Lab-Grown Diamond Engagement Ring

Imagine the quiet moment when a heart-shaped diamond catches the light, its soft curves reflecting a modern promise. This semi-set three-stone engagement ring foundation in 18K yellow gold offers a structured yet intimate frame for a 10 x 10 mm center stone, ready to become a personal symbol of connection.

Crafted with precision in Williamsburg, Brooklyn, the band’s clean lines and balanced proportions ensure a low-profile silhouette that sits comfortably for daily wear. The three-stone setting, designed with subtle architectural clarity, allows light to dance freely around the center and side stones once set, enhancing brilliance without excess.

Each ring foundation is finished by hand, inspected meticulously to meet exacting standards before it leaves the studio. The warm glow of 18K yellow gold complements the heart shape’s romantic softness while maintaining a confident, modern-minimal aesthetic.

Ethically sourced lab-grown diamonds bring clarity and sustainability to the design, reflecting a commitment to responsible luxury without compromise.

This ring suits those who appreciate refined structure and understated elegance, especially for hands that favor a balanced, glove-friendly fit. Its semi-set nature invites you to select a center stone that resonates personally, making the design uniquely yours.

Resizing is available to ensure the perfect fit, and our studio welcomes questions about care and customization timelines.
