Gemological overview

Technical and gemological information about this gemstone variety.

Gemological profile

Aquamarine is a blue to blue-green variety of beryl, appreciated for its clear, fresh coloration and natural transparency. Within the beryl family, it is valued for its calm visual character and refined appearance, particularly in well-cut stones with even color distribution.
Chemically composed of beryllium aluminum silicate (Be₃Al₂Si₆O₁₈), aquamarine crystallizes in the hexagonal crystal system and belongs to the silicate mineral group. In gem-quality specimens, it typically displays a vitreous luster and high transparency.
The refractive index of aquamarine generally ranges from 1.577 to 1.583, contributing to a subtle, elegant brilliance rather than strong dispersion. Aquamarine is found in several regions worldwide, with typical sources including Brazil, Madagascar, Mozambique, Nigeria, and Pakistan, each known for slightly different tonal qualities.

Treatments & authenticity

With a hardness of 7.5 to 8 on the Mohs scale, aquamarine offers good durability suitable for everyday jewelry when properly set and worn with standard care. It performs reliably across a wide range of jewelry designs, including rings, pendants, earrings, and bracelets.
While aquamarine is generally resistant to everyday wear, larger stones or more exposed settings benefit from protective designs to reduce the risk of impact. Its combination of durability, clarity, and naturally soothing color makes aquamarine a versatile choice for both everyday jewelry and elegant, understated statement pieces.
