Lab-Grown Diamond Engagement Ring
Imagine the elongated silhouette of a marquise diamond, its pointed ends drawing the eye along the length of your finger with quiet drama. This semi-set foundation in 14K white gold offers a sleek, modern-minimal frame designed to highlight a 12 x 6 mm center stone of your choosing, accented with subtle detailing that balances clarity and structure.
Crafted in Williamsburg, the band’s smooth finish and low-profile setting ensure comfortable daily wear, while the precise prong work secures your stone with refined confidence. The cool white gold complements the marquise’s glassy brilliance without distraction, creating a harmonious stage for your custom gem.
Each piece reflects our commitment to ethical jewelry, featuring lab-grown diamonds that reduce environmental impact without compromising on clarity or fire.
This mounting suits those who appreciate architectural elegance and desire a ring that feels as natural as it looks striking—ideal for stacking or wearing solo with ease. Its streamlined design fits comfortably under gloves and layers well with wedding bands.
Should you need resizing or prefer a consultation on stone selection, our Brooklyn studio offers personalized guidance with no pressure and transparent timelines.
