Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, luminous shadow that dances across the hand. This semi-set halo engagement ring frames a 6 x 3.5 mm marquise stone with delicate pavé accents, enhancing its graceful taper and vintage-inspired allure.

Crafted from warm 10K yellow gold, the band is polished to a soft glow, offering a comfortable fit that sits low enough for everyday wear without sacrificing presence. The halo setting balances sparkle with subtlety, designed and finished in our Williamsburg studio where each detail is carefully inspected for precision.

Our commitment to sustainability shines through the lab-grown diamond’s clarity and ethical origin, reflecting a modern approach to fine jewelry without compromise.

Ideal for those who appreciate romantic geometry and a ring that complements slender fingers, this design layers beautifully with stackable bands or stands alone as a statement of quiet elegance.

Should you wish to adjust sizing, our Brooklyn studio offers expert resizing to ensure a perfect, lasting fit.
