This domed mixed metal style features a tantalum exterior and a precious metal rounded interior in your choice of 18K white gold or 14K rose gold. Tantalum is a dense hypoallergenic metal that doesn’t corrode with everyday use making it the perfect choice for a wedding ring. To properly care for a tantalum ring read our Jewelry Care Guide. The white gold version of this design features no rhodium plating allowing a warm hue to shine through.
