Description
This exquisite engagement ring features an emerald cut diamond surrounded by a black ceramic halo and accented with grey diamonds. It was created for a client from Anchorage, AK, who had a clear idea of what she wanted but was having a hard time finding someone who could make it for her. We worked with her to come up with a design that incorporated all of the elements she wanted, and this elegant piece is the result of that collaboration.

Center Diamond
The diamond that sits atop this ring is a 1.40 carat emerald cut stone that the client provided. She really wanted a design that would highlight the stone, with a setting that was as minimal as possible while still being structurally sound. We went with a prong setting which holds the diamond securely, but is still open enough to allow the beauty of the stone to shine through from all angles. Diamond Engagement Rings
Accent Diamonds
Directly below the center of the main stone on each of the ring fronts is a bezel set grey diamond. These add a bit of sparkle to the ring when it’s viewed from the side, and they also add a delicate, classy touch to the design, and tie in a grey shade, which was what the client was going for from the beginning.
Ceramic Halo
In between the main diamond and they grey accent stones is a black ceramic halo that creates a stunning contrast with the sparkling white of the larger diamond. It has a smooth, polished finish, and it was achieved by dipping the piece in a plating solution to coat the metal.
When this client came to us, she was trying to find a way to get a ring made with this diamond but with a dark grey band. Although this wasn’t really an option, we went over various possibilities with her until we hit on this black halo idea. She fell in love with it, and it really turned into a one-of-a-kind piece.
