Lab-Grown Diamond Engagement Ring

Sunlight catches the sharp edges of a 6 x 6 mm square diamond, its facets reflecting a quiet geometry that balances strength with refined elegance. This three-stone semi-set ring invites you to choose a center stone that will anchor the design with personal meaning.

Crafted from 18K white gold, the mounting features a low-profile setting that hugs the finger comfortably, while the artisan’s hand-polished finish ensures a subtle gleam without excess flash. The three-stone arrangement offers a harmonious play of light, with side stones enhancing the center’s architectural clarity.

Each lab-grown diamond is selected for its clarity and ethical origin, reflecting a commitment to sustainability without compromise. The cool white gold complements the square shape’s modern geometry, making it an ideal choice for those who appreciate clean lines and contemporary form.

Designed for everyday wear, the ring’s comfort fit and modest height allow it to stack effortlessly with wedding bands or other fine jewelry, while its balanced proportions suit a variety of hand shapes and sizes.

Should you wish to adjust the fit, resizing is available through our Brooklyn studio with care to preserve the ring’s structural integrity. Typical lead times for completion vary but are communicated clearly during the custom design process.
