Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along a delicate arc of rose gold. This semi-set solitaire ring invites you to select a center stone that measures 12 by 6 millimeters, a shape known for its dramatic, vintage-inspired flair and ability to visually lengthen the finger.

Crafted from warm 14K rose gold, the band is hand-finished in our Williamsburg studio with a subtle polish that balances softness and resilience. The setting’s low profile ensures the ring sits comfortably beneath gloves or daily wear, while the slender shank offers a graceful frame that complements the diamond’s architectural form. Each piece undergoes meticulous inspection to meet exacting standards of fit and finish.

Our commitment to ethical jewelry is reflected in the exclusive use of lab-grown diamonds, which provide exceptional clarity and brilliance with a reduced environmental footprint.

This design suits those who appreciate artisan craftsmanship and a statement piece that remains wearable every day. Its slender band and low-profile setting make it ideal for stacking or pairing with a wedding band without overwhelming the hand.

Should you wish to adjust sizing or explore center stone options, our Brooklyn studio offers personalized consultations to guide your choices with care and expertise.
