Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its pointed ends drawing the eye along the finger with a quiet drama. This semi-set halo ring foundation in 18K white gold offers a delicate frame, ready to cradle a 6 by 3 mm marquise stone with artisan precision.

Handcrafted in our Williamsburg studio, the band is polished to a satiny finish that feels smooth against the skin, designed with a subtle low profile to slip comfortably beneath daily wear. The halo setting, once completed, will amplify the diamond’s natural brilliance, enhancing the marquise’s signature tapered elegance.

Each piece reflects our commitment to ethical jewelry, featuring lab-grown diamonds that balance clarity and sustainability without compromise. The cool white gold complements the stone’s icy fire, creating a refined contrast that suits a modern aesthetic.

Ideal for those who appreciate architectural grace and understated sparkle, this mounting supports a slender finger or pairs beautifully with stackable bands. Its low profile ensures ease with gloves or rings worn alongside.

Resizing is available to ensure a perfect fit, and our typical lead time allows for careful finishing and inspection before delivery.
