SOLID STERLING SILVER 925 cubic zirconia WTS 20 grams ring sz 12.5

I am not familiar with the maker, but this is one solid ring. 20 grams!  Men's band ring with deep cut top sides that are very lightly oxidized.  Above the stone the sterling is indented by design. The round heat set stone tests as cubic zirconia.   Preowned and in good to very good condition. Stamped 925 and WTS inside.

acid tests positive for sterling.
