Black Zirconium Ring with 1 ct Lab Created Diamond

One carat of brilliance, held by tension alone. A round brilliant lab-created diamond is suspended between the two ends of a matte black zirconium band, so light reaches the stone from every side and no prongs crowd the view. This is the engagement ring for someone who never wanted the expected one.

Black zirconium begins as a silvery metal. Heated under controlled conditions, its surface transforms into a dense, jet-black oxide that is lightweight, hypoallergenic and highly scratch resistant. The soft satin finish makes the diamond's white fire look even brighter. The band tapers from 6.5 mm to 4.5 mm for a comfortable fit all day.

The center stone is a lab-created diamond: chemically, physically and optically identical to a mined diamond, with the same hardness and the same sparkle, grown without new mining.
