Lab-Grown Diamond Engagement Ring

Sunlight catches the gentle curve of a round diamond, its facets whispering quiet brilliance across a smooth 18K white gold band. This solitaire semi-set invites you to choose a center stone between 7.3 and 7.7 mm, framing the diamond’s classic fire with a delicate six-prong embrace.

Handcrafted in Williamsburg, the band features a comfort fit profile that rests lightly against the skin, designed for everyday grace without bulk. The six-prong setting balances security with elegance, allowing light to dance freely through the stone’s iconic round cut—known for its lively sparkle and timeless appeal.

Each piece is meticulously finished and inspected in-studio, ensuring a refined surface and seamless polish that complements the diamond’s clarity. Crafted from responsibly sourced 18K white gold, this ring reflects a commitment to ethical jewelry through lab-grown diamond options, reducing environmental impact without compromising beauty.

Ideal for those who appreciate understated sophistication, this solitaire suits slender to medium finger sizes and pairs effortlessly with stacking bands or a wedding ring. Its low-profile setting slips comfortably beneath gloves and daily wear, making it a thoughtful choice for a life in motion.
