Lab-Grown Diamond Engagement Ring

Sunlight catches the delicate curve of a round diamond, its facets whispering quiet brilliance against the soft glow of 18k yellow and 18k yellow and platinum and the cool gleam of 18k yellow and platinum. This semi-set engagement ring offers a refined foundation, designed to cradle a 5.0–5.3 mm center stone with a low-profile, five-prong setting that balances security and light play.

Handcrafted in Williamsburg, Brooklyn, the band’s comfort fit contours gently to the finger, while the fixed two-tone design—warm 18k yellow and 18k yellow and platinum shank contrasted by 18k yellow and platinum prongs—creates subtle visual depth. Each ring is meticulously finished and inspected to ensure a smooth, everyday wear experience that complements stacking or solo elegance.

Our commitment to ethical jewelry shines through the use of lab-grown diamonds, offering clarity and sustainability without compromise. The round shape’s classic brilliance suits a variety of hand sizes, elongating the finger with its balanced symmetry and lively sparkle.
