Although aquamarine comes in many colours, the most prized is a rich, clear, watery blue. Fairly large and clear aquamarines with good colour are among the more valuable semi-precious gems. They are often given step cuts, also known as “emerald” cuts, much like aquamarine’s mineral sister, emerald. Good clarity is important in these stones, especially lighter ones where flaws will be more visible. Brazil is the primary source of aquamarine, although it is mined in other places as well.

Aquamarine has long been a positive stone according to legend, bringing with it health, hopefulness and youth. It was traditionally a favorite of sailors, and is said to be a good choice for anyone who loves the sea. It could also bring love and affection if worn properly. Its supernatural powers were remarkable; legend has it that a person with an aquamarine in his or her mouth could summon the devil and get questions answered.

Aquamarine is March’s birthstone.
