There can be something wonderful when fine jewellery borrows so heavily from costume jewellery that the two are invisibly commingled. This Black Raven ring by Holly Dyment has a cartoonish look and feel that belies its fine jewellery components. It is made of 18k yellow gold, enamel, diamonds and rubies. But it has the cheerful and fun look of a gum ball machine toy. Just goes to show that gravitas is not a necessary component for fine jewelry pieces.

This sells for USD $9275 at Stanley Korshak.
