Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated marquise diamond, its tapered points casting a delicate shadow across the warm 14K yellow gold band. This halo setting cradles the 12 x 6 mm center stone with artisan precision, each tiny pavé diamond hand-set to amplify the marquise’s dramatic silhouette.

Crafted in our Williamsburg studio, the ring’s low-profile design ensures it rests comfortably against the finger, while the smooth finish on the shank offers a subtle, tactile warmth. The halo setting balances brilliance with wearability, making it an elegant choice for daily life.

Our commitment to sustainability shines through the lab-grown diamond’s clarity and ethical origin, reflecting a modern approach to fine jewelry without compromise.

This ring suits those who appreciate architectural elegance with a vintage whisper—its elongated shape visually lengthens the finger, pairing beautifully with stackable bands or worn solo. The comfort fit band and secure setting make it glove-friendly and resilient.

Should you need resizing, our Brooklyn studio offers expert adjustments to ensure a perfect fit without disrupting the ring’s integrity.
