Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a delicate dance of light that feels both intimate and expansive. This three-stone semi-set engagement ring in 18K rose gold frames a 10 x 5 mm marquise center, its pointed ends drawing the eye along the finger with subtle drama.

Handcrafted in Williamsburg, the band’s gentle curve and low-profile setting ensure a comfortable fit for daily wear. Each prong is meticulously finished to cradle the stone securely while allowing maximum light to enhance the marquise’s signature brilliance. The rose gold’s warm glow complements the diamond’s crisp edges, creating a harmonious balance between softness and structure.

Our commitment to ethical jewelry is reflected in the lab-grown diamond’s clarity and sustainability, offering a responsible choice without compromise. The semi-set design invites you to select a center stone that resonates personally, making this ring uniquely yours.

Ideal for those who appreciate a refined silhouette with a romantic edge, this ring pairs beautifully with slender bands or stands alone as a statement of enduring affection. Its low profile and smooth finish make it glove-friendly and perfect for an active lifestyle.
