Amazing Story of Aquamarine Gemstone

As the name suggests, it possesses different shades of seawater color, from light aqua to dark blue with tints of green.

How are they formed in Nature?

Aquamarines are created in the presence of two major components: Beryl and iron.

Beryl is comprised of beryllium aluminum cyclosilicate located in deposits known as granitic pegmatite. These pegmatites are large structures composed of interlocking minerals and rocks. Depending upon the impurities, different colors are produced such as yellow, white, red, green, and blue. However, in its purest form, beryl is colorless.

When beryl deposits are cast in the presence of iron, the crystallization process turns them to turquoise or a blue color resulting in the foundation of aquamarine gemstones.

From Where Do Aquamarine Gemstones Come?

They are one of the most brilliant and incredible gems found in many countries around the world – Afghanistan, China, Kenya, Mozambique, Pakistan, Russia, and The United States. However, Brazil is a major supplier and has been declared the aquamarine capital of the world. Each locality produces a different color variation of aquamarine.

Aquamarine through Stages: Rough to Polished Gemstone

Aquamarine completes a long journey from rough stone to a polished gemstone. This process involves countless hours of labor and immense efforts.The mining process starts from investigating the geological site and assessing the environmental impact of the mines that might offer aquamarine gemstone. Then, the identified landform is gently moved with a smooth wavelike motion above the sea level.

This rough stone undergoes the following techniques before transforming into polished gemstones:

Sorting – Stones are segregated based on their size (larger or smaller), color (pale to brilliant), clarity (heavily included or flawless) and cut (the crystalline structure is hexagonal – six sided). The stones that are richly colored are the most desired stones, and the ones with pale coloration are customized into inexpensive jewelry.

Gem Processing – This is one of the critical steps wherein rough stones are transformed into beautiful and attractive gemstones. This process involves a lot of experience, hard work, and potential. The stones are outlined on the slab, and the shapes are cut depending upon their resiliency. Good quality gem should be translucent and clear and not contain any flaw, such as a scratch.

Pre-forming – Few gemstones possess sturdy and rigid crystalline structure and are difficult to cut. However, aquamarine gemstones can be cut to highlight the stone’s natural brilliance. Its hardness ranges from 7.5 – 8 on the Mohs scale, which makes them highly durable and resistant to scratches.
