Lab-Grown Diamond Engagement Ring

When sunlight catches the gentle curve of a round diamond, it scatters light like a quiet promise. This semi-set engagement ring offers a delicate stage for a 4.2 to 4.9 mm center stone, inviting you to choose a gem that reflects your unique story.

Crafted in warm 14K rose gold or cool 14K white gold, the slender band features a comfort fit that rests naturally against the skin. The six-prong setting balances security with openness, allowing the diamond’s brilliance to breathe while maintaining a low profile suited for everyday wear. Each ring is meticulously finished and inspected in our Williamsburg studio, where subtle hand polishing ensures a smooth, tactile experience.

Our diamonds are lab-grown, embodying clarity and ethical sourcing without compromise.

This ring suits those who appreciate understated elegance and a design that layers effortlessly with other bands or stands alone with quiet confidence. Its modest height makes it glove-friendly and ideal for hands of all sizes.

Should you need resizing, we handle adjustments with care to preserve the ring’s integrity and finish.
