Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its pointed ends tracing a delicate arc across the finger. This three-stone engagement ring features a 12 x 6 mm marquise center, flanked by two smaller stones that enhance its dramatic, tapered elegance.

Handcrafted in 14K yellow gold, the band offers a warm glow that complements the diamond’s sharp geometry. The artisan finish reveals subtle hammer marks beneath a polished surface, a testament to careful Brooklyn studio craftsmanship. The setting is low-profile, designed for everyday wear without catching or discomfort, while the three-stone arrangement balances visual impact with refined restraint.

Each diamond is lab-grown, chosen for clarity and brilliance, reflecting a commitment to ethical jewelry that minimizes environmental impact.

Ideal for those who appreciate architectural lines and a statement piece that remains wearable—this ring fits comfortably with a smooth inner shank and pairs beautifully with stacking bands or a wedding band of similar width.

Resizing is available to ensure a precise fit, with typical lead times reflecting our bespoke approach.
