Marcus and Co is another one of those names that I know means I should expect to see great jewelry. This ring is no exception.

Art Deco diamonds and emeralds are a common combination, but this is a really spectacular example. The openwork panel of diamonds and emeralds, centering around a large, emerald-cut diamond, is a really spectacular shape and fairly unique, as far as I’ve seen.
