Which country aquamarine is best?

Aquamarine, a stunning gemstone known for its captivating blue to blue-green hues, has been cherished for centuries for its beauty and perceived mystical properties. Named after the Latin words for “water” and “sea,” this gemstone’s tranquil color evokes the serene waters of the ocean. Among the various sources of aquamarine around the world, Brazil stands out as the premier source, renowned for producing some of the finest quality stones. However, Madagascar has also emerged as a significant player in the aquamarine market, contributing its unique characteristics to the gemstone’s allure. This article delves into the qualities that make Brazilian and Malagasy aquamarine highly prized, exploring their geological origins, mining processes, and market significance.


The Geological Origins of Aquamarine

Aquamarine belongs to the beryl family, which includes other notable gemstones such as emerald and morganite. The vibrant blue color of aquamarine is due to the presence of iron ions within the crystal structure. The depth and quality of the blue can vary significantly, influenced by the iron concentration and the geological conditions under which the gemstone formed.


Brazil: A Geological Treasure Trove

Brazil’s geological landscape is rich and diverse, creating the perfect conditions for the formation of high-quality aquamarine. The country’s aquamarine deposits are primarily found in the states of Minas Gerais, Bahia, and Espirito Santo. Minas Gerais, in particular, is famed for its extensive and high-yielding gem mines. The pegmatite veins in this region are rich in beryl, giving rise to large and clear aquamarine crystals. The geological stability and mineral-rich environment contribute to the formation of aquamarines with exceptional clarity and color saturation.

Madagascar: An Emerging Gemstone Haven

Madagascar’s geological environment is equally fascinating, with a landscape that has yielded numerous precious and semi-precious stones. The island’s aquamarine deposits are primarily located in the regions of Antsirabe and the central highlands. The geological conditions here, characterized by granitic pegmatites and metamorphic rocks, provide a suitable environment for the formation of aquamarine. Malagasy aquamarine is known for its unique and diverse color range, often displaying a vivid blue-green hue that sets it apart from its Brazilian counterparts.

Mining and Extraction Processes

The methods of mining and extraction play a crucial role in determining the quality and market value of aquamarine. Both Brazil and Madagascar employ techniques that aim to preserve the integrity of the gemstones while ensuring sustainable and ethical practices.

Brazilian Mining Techniques

In Brazil, aquamarine is primarily mined through both open-pit and underground mining methods. The country has a well-established mining industry with a focus on ethical and environmentally friendly practices. The miners use sophisticated tools and machinery to extract the gemstones carefully, minimizing damage and ensuring that the natural beauty of the aquamarine is preserved. In regions like Minas Gerais, family-owned mines have been passed down through generations, maintaining traditional mining methods while integrating modern technology to enhance efficiency and yield.

Malagasy Mining Practices

Madagascar’s mining industry, while less developed than Brazil’s, has made significant strides in recent years. Artisanal and small-scale mining is prevalent, with local miners often using manual techniques to extract aquamarine from the earth. These methods, although labor-intensive, are less invasive and help maintain the environmental integrity of the mining sites. Efforts are being made to regulate the mining practices and improve the working conditions for the miners, ensuring that the extraction processes are sustainable and ethical.

Quality and Characteristics of Aquamarine

The quality of aquamarine is assessed based on several factors, including color, clarity, cut, and carat weight. Both Brazilian and Malagasy aquamarine possess distinctive characteristics that make them highly sought after in the gemstone market.

Brazilian Aquamarine: Superior Clarity and Color

Brazilian aquamarine is renowned for its exceptional clarity and vibrant blue color. The gemstones from this region often exhibit a pure blue hue with minimal green undertones, which is highly prized in the market. The clarity of Brazilian aquamarine is also noteworthy, with many stones being eye-clean and free from visible inclusions. This combination of color and clarity makes Brazilian aquamarine ideal for high-end jewelry and investment purposes.

Malagasy Aquamarine: Unique and Diverse

Malagasy aquamarine, on the other hand, is celebrated for its unique color range, which can vary from light blue to deep blue-green. This diversity in hue adds to the gemstone’s appeal, offering a distinct alternative to the classic blue of Brazilian aquamarine. While Malagasy aquamarine may sometimes have more visible inclusions compared to Brazilian stones, these natural imperfections are often considered part of the gem’s charm, adding character and uniqueness.

Market Significance and Demand

The global demand for aquamarine has been steadily increasing, driven by its aesthetic appeal and the growing trend towards colored gemstones in jewelry. Both Brazil and Madagascar play significant roles in meeting this demand, each contributing their unique qualities to the market.

Brazil: Dominating the Aquamarine Market

Brazil has long been a dominant force in the global aquamarine market. The country’s consistent production of high-quality gemstones has established it as a reliable and reputable source. Brazilian aquamarine is highly sought after by jewelers and collectors worldwide, with major auction houses frequently featuring Brazilian stones in their high-profile sales. The reputation of Brazilian aquamarine for its superior quality ensures that it commands premium prices in the market.

Madagascar: A Rising Star

Madagascar has emerged as a significant source of aquamarine in recent years, gaining recognition for the distinctive qualities of its gemstones. The unique color variations and the story of artisanal mining practices add to the allure of Malagasy aquamarine. As the global market becomes more appreciative of diverse and ethically sourced gemstones, Madagascar’s role in the aquamarine market is expected to grow. Efforts to improve mining practices and promote sustainable development in the region will further enhance the marketability of Malagasy aquamarine.

Ethical and Sustainable Practices

In the modern gemstone market, ethical sourcing and sustainability have become critical considerations for consumers and industry stakeholders. Both Brazil and Madagascar are making strides in ensuring that their aquamarine mining practices adhere to these principles.

Ethical Mining in Brazil

Brazil has implemented various regulations and initiatives to promote ethical mining practices. The country’s gemstone mining industry is subject to strict environmental and labor laws designed to protect the natural environment and the rights of workers. Many Brazilian mining companies are also involved in community development projects, providing support and infrastructure to local communities. These efforts ensure that the mining of aquamarine in Brazil not only produces high-quality gemstones but also contributes positively to the society and environment.

Sustainability Efforts in Madagascar

In Madagascar, the focus on sustainability is gaining momentum. The government, along with various non-governmental organizations, is working to formalize the artisanal mining sector and improve the livelihoods of the miners. Initiatives aimed at educating miners about sustainable practices and providing them with the necessary tools and resources are being implemented. These efforts are crucial in ensuring that the extraction of aquamarine does not lead to environmental degradation or exploitation of workers. By promoting responsible mining, Madagascar aims to build a sustainable gemstone industry that benefits both the local communities and the global market.


Aquamarine, with its mesmerizing blue hues and rich historical significance, continues to captivate gem enthusiasts and collectors worldwide. Brazil’s reputation as the premier source of aquamarine is well-deserved, thanks to its consistently high-quality gemstones and ethical mining practices. Meanwhile, Madagascar is making its mark with uniquely colored aquamarine and a commitment to sustainable development. As the global market evolves, the contributions of both Brazil and Madagascar will play a crucial role in shaping the future of aquamarine, ensuring that this beautiful gemstone remains a cherished and valued part of the jewelry industry.
