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 foundation in warm 10K yellow gold awaits your choice of a 12 x 6 mm center stone, ready to frame its unique brilliance with a delicate halo of smaller gems.

Handcrafted in our Williamsburg studio, the band is carefully shaped for a comfortable fit, its low-profile setting designed to sit close to the finger without sacrificing sparkle. Each prong and bezel is meticulously finished to ensure durability and everyday wearability, reflecting the artisan workshop’s commitment to precision.

Our lab-grown diamonds offer a clarity and fire that rival mined stones, created with a lighter environmental footprint and a transparent origin story.

This ring suits those who appreciate a statement silhouette balanced by subtlety—its halo enhances the marquise’s dramatic shape while the yellow gold band warms the overall effect. The semi-set design invites you to select a center stone that resonates personally, making it a truly custom expression.

Should you need resizing or guidance on stone selection, our Brooklyn studio offers personalized consultations to ensure your ring fits perfectly and reflects your vision.
