Black spinel and turquoise multi gem sterling silver pendant necklace

This necklace is in good pre owned condition with the exception of the green chrome diopside stone having a small chip missing. I didn’t even notice it until I started photographing it under magnification. Priced accordingly.  Black spinel faceted 2-3mm beads with a sterling silver clasp. Pendant is also sterling silver featuring a turquoise stone (most likely composite), and a green Russian chrome diopside stone (chipped), and a iolite stone. Necklace measures 20 inches in length.
