You’ve doubtless seen a halo ring before, but probably not one like this. The round center stone is surrounded closely by a halo of glittering diamonds. That halo is surrounded by a second halo, which contrasts artistically in shape. This outer halo is a square of diamonds, with its corners slightly higher than the rest, giving it a gentle scallop, and adding some interesting depth to the design. This engagement ring is an artistic modern piece, incorporating a geometric theme.
