Lab-Grown Diamond Engagement Ring

Sunlight catches the sharp corners of an 8 x 8 mm Asscher diamond, its step-cut facets revealing a quiet geometry that feels both architectural and intimate. This semi-set three-stone ring foundation in warm 14K rose gold invites your choice of center stone, framed by gently tapered shoulders that balance presence with subtlety.

Handcrafted in our Williamsburg studio, the band’s smooth finish and low-profile setting ensure a comfortable fit for daily wear, while the rose gold’s soft glow complements the diamond’s glassy clarity. Each curve and angle is refined through artisan techniques, inspected meticulously to meet exacting standards.

Choosing a lab-grown diamond here means embracing clarity without compromise—ethical origins paired with sustainable practices, quietly woven into every detail.

The design suits those who appreciate architectural elegance and a ring that layers well with wedding bands or stackable accents. Its modest height slips easily beneath gloves and sleeves, making it a versatile companion for everyday life.

Should you need resizing or wish to discuss stone options, our Brooklyn studio offers personalized guidance with thoughtful timing tailored to your schedule.
