Lab-Grown Diamond Engagement Ring

When light catches the gentle curves of a heart-shaped diamond, it reveals a quiet declaration of love—intimate and unmistakable. This semi-set solitaire ring invites you to choose a 10 x 10 mm heart-cut center stone, its soft silhouette poised to rest gracefully atop an 18K yellow gold band.

Handcrafted in our Williamsburg studio, the band is shaped for comfort with a subtle taper that balances presence and wearability. The low-profile setting secures your chosen diamond with delicate prongs, allowing maximum light to dance through the stone’s facets while maintaining everyday practicality. Each ring is meticulously finished by hand, ensuring smooth edges and a polished surface that feels as natural as the promise it represents.

Our commitment to lab-grown diamonds means your ring carries the clarity and brilliance of natural gems, with a fraction of the environmental impact. This ethical choice aligns with a modern approach to love and craftsmanship.

Designed for those who appreciate artisan detail and meaningful form, this solitaire suits a hand that favors elegance without excess. Its slender band pairs effortlessly with wedding bands or stackable rings, while the heart shape adds a personal, symbolic touch.
