American turquoise ring

One-of-a-kind find,  Arizona Castle Dome Turquoise and Red Coral ring.   This wonderfully large flower ring is made of (18) Red Coral petals, surrounding a large colorful Castle Dome Turquoise center, and all set tediously in sterling silver.   I have had it awhile & do not know it’s date of origin, but it has little, if no wear.   Even with it’s large beautiful size, it sits well & is very comfortable to wear.
