Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along a graceful arc. This semi-set three-stone engagement ring foundation in warm 14K yellow gold invites your choice of center stone, designed to showcase a 12 x 6 mm marquise with architectural drama and subtle vintage flair.

Handcrafted in our Williamsburg studio, the band features a delicate yet sturdy profile, finished with a smooth comfort fit that rests lightly on the finger. The three-stone setting balances presence with wearability, allowing for daily grace without catching or bulk.

Each piece reflects our commitment to ethical jewelry, crafted exclusively for lab-grown diamonds that offer clarity and brilliance with a reduced environmental footprint.

This ring suits those who appreciate refined geometry and a statement that elongates the hand, ideal for stacking or wearing solo. Its low-profile setting pairs well with gloves and everyday movement, designed for life’s intimate moments.

Should you need resizing, our in-studio artisans ensure a precise fit without compromising the ring’s integrity or finish.
