Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of an 8 x 4 mm marquise diamond, its tapered points drawing the eye along a graceful arc. This semi-set halo engagement ring foundation in 10K yellow gold invites your choice of center stone, framed by a delicate halo that amplifies light and presence without excess.

Handcrafted in our Williamsburg studio, the band’s warm gold gleams softly against the skin, shaped for comfort and daily wear. The low-profile setting balances elegance with practicality, designed to slip easily beneath gloves or stack alongside complementary bands. Each curve and prong is meticulously finished, ensuring a secure yet refined embrace for your chosen stone.

Our commitment to lab-grown diamonds reflects a thoughtful approach to clarity and sustainability, offering brilliance with a lighter environmental footprint. This ring’s silhouette suits those who appreciate architectural drama paired with artisan subtlety—ideal for hands that favor elongated shapes and a modern, yet intimate, statement.

Should you wish to adjust sizing or explore custom details, our Brooklyn studio welcomes you to a pressure-free consultation, where your vision guides the process. Lead times are transparent, with attentive care throughout every step.
