Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of the marquise shape, casting a subtle, tapered sparkle that draws the eye along the finger’s natural line. This semi-set halo engagement ring in 14K yellow gold offers a refined foundation for an 8 x 4 mm lab-grown marquise diamond, designed to balance presence with everyday ease.

The halo setting frames the center stone with a delicate circle of pavé diamonds, enhancing brilliance while maintaining a low profile that slips comfortably beneath gloves or sleeves. Crafted in Williamsburg, Brooklyn, the band’s smooth finish and precise prong work ensure durability without bulk, ideal for daily wear.

Each lab-grown diamond is chosen for clarity and ethical sourcing, reflecting a commitment to sustainability without compromise on radiance. The warm yellow gold complements the marquise’s vintage-inspired silhouette, creating a piece that feels both modern and personal.

Its slender band and secure setting suit hands that appreciate subtle drama and refined geometry, while the semi-set design invites customization with a center stone of your choice. Resizing is available to ensure a tailored fit, crafted with care in our Brooklyn studio.
