Formation & geological history

Formed in granitic pegmatites and metamorphic rocks like schists during volcanic activity. Rubies typically form in marble or basaltic environments.

Uses & applications

Primary use is in high-end jewelry as faceted gemstones; often gifted for March (Aquamarine) and July (Ruby) birthdays.

Geological facts

Aquamarine belongs to the same family as Emerald (Beryl). Historically, sailors believed aquamarine would protect them at sea. Rubies are the hardest natural gemstone after diamonds.

Field identification & locations

Identify by its clarity, specific 'sea-water' blue hue, and lack of inclusions compared to glass. Found in Brazil, Pakistan, and Madagascar.
