Aquamarine and aqua spinel represent the tranquil essence of March, capturing the shifting light of the season as winter yields to spring. These two gemstones, while distinct in their geological origins and physical properties, share a common visual language of calming blue hues. Aquamarine, a member of the beryl family, has long been celebrated as the traditional modern birthstone for March. It is frequently described as the "treasure of the sea," a name that reflects its deep historical association with maritime culture and its color spectrum, which ranges from the palest sky blue to the deep, clear tones of tropical waters.
In recent years, aqua spinel has emerged as a popular alternative birthstone for the month. While aquamarine remains the most recognized gem for March, aqua spinel offers a vibrant, captivating blue-to-blue-green option that rivals the beauty of its beryl counterpart. It is often lab-created, allowing for exceptional clarity and brilliance that stands out in modern jewelry designs. Both stones are celebrated for their symbolism of tranquility, clarity, and emotional healing, making them meaningful choices for those born in March. Whether featured in a minimalist solitaire ring or an elaborate vintage setting, these gems embody the promise of fresh beginnings and the serene strength of the ocean.
History and Lore
The history of aquamarine is rich with maritime folklore and ancient beliefs. Its name is derived from the Latin words aqua (water) and marina (sea), explicitly linking the gem to the ocean. For centuries, sailors have carried aquamarine as a talisman for good luck and protection against peril on the water. It was believed to be a treasure of mermaids and was thought to ensure a safe voyage. Beyond its nautical significance, aquamarine was also associated with marital happiness and was often given as a gift to promote love and affection.
While aqua spinel is a more modern introduction to the birthstone lexicon, it has quickly garnered a reputation for symbolizing clarity and calm. Unlike aquamarine, which has a lineage stretching back to ancient civilizations, aqua spinel’s history is tied to advancements in gemological synthesis. It is celebrated today for its aesthetic appeal and durability, offering a contemporary alternative for March birthdays. The gem is frequently marketed as a stone that brings peace and promotes emotional healing, aligning it with the same soothing attributes historically assigned to aquamarine.
Geological Formation and Sources
Aquamarine belongs to the beryl mineral family, which also includes emerald and morganite. It forms within igneous rocks, specifically in pegmatites—coarse-grained rocks that allow for the growth of large, well-defined crystals. The blue color of aquamarine is caused by trace amounts of iron within its chemical structure. The presence of iron, and its specific oxidation state, dictates whether the stone exhibits a light sky blue or a deeper, more saturated ocean blue. Major sources of natural aquamarine include Brazil, which is known for producing large, high-quality crystals, as well as Nigeria, Madagascar, and Pakistan.
Aqua spinel is a distinct mineral species. While natural spinel exists, the "aqua spinel" referred to as a March birthstone in the provided materials is specifically lab-created. The sources indicate that James Avery Artisan Jewelry utilizes lab-created aqua spinel in their March collection. This synthetic process allows for the creation of gems that possess vibrant blue-to-blue-green hues and exceptional clarity, often free from the inclusions found in natural stones. Because it is lab-created, aqua spinel is a sustainable and consistent source of high-quality blue gemstone material, making it accessible for a wide range of jewelry designs.
Gemological Properties
Understanding the physical properties of these gemstones is essential for both jewelers and collectors. Their differences in hardness, clarity, and chemical composition dictate how they should be worn, set, and cared for.
Chemical Composition and Hardness
Aquamarine is a beryl with the chemical formula Be₃Al₂(SiO₃)₆. It contains trace iron and sometimes other elements that influence its color. On the Mohs scale of hardness, aquamarine ranks between 7.5 and 8. This makes it a durable gemstone suitable for rings and daily wear, though it can still be scratched by harder materials like diamond or corundum.
Aqua spinel is a synthetic version of the mineral spinel, with the chemical formula MgAl₂O₄. The provided sources do not specify the exact hardness of the lab-created aqua spinel, but natural spinel typically ranks an 8 on the Mohs scale. This places it in a similar durability range to aquamarine, making it an excellent choice for rings that are worn frequently.
Color and Clarity
The primary allure of aquamarine is its color. The gem ranges from a "palest hint of the sky at dawn" to the "deep, clear blue of tropical seas." The most valued colors are typically the more saturated blues, though lighter pastel shades are also popular. Aquamarine is known for its "exceptional clarity," often being eye-clean.
Aqua spinel is described as having "vibrant blue-to-blue-green colors." It is noted for its "brilliance and intensity," which can rival aquamarine. The lab-created nature of this stone often results in very high clarity, contributing to its sparkle and visual appeal in jewelry settings.

Symbolism and Metaphysical Beliefs
Both March birthstones are heavily imbued with symbolic meaning, focusing on emotional balance and protection.
Aquamarine is widely regarded as a stone of courage and emotional healing. It is believed to: * Soothe fears and reduce stress: Its connection to the calming nature of the ocean is thought to wash away anxiety. * Promote clarity of mind: It is often associated with clear communication and the ability to see truth. * Protect travelers: Historically, it was a talisman for sailors, and modern believers still use it for protection during travel, particularly over water.
Aqua Spinel, while newer to the metaphysical scene, shares many of these associations: * Symbol of clarity and calm: The sources explicitly state that it is drawn for its symbolism of these traits. * Renewal: Like aquamarine, its blue color connects it to the themes of fresh starts and the transition from winter to spring. * Emotional Healing: It is believed to promote peace and help process emotional blockages.
For those born in March, choosing between these two stones often comes down to personal preference: the historical gravitas of aquamarine versus the vibrant, modern appeal of aqua spinel.
Jewelry and Design Applications
The aesthetic versatility of both stones has led to their widespread use in various jewelry styles.
Aquamarine is frequently set in: * Solitaire Rings: Highlighting the stone's natural clarity and color. * Vintage Designs: Often framed with milgrain details to evoke a sense of history. * Halo Settings: Where smaller diamonds surround the aquamarine to amplify its soft glow. * East-West Orientations: A modern trend where the stone is set horizontally to showcase its shape.
Aqua Spinel is popular in: * Single-Gemstone Pieces: Such as necklaces and bracelets where its "luminous" quality can shine. * Mixed-Metal Designs: The gem's vibrancy pairs well with various metals, from sterling silver to rose gold. * Heirloom-Quality Gifts: Given its durability and beauty, it is often chosen for milestone jewelry intended to be passed down.
Care and Cleaning
Proper maintenance ensures these gemstones retain their beauty. Due to their durability, both are relatively easy to care for, but precautions are necessary.
- Hardness: With a hardness of 7.5 to 8, aquamarine and aqua spinel can withstand daily wear but should be stored separately from diamonds and other harder stones to prevent scratching.
- Cleaning: Both gems can be safely cleaned using warm water, a drop of mild dish soap, and a soft toothbrush. Ultrasonic cleaners are generally safe for aquamarine and lab-created aqua spinel, but steam cleaning is not recommended as sudden temperature changes can cause fractures, particularly in stones with inclusions.
- Storage: Store each piece in a soft cloth pouch or a separate compartment in a jewelry box to prevent abrasion.
