This antique art deco diamond engagement ring features a 2.21 old European cut diamond. The center diamond is held in place by four prongs which allows for a full view of the stone. The basket is attached to a split shank that provides a gorgeous geometric design. The center stone is accented by four (4) single cut diamonds on each side. An additional marquis cut diamond is bezel set into the shoulder for an extra bit of flash. A truly magnificent art deco engagement ring!
