1930s Art Deco 1.15ct European Cut Diamond Ring, Platinum (in the online store)

This is one of the nicest minimally designed Deco rings I’ve come across.  You’d expect simple rings to be easier to get right, but I find it’s often the opposite.  It’s all about proportions, and if it’s not perfect the whole thing looks off.  This one has perfect proportions I think, and the way the diamonds taper away to the sides, seems to emphasize the  size of the center.
