Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, luminous beam that seems to stretch beyond the hand. This three-stone semi-set engagement ring in warm 10K yellow gold frames a 12 x 6 mm marquise center with two delicately balanced side stones, creating a quiet harmony of light and shadow.

Crafted with a low-profile setting, the band’s gentle curve rests comfortably against the finger, designed for everyday wear without sacrificing elegance. Each prong is meticulously shaped and polished in our Williamsburg studio, ensuring the diamond’s facets catch the eye from every angle while maintaining a secure hold.

Our commitment to sustainability shines through the lab-grown diamond’s clarity and brilliance, offering an ethical alternative without compromise. The warm yellow gold complements the marquise’s vintage-inspired shape, making it an ideal choice for those who appreciate a blend of classic form and modern conscience.

Its slender profile and balanced three-stone design suit hands that favor refined, stackable rings or a single statement piece that feels both intimate and distinctive. The semi-set allows you to select a center stone that resonates personally, inviting a custom experience tailored to your vision.
