Care: Aquamarine is a relatively durable stone in terms of hardness and should stay beautiful as long as care is taken to prevent scratches and heavy blows to the stone.  Do not expose your aquamarine to intense heat.  Wash with warm soapy water.  Ultrasonic machines are generally safe so long as the stone is not fractured.
