Here at deBebians.com we have perfected the skill and we are proud of the fancy yellow diamond engagement rings we manufacture.  I have had a few clients ask me to manufacture rings without a cup.   These clients are typically seeking a more washed out look.  If the yellow diamond is a GIA certified fancy intense or fancy vivid a cup is not necessarily needed.  Personally, as a jewelry designer, I would still incorporate this into the design of the ring.  18kt yellow gold prongs are always needed in canary diamond engagement ring so that the prongs blend into the diamond.
