Like the Santa Maria, other aquamarines are often named for the places where they were mined, but beware of the term Brazilian Aquamarine, because some jewelry sold with that name is actually made with blue topaz. A gemstone called Siam Aquamarine is more than likely a blue zircon that's been heat-treated to intensify its color.If you are unsure if an aquamarine is genuine, ask for clarification.
