These pieces are unique! And beautiful! Genuine white quartz! And black spinel ! In sterling silver! Stamped 925 STS ! Ring is size 8 ! The design reminds me of Angel wings on the sides ! I did purchase these pieces separately at the time and I didn’t want to break up the set . I would say the white quartz is definitely 3 carats or a bit more on each piece . I also found one earring to this set ! I lost the other earring! So the one earring I will include !Good condition!
