Abalone bangle bracelet with gem stone ring

This abalone shell bracelet came from Hawaii I’ve had it probably close to 30 years. It’s fits right on the wrist 7 inches long. 1 inch wide at the top and the sides are 1/2 inch. Along with the set comes a Synthetic light purple Hues colored stone ring. I believe it’s size 7 and or 7 and a half it was given to me as a gift both in mint condition. Thank you for looking at my jewelry box
