Round Lab-Grown Diamond Twin-Prong Solitaire Engagement Ring

Twin prongs. Eight slim fingers in four pairs instead of four thick ones, gripping the lab-grown diamond at the same points but with half the visual weight in each.

The reason to want this over a standard head is coverage: two thin prongs hold more securely than one thick prong of the same total metal, and they read as a detail rather than as hardware. That matters most at the top of the range, which is where this ring lives, carrying up to a full carat and a half.

As a gift it lands as a solitaire, which is to say it lands. The twin-prong detail is the part she notices on day three. We size it before it ships, to you or to her, and we can time it to a date.

Big centers put real load on prong tips. We would rather say that than let you find out. Six-month checks, re-tipping under the lifetime warranty, and platinum is the metal we would put a 1.50 carat on if you asked us privately.

Four metals, four center weights, all set and sized to order.
