Nine Aquamarine Gemstone Facts (March Stones)
Nine Aquamarine Gemstone Facts
1. Aquamarine’s name comes from the Latin “aqua marina,” meaning “sea water.”
The name was used by the ancient Romans to describe the gemstone’s distinctive blue to blue-green colour, which resembles clear ocean water. This descriptive origin reflects how strongly the gem’s appearance has influenced its identity throughout history.
2. Aquamarine is a blue variety of the mineral beryl.
Beryl is a mineral species that also includes emerald (green), morganite (pink), and heliodor (yellow). Aquamarine gets its blue colour primarily from trace amounts of iron within the crystal structure, distinguishing it chemically from other members of the beryl family.
3. The largest aquamarine ever found weighed over 240 pounds.
Exceptionally large aquamarine crystals have been recovered from pegmatite deposits, particularly in Brazil. Some crystals have measured several feet in length, demonstrating how beryl can form under ideal geological conditions with abundant space and slow cooling.
4. Aquamarines are primarily mined in Brazil, Nigeria, and Madagascar.
Brazil has historically been one of the most important sources, especially the state of Minas Gerais. Significant deposits are also found in parts of Africa and Asia, including Mozambique and Pakistan, where geological environments are suitable for pegmatite formation.
5. Heated aquamarines often become a more intense blue.
Many aquamarines on the market have been gently heat treated to reduce greenish tones and enhance their pure blue colour. This treatment is stable and widely accepted in the gem trade, as it replicates natural heating processes that can occur underground.
6. Aquamarines often have excellent clarity.
Compared to emerald, another beryl variety known for inclusions, aquamarine is typically much cleaner to the naked eye. High clarity makes it especially suitable for larger faceted stones, as light can pass through with minimal interruption.
7. Famous aquamarines have been worn by royalty and displayed in museums.
Large and notable aquamarines are featured in prominent gem collections, including those of major museums and private royal collections. Their size, clarity, and colour have made them popular choices for statement jewellery pieces and important ceremonial items.
8. Aquamarine crystals commonly form in hexagonal shapes.
As a member of the hexagonal crystal system, aquamarine often grows in six-sided prismatic columns with flat terminations. These well-formed crystals are highly valued by mineral collectors as well as gem cutters.
9. Aquamarine ranks 7.5 to 8 on the Mohs hardness scale.
This level of hardness makes aquamarine relatively durable for everyday jewellery use. While it is resistant to scratching from many common materials, it can still be damaged by harder substances such as corundum or diamond.
