Lab-Grown Diamond Engagement Ring

When light catches the gentle curves of a 7 x 7 mm heart-shaped diamond, it reveals a quiet intimacy—an emblem of affection rendered in precise geometry. This semi-set solitaire ring offers a refined foundation, crafted from 18K white gold, designed to cradle your chosen stone with a low-profile bezel that sits close to the finger for everyday ease.

The band’s smooth finish and subtle taper ensure a comfort fit that moves naturally with your hand, while the minimalist setting reduces snagging, making it ideal for daily wear. Each piece is meticulously inspected in our Williamsburg studio, where expert jewelers balance durability with delicate craftsmanship.

Our commitment to lab-grown diamonds means your ring carries a clarity and brilliance born from sustainable innovation, reflecting a modern approach to ethical jewelry without compromise.

With its modest height and streamlined silhouette, this mounting suits those who favor understated elegance and seek a ring that layers effortlessly with wedding bands or stackable styles. The heart shape’s soft symmetry complements a variety of hand shapes, adding a personal touch without overwhelming.

Should you need resizing, our Brooklyn studio offers precise adjustments to ensure your ring fits comfortably for years to come.
