Trilogy ring Traversine in white gold with three brilliant-cut diamonds, twenty-four centigrams total

Three brilliants in a row at the center, all of the same size, and four white gold crossbars set vertically that separate them and close the row at both ends. Two small brilliants are set on each crossbar, one above the other: eleven stones in all. The three large ones have no claws around them — they are set between two crossbars, which act as seat and spacer at once. The shank is thin, square in section, and reaches the setting without widening: on the finger the mounting rises little and the row stays short.

Two grams twenty-five of eighteen-carat white gold. The three brilliants at the center come to twenty points of carat in all, the eight on the crossbars another four: twenty-four points, color F-G and clarity VS. It is the Traversine trilogy in its small size — the same count of stones as the middle model, three at the center and eight on the crossbars, with less than half the gold and less than half the carat: what changes is the bulk, not the design. Twenty points divided by three give three stones of under seven points each, and eleven stones on a shank this thin are counted one by one, close up.
