This 14-karat yellow gold ear wire is prong-set with two faceted stones, vertically linked—one 3mm round emerald and one 5 x 3mm oval Ethiopian opal. 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. A closed perpendicular ring makes it easy to add a drop or dangle for 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.
