Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it draws the eye along a graceful arc, evoking subtle drama without excess. This solitaire semi-set invites you to select a 7 x 3.5 mm center stone, its pointed ends enhancing finger length with refined geometry.

Crafted in 18K white gold, the mounting features a low-profile setting designed for everyday ease. The band’s smooth contour and secure prongs ensure comfort and durability, making it a reliable companion from morning coffee to evening plans. Each piece is meticulously finished and inspected in our Williamsburg studio, reflecting a commitment to precision and wearability.

Our diamonds are lab-grown, offering clarity and brilliance with a reduced environmental footprint. This ethical choice aligns with a modern approach to fine jewelry, marrying beauty with responsibility.

The slender silhouette suits hands that appreciate subtle elongation and a sleek profile. Its modest height fits comfortably beneath gloves and pairs effortlessly with stackable bands or wedding rings of varied styles.

Should you need resizing or have questions about setting your chosen stone, our Brooklyn studio team is ready to assist with personalized guidance and care.
