This 14-karat yellow gold ear wire has two 3mm round faceted Ethiopian opal stones set in 4-prong settings. This Ethiopian opal stone features the signature vivid translucence and play of color typical of high-quality white opal that is comparable to sought-after Australian opal. The front of the earring features twist-wire that adds visual interest. A closed ring makes it easy to add a drop or dangle to create a custom design. If desired, use a rubber ear wire guard (available separately) to keep the finished earring in place on displays and earring cards and as protection for customers against loss. Sometimes called French wires or shepherd's hooks, this classic style is easy to work with and simple to wear—ideal for a variety of designs.
