10ct Elongated Emerald-Cut Diamond Dome Ring with 138ct of Diamonds

A white-diamond dome ring built around a 10-carat elongated emerald-cut center. The dome is paved edge to edge with emerald-cut and baguette diamonds set in an invisible-style grid, so the whole surface reads as one sheet of light, with the center stone standing a step above it. The diamonds total 138 carats.

Elongated emerald cuts are the hardest proportion to find in a large white stone; most rough yields a squarer outline. The step cuts around it are matched for color so the center does not pick up a tint from its neighbors.

We held this ring in New York's Diamond District on October 23, 2026. It is from the personal collection of Joe G. Pacetti and is not offered for sale except upon inquiry through us.
