Silpada Ring sz 7, Sterling Silver 925 & Light green, Square Mother of Pearl

Beautiful split Sterling Silver ring by Silpada Designs, with a square, light green Mother of Pearl stone. Marked 925 with the Silpada logo. Retired, from approx 2006. I believe it's a Sz 7. The inside diameter is 17mm. I've polished it, but there is still some bits of tarnish in the grooves & inside. A pro could clean it up even better!
