Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, dramatic shadow across the hand. This semi-set solitaire invites you to choose a center stone that balances bold geometry with delicate refinement.

Crafted from 14K yellow gold, the mounting features a slender band with a subtle taper that elevates the marquise shape without overpowering it. The prongs are designed to cradle an 8 x 4 mm stone securely while maintaining a low profile for everyday wear. Each piece is hand-finished in our Williamsburg studio, where artisans inspect every curve and angle to ensure seamless comfort and lasting durability.

Our commitment to ethical jewelry shines through the option to pair this setting with a lab-grown diamond, offering clarity and brilliance with a lighter environmental footprint.

The slender band suits those who appreciate a refined silhouette that complements slender or average finger shapes, while the solitaire style stands elegantly alone or layered with stacking bands. Its low-profile setting fits comfortably under gloves and daily wear.

Should you need resizing, our in-studio team handles adjustments with care to maintain the ring’s balance and integrity.
