Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along a graceful arc. This semi-set halo ring in 18K yellow gold frames a 9 x 4.5 mm marquise center, designed to balance striking presence with everyday ease.

Crafted with a low-profile halo setting, the band sits close to the finger, minimizing snagging while maximizing sparkle. The warm glow of 18K yellow gold complements the diamond’s fiery brilliance, finished with a comfort fit that feels natural for daily wear. Each piece is meticulously inspected in our Williamsburg studio to ensure precision and durability.

Our diamonds are lab-grown, offering clarity and fire without the environmental cost of traditional mining.

The elongated marquise shape visually lengthens the finger, ideal for those seeking a distinctive yet elegant statement. Its semi-set design invites you to select a center stone that reflects your personal story, while the halo enhances size and light play without bulk.

Resizing is available to ensure a perfect fit, with care instructions tailored to preserve the gold’s luster and the diamond’s brilliance over time.
