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 foundation in warm 14K yellow gold awaits your choice of center stone, designed to cradle a 6 x 3.5 mm marquise with precision.
Each band is hand-shaped in our Williamsburg studio, the yellow gold polished to a soft gleam that complements the diamond’s fiery sparkle. The three-stone setting balances architectural elegance with everyday wearability, featuring a low-profile design that rests comfortably against the finger without catching.
Crafted with lab-grown diamonds in mind, this ring carries a quiet commitment to sustainability and clarity, reflecting a modern approach to ethical jewelry.
Its slender shank and subtle prongs make it ideal for stacking or wearing solo, especially suited to hands that appreciate refined geometry and a touch of vintage-inspired drama. The semi-set style allows you to select a marquise cut that resonates personally, ensuring a truly custom expression.
Should you need resizing or guidance on selecting the perfect center stone, our Brooklyn studio offers expert advice with a relaxed, pressure-free approach.
