Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender beam that seems to stretch beyond the hand. This semi-set engagement ring foundation invites your choice of a 6 x 3.5 mm marquise center, framed by four delicately placed side stones that echo its graceful taper.

Crafted from cool 18K white gold, the band is polished to a soft sheen that complements the diamond’s sharp geometry without overwhelming it. The low-profile setting ensures a comfortable fit beneath gloves or daily wear, while the subtle curve of the shank balances the pointed elegance of the marquise shape.

Each piece is carefully finished in our Williamsburg studio, where precision meets quiet artistry. The semi-set design offers flexibility, allowing you to select a lab-grown diamond that meets your clarity and color preferences, reflecting our commitment to ethical jewelry that honors both beauty and sustainability.

This ring suits those who appreciate refined drama—a hand that welcomes elongation and sparkle without excess. Its slender form layers effortlessly with other bands or stands alone as a statement of quiet confidence.

Should you need resizing or guidance on stone selection, our Brooklyn studio team is ready to assist with thoughtful care and expert advice.
