Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along a refined, architectural line. This semi-set engagement ring foundation in 18K white gold offers a sleek, modern-minimal frame designed to highlight a 10 x 5 mm marquise center stone of your choosing.

Crafted with precision in Williamsburg, Brooklyn, the band’s clean profile and subtle accents provide a structured yet understated stage. The 18K white gold is polished to a soft sheen, balancing durability with a comfortable fit that sits low on the finger—ideal for daily wear and effortless stacking.

Each piece reflects a commitment to ethical sourcing, featuring lab-grown diamonds that deliver clarity and brilliance without compromise. This approach aligns with a sustainable ethos, reducing environmental impact while celebrating refined craftsmanship.

Designed for those who appreciate clarity and confident geometry, the marquise shape elongates the hand with its distinctive pointed ends, while the semi-set style invites you to select a center stone that resonates personally. The ring’s low profile ensures it pairs well with gloves or alongside other bands.

Should resizing be needed, the studio offers expert adjustments to ensure a perfect fit without disrupting the ring’s clean lines. Typical lead times accommodate thoughtful customization without rush.
