Lab-Grown Diamond Engagement Ring

Imagine the gentle curve of a marquise diamond catching the soft morning light, its elongated silhouette tracing a delicate arc across your finger. This semi-set solitaire invites you to choose a 6 x 3.5 mm lab-grown marquise, whose pointed ends and graceful shape lend a quiet drama and elongation to the hand.

Crafted in warm 10K rose gold, the slender band is polished to a satin finish that feels smooth and intimate against the skin. The low-profile setting balances security with subtlety, designed for everyday wear without catching or discomfort. Each piece is meticulously finished by hand in our Williamsburg studio, ensuring a refined edge and flawless fit.

Our diamonds are ethically grown, offering clarity and brilliance without the environmental cost of traditional mining. This ring’s gentle rose tone complements the marquise’s vintage-inspired geometry, making it a natural choice for those who appreciate romantic minimalism with a modern conscience.

Its slender silhouette suits slender to medium fingers and layers beautifully with stackable bands or wedding rings. The comfort fit band allows for easy wear under gloves or during daily tasks, making it a versatile companion for life’s moments.

Should you wish to adjust sizing, our in-studio experts offer precise resizing to ensure your ring fits like a second skin. Lead times vary slightly depending on diamond selection but we guide you through every step with care.
