History and Lore
Aquamarine: The Sailor’s Stone
The name aquamarine derives from the Latin aqua marina, meaning “seawater,” a fitting description for its cool blue-green color. The gemstone has long been associated with the sea and maritime safety. Ancient Greeks believed that aquamarine was a gift from the gods, particularly from Poseidon, the god of the sea. Sailors and mariners would carry aquamarine stones with them to ensure calm waters and safe passage, believing that the stone could soothe tempests and ward off the wrath of the sea.
Aquamarine was also revered in ancient Rome, where it was believed to bring happiness in marriage. Some sources suggest that the gem was thought to protect the wearer from danger and promote amiable relationships. Beryl, the mineral family to which aquamarine belongs, was also associated with intellectual clarity and courage in battle, further reinforcing its status as a protective and empowering gem.
In more modern times, aquamarine has become a popular choice for jewelry, especially for those who value its association with serenity and tranquility. It is the 19th wedding anniversary gem, symbolizing a harmonious and enduring union. Its calming color is said to reflect the peace of the Caribbean seas, making it a fitting symbol for a lasting marriage.
Bloodstone: The Stone of Life
Bloodstone, also known as heliotrope, is a form of chalcedony, a type of cryptocrystalline quartz. Its name comes from its characteristic appearance: a dark green matrix flecked with red spots that resemble drops of blood. These red spots are iron oxide inclusions, which give the stone its distinctive look. One of the most enduring legends about bloodstone is that it formed during the crucifixion of Christ, when drops of His blood fell upon the earth and mixed with the green jasper at the foot of the cross.
In medieval Europe, bloodstone was believed to have powerful medicinal and protective properties. It was used in the making of amulets and talismans to ward off illness and to strengthen the body. Bloodstone was also used in religious carvings, particularly in Renaissance-era Europe, where it was favored for depicting scenes of Christ’s crucifixion. The red inclusions were used to represent the blood of Christ, adding a symbolic depth to the stone.
In addition to its religious associations, bloodstone was believed to enhance courage and determination. It was worn by warriors and knights to instill bravery and to protect them in battle. The stone was also used in healing practices, with healers believing it could purify the blood and improve circulation.
The dual symbolism of life and death in bloodstone made it a popular stone among various cultures. In India, for instance, it was considered a powerful stone for promoting vitality and strength. In Europe, it was used in both decorative and medicinal applications, further cementing its place in the cultural imagination.
Geological Formation and Sources
Aquamarine
Aquamarine is a variety of beryl, a mineral composed of beryllium, aluminum, silicon, and oxygen. Its blue-green color is due to the presence of iron in the crystal structure. Beryl typically forms in igneous rock formations, particularly in granite pegmatites, where it can grow into large, well-formed crystals.
The most significant source of aquamarine is Brazil, which produces the finest and most valuable specimens. The state of Minas Gerais, in particular, is known for its high-quality aquamarine deposits. Other notable sources include the Ural Mountains in Russia, Madagascar, Colombia, and parts of the United States, including Colorado, Maine, and North Carolina.
Aquamarine is relatively hard, with a rating of 7.5 to 8 on the Mohs scale, making it durable enough for use in jewelry. It is also known for its clarity and transparency, often appearing as clear as water. This quality, combined with its beautiful color, makes it a popular choice for rings, pendants, and earrings.
Bloodstone
Bloodstone is a type of chalcedony, a cryptocrystalline form of quartz. It is composed of fine-grained quartz and chalcedony, with the red inclusions consisting of iron oxide. These inclusions give the stone its distinctive appearance and are responsible for much of its symbolism and value.
Bloodstone is typically found in sedimentary rock formations, where it occurs as pebbles in riverbeds or embedded in other types of rock. The best commercial sources of bloodstone are India, Brazil, and Australia. India, in particular, is known for producing high-quality bloodstone with well-defined red inclusions.
Bloodstone has a hardness of 6.5 to 7 on the Mohs scale, which makes it suitable for use in jewelry, especially when cut as a cabochon. It is often used in rings, pendants, and other types of jewelry that do not require faceting. Its durability and rich color make it a popular choice for both ornamental and functional pieces.

Gemological Properties
Aquamarine
Aquamarine is a member of the beryl family, which includes emerald, heliodor, and morganite. Its color can range from pale blue to deep blue-green, with the most valuable stones being those with a rich, even blue hue. The presence of iron in the crystal lattice is responsible for this coloration. Unlike emerald, which contains inclusions that are often visible to the naked eye, aquamarine is typically clean and transparent.
Aquamarine has a refractive index between 1.57 and 1.58, which contributes to its brilliance and clarity. It is also known for its pleochroism, a property that allows it to appear different in color depending on the angle from which it is viewed. This can make the stone appear green, blue, or even colorless, depending on the light source and the orientation of the crystal.
