Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a slender, confident silhouette across the hand. This three-stone semi-set ring in 14K white gold frames a 10 x 5 mm marquise center with two delicate side stones, balancing architectural clarity with modern minimalism.

Each band is meticulously crafted in Williamsburg, Brooklyn, with a low-profile setting that rests comfortably against the skin, designed for everyday wear without sacrificing elegance. The polished white gold shank offers subtle brilliance, while the prong setting secures the stones with precision, allowing light to animate every facet.

Our commitment to sustainability is reflected in the choice of a lab-grown diamond, offering exceptional clarity and ethical provenance without compromise.

The elongated marquise shape naturally elongates the finger, making it an ideal choice for those who appreciate structured geometry and refined confidence. Its three-stone design invites stacking or pairing with a wedding band, while the comfort fit ensures it remains a seamless part of daily life.

Should you need resizing, our Brooklyn studio provides expert adjustments to ensure a perfect fit without delay.
