Silver Ring Alexandrite Sz 8 Cubic Zirconia Designer Rhinestone

Where to start? Truth of the matter is I don't recall if they are sterling or not so I'm calling it silver plate.  I t does not stick to a magnet but it could just be very heave silver plate. There are no markings anywhere on the ring. It's a solid band of high polished silver plate with a small 6mm cubic zirconia either side. A larger 7mm Alexandrite cubic in center. I picked them up many years ago in Tucson so the old brain doesn't remember everything anymore. There's nice scroll work on either side. Stones are crisp and prong set. Sz 8. Nice piece. Never worn. Great cocktail piece.
