 8, making it suitable for use in jewelry. It is also relatively stable in terms of toughness, although it can be susceptible to chipping if struck with a hard object. The gemstone is anisotropic, meaning it exhibits birefringence (double refraction), which can cause a slight doubling effect when viewed through the stone.
Bloodstone: A Stone of Resilience
Bloodstone is a microcrystalline quartz with a hexagonal crystal structure. It is typically cut as a cabochon, which enhances its chatoyancy and the visibility of the red flecks. The cabochon cut is particularly effective in showcasing the cat’s-eye effect, which is caused by the aligned fibrous structure of the chalcedony.
The color of bloodstone is characterized by a dark green or gray-green base with red or reddish-brown speckles. The red flecks are due to the presence of iron oxide, and the contrast between the red and green gives bloodstone a vivid and mysterious appearance.
Bloodstone has a refractive index of 1.53 to 1.54, which gives it a vitreous (glassy) luster. It is relatively inclusion-free, with the exception of the red flecks that are part of its natural composition. The gemstone is relatively tough, but it can be brittle if struck with a hard object.
Bloodstone has a Mohs hardness of 6.5 to 7, making it suitable for use in jewelry and carvings. It is also thermally stable, which means it can withstand heat without damage. However, it is not resistant to strong acids, which can cause etching on the surface.

Care and Cleaning
Aquamarine: Preserving Clarity and Brilliance
Aquamarine is a relatively hard and durable gemstone, but it can still be damaged by harsh chemicals and physical impacts. To keep aquamarine jewelry looking its best, it is important to follow proper cleaning and maintenance practices.
Aquamarine can be cleaned using a soft cloth and mild soap. A soft-bristled brush can be used to remove dirt and debris from the surface of the stone. It is important to avoid using harsh chemicals, such as ammonia or bleach, as these can damage the surface of the gemstone and reduce its clarity.
Aquamarine should also be stored separately from other gemstones to prevent scratches. It is best to store it in a soft cloth or jewelry box to protect it from dust and physical damage. It is also important to avoid exposing aquamarine to extreme temperatures, as this can cause thermal shock and damage the stone.
Aquamarine is not heat-sensitive, but it should not be exposed to high temperatures for extended periods. It is also not recommended to use steam cleaners or ultrasonic cleaners on aquamarine, as these can cause microfractures and reduce the stone’s clarity.
