Sophisticated NWOT cubic zirconia dome ring

Sophisticated CZ dome ring. Quality costume jewelry; R.S. covenant is fashion jewelry crafter. NWT. Marked RSC. Gorgeous, catches the eye w/ stones & dome design. Black stone throughout (I don't know exactly what it is - it looks like onyx to me). Silver plated. Marked Size 7. It feels like 7.5 to me, as I usually wear 7, and this is a bit big on my ring fingers.
