Meet Adria, so named for the Hebrew word for sea, and which means, strong and noble.A vibrant creature, the life of the party! In her tentacles, she holds a natural 12 carat Australian opal cabochon.Cast in solid sterling silver, this is a piece that has a nice weight to it and she feels substantial in your hand.The stone weight is 12.1 ct. This is a natural gemstone from Australia. It does have some color play, more so to one side than the other.One of a kind, ready to ship!Includes the steel ball chain as pictured.CheersAustin
