This article delves into the properties, history, and symbolism of these two March birthstones, exploring their geological formation, cultural importance, and practical uses in jewelry. By examining the sources and lore surrounding aquamarine and bloodstone, we uncover the enduring appeal of these gems and their place in both historical and contemporary gemology.
History and Lore
Aquamarine
Aquamarine, named from the Latin aqua marina, meaning "sea water," has a long and storied history that dates back to ancient times. Its calming blue color has long been associated with the ocean, and ancient mariners believed that the gemstone would protect them during sea voyages. According to historical accounts, aquamarine was thought to calm the waves and ensure safe passage, making it a favored talisman for sailors.
In addition to its maritime associations, aquamarine has also been linked to matters of the heart and mind. Ancient beliefs held that the gemstone could bring happiness in marriage and was a powerful ally in legal disputes. The gem was said to make the wearer unconquerable and amiable, as well as quicken the intellect. These properties made it a prized possession among warriors and scholars alike.
The gem’s symbolic meanings have endured through the centuries, and it remains a popular choice for jewelry today. In modern times, aquamarine is not only the birthstone for March but also a traditional gift for the 19th wedding anniversary. It is said to enhance the happiness of marriages and symbolize the purity of the soul.
Bloodstone
Bloodstone, also known as heliotrope, carries a rich and somewhat darker history that is deeply rooted in religious and mythological traditions. The gemstone is a form of chalcedony, a cryptocrystalline variety of quartz, and is characterized by its dark green base with flecks of red iron oxide. These red spots are often interpreted as drops of blood, giving the stone its name and its association with vitality and strength.
One of the most famous legends surrounding bloodstone is its supposed connection to the crucifixion of Christ. According to the story, when Roman soldiers pierced Christ’s side with a spear, drops of his blood fell onto the ground, which was composed of dark green jasper. These drops of blood then infused the jasper, creating the first bloodstones. This legend has contributed to the stone’s use in religious carvings and its association with spiritual strength and protection.
Bloodstone has also been valued for its supposed healing properties. It was believed to enhance the circulatory system and bring vitality to the body. Warriors were said to carry bloodstone amulets to protect themselves in battle and to heal their wounds. The stone was also thought to promote courage and decisiveness, making it a popular choice among leaders and adventurers.
Geological Formation and Sources
Aquamarine
Aquamarine is a variety of the mineral beryl, which is composed of beryllium, aluminum, silicon, and oxygen. The blue color of aquamarine is due to the presence of iron within the crystal structure. Naturally occurring deep blue aquamarines are particularly rare, and as a result, they are highly prized in the gemstone market. The most valuable aquamarines are those that display a vibrant, medium blue to slightly greenish blue hue.
Aquamarine is typically found in pegmatite deposits, which are igneous rocks that form from the slow cooling of magma. These deposits are often rich in minerals and provide ideal conditions for the formation of large, well-formed crystals. Brazil has long been the primary source of aquamarine, with the state of Minas Gerais being particularly renowned for its deposits. The region has produced some of the most famous aquamarines in history, including the 1,298-carat stone gifted to Eleanor Roosevelt in 1936 and the Dom Pedro Aquamarine, the largest faceted aquamarine in the world.
Other notable sources of aquamarine include Colombia, the Ural Mountains of Russia, Madagascar, and India. In the United States, aquamarine can also be found in states such as Colorado, Maine, and North Carolina. These deposits, though not as prolific as those in Brazil, still yield high-quality stones that are sought after by collectors and jewelers.
Bloodstone
Bloodstone is a form of chalcedony, a cryptocrystalline variety of quartz. It is composed of microscopic quartz crystals that are tightly packed together, giving the stone a smooth and uniform texture. The dark green color of bloodstone is due to the presence of chlorite or other green minerals, while the red flecks are caused by iron oxide. These characteristics give bloodstone its distinctive appearance and make it easily identifiable among other gemstones.
