2 Bold Stone Sterling Rings Abalone White Moon Glow SZ 9

Listing is for both rings shown. Measured on my ring sizer they are size 9s. The colorful stone is abalone. I am not sure what the stones are in the white ring. The large stone looks like some sort of mother of pearl or moon glow glass maybe. The smaller stones are faceted so are either glass or crystal. White ring is 1.3" tall. Abalone ring is 7/8" tall.
