A stone this rich doesn't need much else going on. The Starburst Agate Studs pair a polished black agate centre with a gold-plated brass starburst setting, so the stone does the talking and the metal just frames it. Butterfly backs keep them secure and easy to wear all day.
Wear them for the days you want a little more depth without going bold. They sit well against dark tones and pair easily with plainer hoops elsewhere in the ear. A considered finishing touch that doesn't try too hard.
