Unique Art Deco Aquamarine Blue Ring - US size 5/White Gold

Authentic Art Deco ring. Natural stone set in white gold. Was told it was aquamarine by a jeweler but it might actually be Topaz or another stone. However, the stone is a genuine natural stone. US Size 5. Has been cleaned recently. Canadian origins, but otherwise its history is unknown. Would make a great gift. Comes in different box. Feel free to ask questions or send an offer. This was sold to a jewelry reseller who intended to list it with a markup but claimed it was a different stone than aquamarine. Feel free to send offers. It’s already marked below what it cost when it was purchased from an antique jewelry store in Toronto. Would rather have the info out there! It’s still a very pretty ring.
