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 engagement ring foundation in warm 14K yellow gold invites your choice of a 6 x 3 mm marquise center stone, ready to be framed by a delicate halo that amplifies its vintage-inspired drama.

Handcrafted in our Williamsburg studio, the band is shaped for comfort with a subtle curve that rests naturally against the finger, while the halo setting is designed low enough to slip easily beneath gloves or stack alongside other bands. Each piece undergoes meticulous finishing and inspection to ensure smooth edges and a refined polish that catches light without catching on daily wear.

Our commitment to lab-grown diamonds means your ring carries the clarity and brilliance of natural stones with a smaller environmental footprint, reflecting a modern approach to ethical jewelry.

This ring suits those who appreciate architectural elegance with a touch of old-world charm, especially flattering on slender fingers where the marquise shape elongates the hand. The semi-set design offers flexibility to select a center stone that matches your personal vision.

Resizing is available to ensure a perfect fit, crafted with care to maintain the integrity of the setting and band.
