Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of the marquise diamond, casting a delicate dance of light that seems to stretch beyond the finger. This three-stone engagement ring, set in cool platinum, balances architectural elegance with a whisper of romance.

Each marquise center stone measures 9 by 4.5 millimeters, its tapered shape sculpted to elongate the hand gracefully. Flanked by two smaller stones, the trio is nestled in a low-profile setting that hugs the finger comfortably, designed for everyday wear without catching or shifting. The platinum band is hand-finished in Williamsburg, its smooth surface polished to a soft sheen that complements the diamond’s sharp geometry.

Crafted exclusively with lab-grown diamonds, this ring reflects a commitment to ethical sourcing and environmental mindfulness, offering clarity and brilliance without compromise.

Its slender silhouette suits those who appreciate refined statement pieces that layer effortlessly with wedding bands or stackable rings. The comfort fit band ensures a secure yet gentle embrace, ideal for hands of all sizes seeking a blend of modernity and timeless form.

Should you require resizing, our Brooklyn studio offers precise adjustments to ensure your ring fits as naturally as it feels.
