Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of the marquise diamond, casting a slender, graceful shadow across your hand. This solitaire ring, set in warm 14K yellow gold, frames the 10 x 5 mm lab-grown stone with delicate precision, emphasizing its tapered points and brilliant facets.

Handcrafted in our Williamsburg studio, the band is shaped for comfort with a smooth, low-profile setting that sits close to the finger, ideal for everyday wear. The artisan finish reveals subtle hammer marks beneath the polished surface, a quiet signature of Brooklyn craftsmanship. Each ring undergoes meticulous inspection to ensure the prongs secure the diamond without overwhelming its refined geometry.

Our lab-grown marquise diamond offers the clarity and sparkle of mined stones with a significantly reduced environmental footprint, reflecting a commitment to ethical jewelry without compromise.

The slender shape naturally elongates the finger, making it a thoughtful choice for those who appreciate sculptural elegance and a ring that layers effortlessly with wedding bands or stackable pieces. Its low profile also makes it glove-friendly and unobtrusive for daily life.

Should you need a custom fit, resizing is available with care to preserve the ring’s structural integrity and finish.
