Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a 12 x 6 mm marquise diamond, casting a subtle, tapered glow that draws the eye along the finger’s natural line. This semi-set solitaire ring offers a refined foundation in warm 14K yellow gold, designed to cradle your chosen stone with precision and understated elegance.

Crafted in Williamsburg, the band is shaped for comfort with a low-profile setting that sits close to the hand, minimizing snagging and ensuring daily wearability. The smooth finish and balanced weight reflect meticulous hand inspection, a hallmark of our Brooklyn studio’s approach to fine jewelry.

Each ring supports a lab-grown diamond, selected for clarity and brilliance without the environmental cost of traditional mining. This ethical choice aligns with a modern commitment to sustainability and transparency.

The slender band suits those who appreciate a sleek silhouette and pairs effortlessly with stacking rings or a wedding band. Its low profile makes it glove-friendly and ideal for active lifestyles, while the marquise shape adds a distinctive architectural flair.

Should you need resizing, our in-studio experts ensure a precise fit without compromising the ring’s integrity. Typical lead times reflect careful craftsmanship rather than rushed production.
