Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, luminous shadow that feels like a whispered promise. This semi-set engagement ring invites you to choose a 7 x 3.5 mm marquise center, its tapered points drawing the eye along a delicate arc of four accompanying stones, each carefully positioned to enhance the centerpiece’s graceful drama.

Crafted in warm 14K rose gold, the band is polished to a soft glow that complements the diamond’s fiery brilliance. The five-stone setting balances romantic elegance with everyday wearability, featuring a low-profile design that rests comfortably against the finger without catching. Each prong is meticulously finished by hand in our Williamsburg studio, ensuring a secure yet refined hold that highlights the stone’s unique shape.

Our diamonds are lab-grown, offering clarity and sparkle with a lighter environmental footprint—an ethical choice that aligns with mindful luxury.

This ring suits those who appreciate subtle sophistication and a silhouette that elongates the hand, ideal for stacking with slim bands or worn solo as a statement of quiet confidence. Its comfort fit and low profile make it glove-friendly and perfect for daily wear.
