Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of the marquise shape, casting a slender, graceful silhouette across the hand. This semi-set halo engagement ring in 14K yellow gold frames an 8 x 4 mm marquise center, designed to amplify the stone’s tapered drama while maintaining a subtle profile.

Crafted with precision, the low-profile halo setting balances sparkle with everyday practicality, ensuring the ring sits comfortably beneath gloves or sleeves. The smooth band curves gently for a comfort fit, making it ideal for daily wear without sacrificing elegance.

Each lab-grown diamond is selected for clarity and brilliance, reflecting a commitment to sustainable, ethical jewelry without compromise. The warm glow of yellow gold complements the marquise’s vintage-inspired shape, creating a piece that feels both modern and enduring.

This design suits those who appreciate architectural refinement with a hint of classic romance, especially flattering on slender fingers or as part of a stack. The semi-set style allows you to choose a center stone that speaks personally, with expert guidance available to ensure a seamless fit.

Resizing is straightforward, handled in-studio with care to preserve the ring’s integrity and finish. Typical lead times accommodate custom requests, reflecting our hands-on approach in Williamsburg.
