"She feels vintage and modern at the same time. A definite statement piece!"

Black Onyx Boyfriend Signet Ring
This Black Onyx Boyfriend Signet Ring features a black onyx set in 14k gold. Designed after creating a larger white diamond version for our very own Hotdad, this right hand ring can be worn with a variety of our stacking bands or on her own as a statement piece. We recommend sizing up a quarter size due to the width of this design. Not sure about your size? Order a ring sizer tool!
Available in 18k gold and platinum. Contact us for pricing.
