Lab-Grown Diamond Engagement Ring

Sunlight catches the gently curved facets of a 9 mm round diamond, casting a quiet dance of brilliance that feels both intimate and expansive. This semi-set solitaire ring invites you to choose a center stone that will become the heart of your story.

Crafted from warm 18K yellow gold, the band is polished to a soft glow that complements the diamond’s fire without overwhelming it. Its slender profile and smooth finish ensure a comfortable fit for daily wear, while the classic solitaire setting offers a timeless stage for your chosen gem. Each piece is meticulously hand-finished in our Williamsburg studio, where precision meets subtle artistry.

Our diamonds are lab-grown, reflecting a commitment to ethical sourcing and environmental mindfulness without compromising on clarity or sparkle.

The ring’s low-profile design suits those who appreciate understated elegance and desire a piece that layers effortlessly with wedding bands or stackable rings. Its balanced proportions flatter a variety of hand shapes, making it a versatile choice for everyday grace.

Should you need resizing or guidance on selecting the perfect center stone, our Brooklyn studio offers personalized consultations to ensure your ring fits seamlessly into your life.
