Lab-Grown Diamond Engagement Ring

Imagine the subtle drama of a marquise diamond catching light with every turn of the hand, its elongated silhouette framed by a delicate halo that amplifies brilliance without excess. This semi-set engagement ring foundation in 18K white gold offers a modern-minimalist canvas, crafted with precision to highlight the 6 x 3.5 mm marquise center stone you select.

Each band is hand-finished in Williamsburg, Brooklyn, with a low-profile setting designed for daily wear—comfortably hugging the finger while allowing light to dance across the halo’s fine pavé. The smooth shank balances structure and clarity, ensuring the ring feels as refined as it looks.

Our commitment to ethical jewelry shines through the exclusive use of lab-grown diamonds, combining sustainability with exceptional clarity and sparkle.

The slender silhouette suits those who appreciate architectural elegance and a confident statement that remains understated. Its low profile and smooth edges make it ideal for stacking or pairing with a wedding band, while the marquise shape naturally elongates the finger for a flattering fit.

Should you need resizing or prefer a custom consultation, our Brooklyn studio welcomes you to explore options with no pressure and full transparency on lead times.
