Lab-Grown Diamond Engagement Ring

Sunlight catches the gentle curve of a 3.4 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 a daily companion, framed by a delicately polished band crafted from 10K yellow gold for a soft, familiar glow.

Hand-finished in Williamsburg, the band’s slender profile balances presence with subtlety, designed for comfort and ease beneath a glove or alongside a wedding band. The low-profile setting keeps the diamond close to the hand, making it an ideal choice for those who favor understated elegance without sacrificing sparkle.

Each piece embraces the clarity and sustainability of lab-grown diamonds, reflecting a commitment to ethical jewelry that honors both beauty and conscience.

Perfect for someone who values a classic silhouette with a personal touch, this solitaire foundation adapts seamlessly to various diamond cuts and sizes, offering a versatile canvas for your custom design journey.
