You’ve got to hand it to JCK’s readers: They know a good ring when they see it.  For the third straight year, that style has nabbed top honors in our retailer-voted Jewelers’ Choice Awards. In 2014, it was a sweet morganite cocktail ring by Yael Designs. In 2015, a luminous Lightning Ridge opal ring from Omi Privé.
