Lab-Grown Diamond Engagement Ring

Light catches the elongated points of the marquise diamond, casting a subtle, tapered glow that draws the eye along the finger’s natural line. This semi-set solitaire ring features a 7 x 3.5 mm marquise center, designed to balance presence with everyday ease.

Crafted in warm 10K rose gold, the band is shaped for comfort with a low-profile setting that sits close to the skin, minimizing snagging while maximizing wearability. Each piece is hand-finished in our Williamsburg studio, where precise prong placement secures the stone without excess metal, allowing light to flood the facets.

Our lab-grown diamonds offer the clarity and brilliance of mined stones with a lighter environmental footprint, reflecting a commitment to ethical jewelry without compromise.

The slender silhouette suits those who appreciate refined geometry and a ring that layers effortlessly with wedding bands or stackable styles. Its modest scale and comfort fit make it ideal for daily wear, including glove-friendly winter months.

Should you need a different size, resizing is straightforward and handled in-house to preserve the ring’s integrity.
