Lab-Grown Diamond Engagement Ring

Imagine the subtle elongation of your hand as a marquise diamond, measuring 12 by 6 millimeters, catches the light with its tapered, dramatic silhouette. This semi-set solitaire ring in warm 14K rose gold offers a refined foundation, crafted to cradle your chosen stone securely while maintaining a low profile for everyday grace.

Each band is hand-finished in our Williamsburg studio, polished to a smooth comfort fit that slips on effortlessly and resists catching. The rose gold’s gentle blush complements the marquise’s striking shape, balancing bold geometry with wearable elegance.

Our commitment to sustainability is reflected in the lab-grown diamond clarity this setting is designed to showcase—ethical jewelry that honors both beauty and conscience.

Ideal for those who appreciate a statement piece that remains discreet enough for daily wear, this mounting suits slender to medium finger sizes and pairs well with stacking bands or a simple wedding band. Its low-profile setting ensures glove-friendly comfort and ease of movement.

Should you need resizing or prefer a custom finish, our Brooklyn studio offers personalized consultations to tailor your ring with care and precision.