Bloodstone is typically found in metamorphic and sedimentary rocks, where it forms in veins or as pebbles in riverbeds. The best sources of bloodstone include India, Brazil, and Australia. These countries have been known to produce high-quality stones that are used in a variety of applications, from jewelry to carvings and sculptures.
In India, bloodstone has been mined for centuries and has played an important role in the country’s gemstone industry. The stone is also used in traditional Indian medicine and is believed to have healing properties that promote vitality and strength. In Brazil, bloodstone is often found in association with other quartz varieties, and it is sometimes used in combination with other stones to create intricate jewelry designs.
Gemological Properties
Aquamarine
Aquamarine is known for its clarity and transparency, which make it a popular choice for faceted jewelry. The gemstone typically has a hardness of 7.5 to 8 on the Mohs scale, making it relatively durable and suitable for everyday wear. Its refractive index ranges from 1.56 to 1.60, which contributes to its brilliant sparkle and light dispersion.
One of the most distinctive properties of aquamarine is its color, which can vary from light blue to deep blue-green. The most valuable stones are those that display a medium to deep blue color, as these are the rarest and most sought after. Aquamarine is also known for its large crystal sizes, with some specimens weighing several pounds. This characteristic has made it a favorite among collectors and museum curators, as large, well-formed aquamarines are both visually striking and scientifically interesting.
In terms of clarity, aquamarine is generally free from inclusions, which makes it highly desirable in the gemstone market. Some stones may contain liquid inclusions, but these are usually minimal and do not detract from the gem’s overall appearance. The absence of inclusions also makes aquamarine an ideal candidate for faceting, as it can be cut into a variety of shapes and styles.
Bloodstone
Bloodstone has a hardness of 6.5 to 7 on the Mohs scale, making it slightly less durable than aquamarine but still suitable for use in jewelry. Its refractive index ranges from 1.53 to 1.54, which is typical for quartz-based gemstones. Unlike aquamarine, bloodstone is typically cut as a cabochon rather than a faceted gemstone, as its cryptocrystalline structure does not display the same level of brilliance as faceted stones.
The most distinctive feature of bloodstone is its dark green color with red flecks of iron oxide. These flecks are often arranged in a pattern that resembles drops of blood, giving the stone its name and its symbolic significance. Bloodstone is also known for its ability to absorb and hold color, which makes it an excellent material for dyeing and enhancing its natural colors.
In terms of clarity, bloodstone is generally opaque and does not display the same level of transparency as aquamarine. However, its smooth texture and uniform color make it an attractive choice for carvings and sculptures. The stone is often used in religious and symbolic carvings, where its distinctive appearance is used to convey spiritual or protective meanings.

Care and Cleaning
Aquamarine
Aquamarine is a relatively durable gemstone, but it should still be handled with care to prevent damage. The gemstone has a hardness of 7.5 to 8 on the Mohs scale, which makes it suitable for everyday wear, but it can still be scratched or chipped if exposed to hard objects or rough surfaces. It is important to store aquamarine jewelry separately from other gemstones to avoid scratches and to clean it regularly to maintain its luster.
To clean aquamarine, it is recommended to use a mild detergent and warm water. A soft cloth or a gentle brush can be used to remove dirt and debris, and the gemstone should be rinsed thoroughly and dried with a soft cloth. It is important to avoid using harsh chemicals or ultrasonic cleaners, as these can damage the gemstone’s surface or cause discoloration.
Aquamarine is also sensitive to heat, so it is best to avoid exposing it to high temperatures. If the gemstone is being set or repaired, it is important to use low-heat settings to prevent thermal shock or color changes. Aquamarine can also be affected by exposure to sunlight for extended periods, so it is best to store it in a cool, dark place when not in use.
Bloodstone
Bloodstone is slightly less durable than aquamarine, with a hardness of 6.5 to 7 on the Mohs scale. While it is suitable for everyday wear, it is more prone to scratches and chips if not handled properly.
