Cognac Diamond Pavé Engagement Ring in 14K Brown Gold

This is the only engagement ring on earth set in 14K brown gold — our signature alloy, developed specifically for cognac diamonds. A .52ct natural cognac diamond sits in a four-prong solitaire above a 1.5mm pavé band, and the metal and stone fuse into one continuous warm amber tone. Handcrafted in Queens, NYC.

The stone

The center stone is a natural cognac diamond, graded between C4 and C6 on the Argyle color scale — the deep amber-orange range where cognac diamonds show their characteristic internal fire. Cognac diamonds are formed by nitrogen and natural radiation deep in the earth over billions of years; the color is permanent, untreated, and entirely natural. No two stones are alike, and the .52ct round brilliant we set in this ring is chosen by hand for clarity, cut quality, and saturation. Pavé accents along the shoulders echo the center stone's color and pull warm light across the band.

The setting

A classic four-prong solitaire raises the cognac diamond off the finger, while the 1.5mm ultra thin pavé band keeps the silhouette delicate and modern. The band is the slimmest we offer — designed to disappear against the finger so the stone reads larger and the pavé sparkle wraps your hand. Stacks effortlessly with a matching wedding band.

The metal

This ring is offered in five metals: our signature 14K brown gold, 14K yellow gold, 14K rose gold, 14K white gold, and platinum. 14K brown gold is the Brownstone Collection's defining alloy — an earthy amber-brown that sits between yellow and rose gold, designed specifically so that cognac diamonds and metal merge into one continuous warm tone instead of contrasting. It is the only metal in the world developed for cognac diamonds. All gold options are solid 14K throughout, nickel-free, and never plated or gold-filled.
