Lab-Grown Diamond Engagement Ring

Light catches the elongated points of a 12 x 6 mm marquise diamond, casting a slender, graceful silhouette that draws the eye along the finger. This semi-set engagement ring offers a refined foundation, ready to showcase your chosen center stone with modern-minimal accents that emphasize clarity and architectural balance.

Crafted from warm 18K yellow gold, the mounting features a clean, structured profile with secure prongs designed for daily wear. The band’s smooth finish and subtle taper ensure comfort without sacrificing presence, while the low-profile setting keeps the ring glove-friendly and stackable alongside complementary bands.

Each piece is meticulously hand-finished in our Williamsburg studio, where precision meets quiet confidence. The lab-grown diamond option reflects a commitment to ethical jewelry, reducing environmental impact without compromising brilliance or clarity.

Ideal for those who appreciate streamlined design with a confident edge, this ring suits slender to medium finger sizes, enhancing the hand’s natural length. The semi-set style invites personal choice, allowing you to select a marquise diamond that resonates with your vision.

Resizing is available to ensure a perfect fit, and our team is happy to guide you through care and customization options during your visit or online consultation.
