Lab-Grown Diamond Engagement Ring

Sunlight catches the gentle curve of a 3.5 mm round diamond, its facets whispering quiet brilliance against the warmth of 10K yellow gold. This semi-set solitaire invites you to choose a center stone that will become the heart of a ring designed to live intimately with your everyday moments.

Crafted in Williamsburg, Brooklyn, the band’s smooth, low-profile shank balances subtle presence with comfort, its polished finish reflecting the care of hand inspection and expert finishing. The classic round cut offers a lively sparkle, a dance of light that feels both familiar and endlessly captivating.

Each diamond is lab-grown, embodying a commitment to ethical sourcing and environmental mindfulness without compromising on clarity or fire.

Ideal for those who appreciate understated elegance, this solitaire’s slender band fits seamlessly alongside wedding bands or stackable rings, while its modest profile ensures ease of wear, even with gloves or daily tasks.
