Coral has always been a favorite of mine but it’s not so plentiful. Red coral grows like a tree, mostly in the Mediterranean Ocean, at least it is the best quality. When it has been over-harvested, larger pieces aren’t easy to purchase as they are shaped from the trunks of the coral, and not the little branches. This ring is handcrafted in sterling silver with a touch of 18KY gold on the sides. I like the horizontal placement as it adds interest and makes it more unique. the coral measures 10mm wide x 14mm long. Size 5. One of a Kind.
