The Fulton Prong Set Diamond Eternity Ring – 18K Yellow Gold Band (2 1/2 ct)

An Intricate Diamond Eternity Ring in Warm 18K Yellow Gold

The Fulton is a prong set diamond eternity ring built around a continuous run of round brilliant lab grown diamonds along a slim 18K yellow gold band. Each principal diamond is held in its own prongs and framed by smaller accent stones, so the line reads as one intricate ribbon of light rather than a row of separate settings. The prongs lift every stone off the metal, letting light enter from the sides as well as the top.

It works as an anniversary band, as a stacking ring beside a solitaire, or as a standalone piece for everyday wear. Within our rings collection, it sits at the more detailed, light-heavy end, made for someone who wants a full line of diamonds rather than a single stone.

Prong-Set Round Diamonds on a Slim, Light-Catching Band

The defining choice here is the prong setting. Rather than sinking the stones into the metal, each diamond is raised in prongs that hold it from the edges, which keeps the pavilion open to light and gives the band its bright, animated sparkle. For a ring worn daily, that open setting helps the diamonds stay lively even as the gold takes on the soft warmth of normal wear.

The band averages 2.1 mm, slim enough to sit flush against an engagement ring or to wear alone without crowding the finger. Its 123 round diamonds, 2 1/2 ct in total, are matched along the run so the line stays even from one end to the other.

Solid 18K Yellow Gold and IGI Certified Lab Diamonds

The ring is solid 18K yellow gold, the same alloy through the shank and the gallery, not plating over a base metal. It is set entirely with lab grown diamonds, which are chemically and optically identical to mined diamonds and grown in a controlled lab rather than pulled from the ground. The diamonds are IGI certified, with grading you can keep on file.

• ◆ Each diamond seat is hand-cut into the gold so the stone sits level and secure before the prongs are closed
• ◆ All 123 stones are set individually and the prongs tightened one by one, the slow step that keeps an intricate line stable over years of wear
• ◆ Round diamonds are matched for size, color, and clarity along the run so the row reads as one continuous line
• ◆ Every finished ring is inspected under magnification, prong by prong, before it ships
