Princess cut diamonds are best suited to this type of setting, which demands great skill from the person making it. The biggest perk is that it elevates the apparent size of the stone.     Why the Stone Looks Larger Invisibly set diamonds appear in a seemingly continuous flow, without any interruptions by prongs or bezels. Your first look at it would leave you with the impression of a large diamond, the ring has several smaller ones instead. This lowers the cost considerably, seeing as a smaller stone can always be used for a comparable effect. Other benefits of this setting include enhanced safety for the gem, and boosted shine as a result of so many diamonds being set so closely together, without a visible setting blocking any of the light they exude.
