Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated curve of an oval diamond, casting a gentle glow that seems to stretch beyond the stone itself. This semi-set solitaire ring invites you to select a 9 x 7 mm oval center, its shape known for elongating the finger with quiet elegance.

Crafted in a fixed two-tone combination of 18k yellow and 18k yellow and platinum and 18k yellow and platinum, the band balances warmth and coolness with a modern-minimal silhouette. The six-prong setting secures the stone while maintaining a lightweight, low-profile feel that slips comfortably beneath daily wear. Each ring is meticulously finished and inspected in our Williamsburg studio, ensuring a refined surface and structural integrity.

Choosing a lab-grown diamond here reflects a commitment to ethical jewelry, reducing environmental impact without compromising brilliance or clarity.

Designed for those who appreciate clarity and structure, this solitaire suits hands that favor a sleek, confident statement. Its low profile and slender band make it ideal for stacking or wearing alongside a wedding band, while the comfort fit ensures ease throughout the day.
