Lab-Grown Diamond Engagement Ring

Imagine the subtle elongation of your hand as a marquise diamond, measuring 7 by 3.5 millimeters, catches the light with its tapered brilliance. This semi-set engagement ring offers a refined foundation, ready to showcase a center stone that balances architectural poise with modern clarity.

Crafted in warm 18K yellow gold, the mounting features delicate accent settings that enhance the diamond’s sharp silhouette without overwhelming it. The band’s smooth finish and low-profile design ensure comfortable daily wear, while the precise prong work secures the stone with quiet confidence.

Each piece is thoughtfully created in our Williamsburg studio, reflecting a commitment to lab-grown diamonds that combine ethical clarity with sustainable practice. This ring’s streamlined form suits those who appreciate minimalist structure and a confident, contemporary aesthetic.

Its slender band pairs effortlessly with stacking rings or stands alone as a statement of subtle sophistication. The semi-set design allows for personalized selection of your ideal marquise diamond, ensuring a perfect match for your style and hand shape.

Resizing is available to ensure a tailored fit, and our Brooklyn studio welcomes you to explore custom options in person or through our online design experience.
