Vintage Silver and Enamel Moroccan Berber Ring with Coins

This is a lovely vintage Moroccan ring.  It is likely from Tiznit as the enameling suggests. The face is squared-shaped with what looks like an upward bud at its center.  The enamel is light green and orange and the ring's tip and corners end in silver coin pendants. The ring is in good condition.

• The base measures 2.7 x 2.7 cm (1 1/8 x 1 1/8"). 
• The ring's shank is 9 mm ( 1/4") wide.
• Weight is 25.2 grams.
• Size is 10 1/2 at its middle.
