What is Aquamarine?

Aquamarine belongs to the beryl mineral family. Its recognisable blue to blue-green colouring often appears in delicate pendants and rings, where an open setting helps the stone catch light. As with any gem, clarity, cut, treatment disclosures and the actual metal setting must be checked for the individual item.

History and cultural context

The name evokes seawater, and aquamarine has long carried maritime associations in jewellery traditions. Those stories are part of its cultural history rather than evidence of any physical benefit.
