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 three-stone semi-set ring in 18K rose gold offers a warm, subtle glow that complements the diamond’s dramatic shape without overwhelming it.

Each band is hand-forged in our Williamsburg studio, where the rose gold is carefully polished to a soft sheen. The setting is designed with a low profile to sit comfortably against the finger, allowing daily wear without catching. The three-stone arrangement balances visual impact with understated elegance, framing the center stone’s 7 x 3.5 mm marquise cut—a shape known for elongating the hand and adding a refined, architectural edge.

Our diamonds are lab-grown, ensuring clarity and brilliance while minimizing environmental impact. This ethical choice reflects a commitment to sustainability without compromising on beauty or craftsmanship.

The slender band suits those who appreciate delicate yet distinctive jewelry, ideal for stacking or wearing solo. Its comfort fit and modest height make it glove-friendly and practical for everyday life.

Should you need resizing, our in-house artisans handle adjustments with precision, preserving the integrity of the setting and finish.
