Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of the marquise shape, casting a slender, graceful silhouette that seems to stretch the hand. This semi-set halo engagement ring in 14K yellow gold frames an 8 x 4 mm marquise center stone, ready to be paired with your choice of lab-grown diamond.

The halo setting enhances the center’s brilliance while maintaining a low profile, designed for everyday wear without catching or discomfort. The warm glow of yellow gold complements the stone’s sharp geometry, and the band’s smooth finish ensures a comfortable fit that slides easily beneath gloves or alongside other stackable rings.

Crafted in our Williamsburg studio, each piece undergoes meticulous hand finishing and inspection to balance durability with refined elegance. The semi-set design offers flexibility, allowing you to select a lab-grown diamond that meets your clarity and cut preferences.

Our commitment to ethical jewelry is reflected in the use of sustainable lab-grown diamonds, reducing environmental impact without compromising on sparkle or quality.

This ring suits those who appreciate architectural lines paired with a touch of vintage-inspired detail, ideal for slender fingers or anyone seeking a distinctive yet wearable engagement ring.
