This 14-karat white gold trellis-style ring mounting features three basket settings—two side mountings that each hold one .25-ct. (4mm, approx.) round faceted stone and one center mounting that holds one .50-ct. (5mm, approx.) round faceted stone. The shank splits into three sections, with the center section on each side forming one of the prongs on the side mounting. Basket settings feature open sides designed to allow more light to reach and move through the stone, enhancing its brightness and brilliance. Cut a seat in the prongs to accommodate your stone, then burnish the prongs over the stone to secure it in place.
