Lab-Grown Diamond Engagement Ring

Imagine the subtle elongation of a marquise diamond catching light with every turn of the hand—its 8 x 4 mm silhouette poised between boldness and grace. This semi-set halo ring foundation in 18K white gold offers a refined stage for your chosen center stone, framed by a delicate halo that enhances brilliance without adding bulk.

Crafted for everyday wear, the low-profile setting keeps the ring close to the finger, minimizing snagging while maintaining a confident presence. The smooth, comfort-fit band balances durability with ease, shaped to sit naturally beneath gloves or alongside stackable bands.

Each piece is meticulously finished in our Williamsburg studio, where precision meets quiet strength in every curve and prong. The 18K white gold’s cool sheen complements the marquise’s architectural form, creating a harmonious interplay of light and shadow.

Our commitment to lab-grown diamonds ensures clarity and ethical sourcing, reflecting a modern approach to fine jewelry that respects both craftsmanship and the environment.

This semi-set ring invites you to select a marquise center stone that resonates with your vision, with resizing available to ensure a perfect fit. Lead times are tailored to your custom design process, allowing thoughtful collaboration without rush.
