A gem setting includes a base structure and a first plurality of supporting prongs extending from the base structure. The first plurality of prongs is arranged with a first lateral extent, each of the prongs forming the first plurality of supporting prongs engaging both a central stone and at least two surrounding stones. The gem setting also includes a second plurality of supporting prongs extending from the base structure. The second plurality of prongs is arranged with a second lateral extent beyond the lateral extent of the first plurality of supporting prongs. The second plurality of supporting prongs is composed of tri-prongs each including a first lateral prong, a second lateral prong and a central prong. The first lateral prong and the second lateral prong are oriented to engage the at least two surrounding stones engaged by the prong of the first plurality of supporting prongs. |
