Hailing from the brilliant landscapes of north-eastern Brazil, Santa Maria aquamarine infatuates with a spectrum of glorious sky-blue tones.
Let’s explore the natural influences producing this gem's magical color diversity.
The Profile of a Phenomenon
First discovered in 1910 in Bahia, Brazil, Santa Maria aquamarine immediately stood out for its limpid blue clarity rivaling fine sapphire. While most aquamarine exhibits a cool cyan hue, Santa Maria glows with vivid primary blue shades ranging from a delicate icy tone to the deepest azure.
From Sky to Sea
Subtle mineral factors present during crystal formation lend Santa Maria aquamarine an extraordinary color intensity with pure blue overtones:
- High sodium content adds marine blue hues
- Low iron mutes greenish tones
Shades of Wonder
Santa Maria color grades include:
- Deep blue. Intense primary blue with slight secondary green/purple
- Medium blue. A rich azure shade lighter than the deep blue
- Light blue. Soft serene sky blue with high clarity
With its color magic mirroring cloudless Brazilian skies, Santa Maria aquamarine promises a cheerful and elegant addition to any gem collection. Our jewelry store in New York City offers a range of Santa Maria aquamarine jewelry, along with other loose gemstone pieces such as rubies, emeralds, and sapphires.

From Earth to Elegance: Mining Locations and Methods
The journey from rough crystal to refined gem requires navigating remote mines across the globe to procure these glimmering blue treasures.
Where These Gems Are Found
The Santa Maria Aquamarine, named after the Santa Maria mine in Itabira, Minas Gerais, Brazil, where it was discovered over a century ago, has additional deposits.
- African nations like Mozambique, Nigeria and Madagascar
- Other Brazilian states such as Bahia and Rio Grande do Norte
How It's Mined
Common mining techniques include:
- Alluvial mining involves filtering through sediment-filled rivers, where crystals accumulate.
- Open-pit surface mining, using heavy machinery, to remove the top layers of gem-rich soil.
- Underground mining, with tunnels bored into the mountains, to access aquamarine veins.
Adhering to sustainable practices has become essential for preserving local ecosystems and securing ethically sourced gems that benefit communities financially.
For aquamarine enthusiasts, balancing ecological well-being with the acquisition of these sparkling treasures continues to be a challenging endeavor.
Beyond the Surface: Chemical Properties and Treatment
The brilliance of Santa Maria aquamarine originates from exceptional chemistry and cutting-edge treatments tailored to accentuate its natural attributes.
Elemental Composition
As a gem-quality beryl, Santa Maria aquamarine has a Be3Al2Si6O18 molecular structure. Color-influencing factors include:
- Traces of iron that lend blue-green tones
- Sodium ions that contribute violet-blue hues
- The absence of manganese prevents dulling yellow tints
Enhancement Methods
Common practices used to improve color and clarity include:
Heat Treatment: Heating to 450°C can enhance the existing blue color and remove yellow tints.
Irradiation: Exposing stones to radiation can darken them, but this often requires subsequent heating.
Fracture Filling: This treatment involves using oils or resins to minimize the visibility of fractures.
Ethical Considerations
Reputable jewelers always disclose all treatments and the potential negative effects on the durability or value of their jewelry. Our jewelry store, vividcarat.com, is one such dealer. We provide accurate information about the gems available in stock.
Supporting responsible mining and treatment practices preserves Santa Maria aquamarine’s legendary radiance for future generations.
