Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along a graceful arc. This semi-set three-stone ring in warm 14K rose gold frames a 9 x 4.5 mm marquise center with two delicate side stones, each carefully positioned to enhance the center’s dramatic sparkle.

Handcrafted in our Williamsburg studio, the band is shaped for comfort with a subtle taper that feels natural on the finger. The low-profile setting keeps the stones secure yet unobtrusive, making it a refined choice for daily wear. Each prong is meticulously finished to cradle the marquise’s sharp points without compromising durability.

Our diamonds are lab-grown, offering the clarity and fire of mined stones with a smaller environmental footprint. This ethical approach aligns with a modern commitment to sustainability without sacrificing brilliance.

The slender rose gold band complements a variety of hand shapes, especially elongating shorter fingers with its vertical emphasis. Its modest height and smooth edges make it glove-friendly and ideal for stacking alongside wedding bands or delicate bracelets.

Should you need a custom fit, resizing is available to ensure the ring sits perfectly. Typical lead times reflect our artisan process and attention to detail.