The gem is relatively hard, with a rating of 7.5 to 8 on the Mohs scale, making it suitable for use in a variety of jewelry settings. It is also resistant to scratches and abrasions, which enhances its longevity in everyday wear. Aquamarine is typically free from cleavage, which means it is less prone to breaking under stress.
Bloodstone
Bloodstone is a form of chalcedony, which is a type of quartz that forms in fine-grained masses rather than distinct crystals. It is composed of silicon dioxide (SiO₂) with iron oxide inclusions that give it its distinctive red flecks. These inclusions are responsible for the stone’s name and much of its symbolism.
Bloodstone has a hardness of 6.5 to 7 on the Mohs scale, which makes it relatively durable but not as hard as aquamarine. It is often cut as a cabochon to enhance its color and to reduce the risk of damage from wear. The dark green base of the stone provides a striking contrast to the red inclusions, making it an attractive and eye-catching gemstone.
Bloodstone is also known for its ability to absorb and retain oils and other substances, which can affect its appearance over time. This property requires careful cleaning and maintenance to preserve its luster and clarity. Unlike aquamarine, bloodstone is not typically faceted, as its inclusions and texture make it more suitable for smooth, polished surfaces.
Symbolism and Metaphysical Beliefs
Aquamarine
Aquamarine is often associated with calmness, clarity, and emotional balance. In ancient times, it was believed to protect sailors and travelers, ensuring safe passage and warding off danger. This protective quality has been extended to modern interpretations, where aquamarine is thought to promote serenity and to help the wearer maintain composure in stressful situations.
The stone is also associated with communication and truth. It is believed to enhance the ability to speak clearly and confidently, making it a popular choice for those who work in public speaking, teaching, or any profession that requires verbal communication. In some cultures, aquamarine is considered a stone of youth, vitality, and longevity, reinforcing its connection to health and well-being.
Aquamarine is also linked to the throat and heart chakras, which are associated with self-expression and emotional balance. It is believed to help the wearer express their emotions more freely and to foster compassion and understanding in relationships. These metaphysical properties have made aquamarine a popular stone in both jewelry and alternative healing practices.
Bloodstone
Bloodstone is often associated with vitality, courage, and purification. Its name and appearance suggest a connection to the circulatory system, and it has been used in various cultures to promote physical and emotional health. In ancient times, it was believed to purify the blood and to enhance the body’s ability to heal from injury or illness.
The stone is also linked to the root and solar plexus chakras, which are associated with grounding, stability, and personal power. It is believed to help the wearer stay centered and focused, especially during times of stress or uncertainty. Bloodstone is also thought to enhance courage and determination, making it a powerful stone for those who need to face challenges or make difficult decisions.
In addition to its physical and emotional properties, bloodstone is also associated with protection and spiritual clarity. It is believed to shield the wearer from negative energies and to help them connect with their higher self. This makes it a valuable stone for meditation and spiritual practices.
Care and Cleaning
Aquamarine
Aquamarine is relatively easy to care for due to its high hardness and resistance to scratches. It can be cleaned using mild soap and warm water, with a soft brush to remove any dirt or debris. It is also safe to use an ultrasonic cleaner, which can help restore its luster and clarity.
Because aquamarine is free from cleavage and inclusions, it is less prone to damage from impact or pressure. However, it should still be handled with care to avoid any unnecessary wear or breakage. Aquamarine is also sensitive to sudden temperature changes, so it should be stored away from direct heat sources or extreme cold.
When not in use, aquamarine should be stored in a soft pouch or a lined jewelry box to prevent scratches from other gemstones or metals. It is also advisable to avoid exposing aquamarine to harsh chemicals or abrasive cleaners, as these can dull its surface and affect its appearance.
Bloodstone
Bloodstone requires a bit more care than aquamarine due to its lower hardness and its ability to absorb oils and other substances. It should be cleaned using mild soap and warm water, with a soft cloth or brush to gently remove any dirt or debris. It is not recommended to use an ultrasonic cleaner, as the vibrations may damage the stone or cause the inclusions to shift.
Bloodstone should also be stored separately from other gemstones to prevent scratches and abrasions. It is best to store it in a soft pouch or a lined jewelry box to protect its surface. Because bloodstone can absorb oils and lotions, it is advisable to remove it before applying any cosmetics or perfumes.
Bloodstone is also sensitive to high heat, so it should be kept away from direct sunlight or heat sources. Prolonged exposure to heat can cause the red inclusions to fade or the green base to become dull. To maintain its luster and color, bloodstone should be polished with a soft cloth and stored in a cool, dry place.
