Lab-Grown Diamond Engagement Ring

Sunlight catches the sharp edges of a square diamond, its precise geometry casting a quiet, architectural glow across the hand. This semi-set solitaire invites a fixed two-tone a 4.5 x 4.5 mm square center stone, a shape that balances modern clarity with a subtle, confident presence.

Crafted in a fixed two-tone band of 18k yellow and 18k yellow and platinum and 18k yellow and platinum, the ring’s contrasting metals frame the diamond with warmth and cool strength. The low-profile setting ensures the band sits comfortably for daily wear, while the smooth finish reflects the meticulous handwork of our Williamsburg studio artisans.

Each diamond is lab-grown, offering a clarity and brilliance born from sustainable practices that honor both the earth and your values.

Designed for those who appreciate clean lines and understated elegance, this solitaire complements slender fingers and pairs effortlessly with stacking bands. Its modest height makes it glove-friendly and ideal for an active lifestyle.

Should you need resizing, our in-house team adjusts the band with care, ensuring a seamless fit without compromising the two-tone design.
