Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a slender, luminous silhouette that draws the eye along the finger’s natural line. This semi-set halo engagement ring foundation in 18K white gold offers a refined stage for a 7 x 3.5 mm marquise center, its sharp geometry softened by a delicate halo that amplifies brilliance without excess.

Crafted with precision in Williamsburg, the band’s low-profile setting ensures comfort for daily wear, while the cool white gold finish is polished to a subtle sheen that complements the diamond’s icy fire. Each curve and prong is meticulously inspected to balance security with elegance, creating a modern-minimalist frame that feels both structured and confident.

Choosing a lab-grown diamond here reflects a commitment to ethical jewelry—minimizing environmental impact while delivering exceptional clarity and sparkle.

The slender shape suits hands that appreciate architectural detail and elongation, pairing effortlessly with stacking bands or worn solo. Its low profile slips easily under gloves or sleeves, making it a practical choice for everyday life.

Should you need resizing, our Brooklyn studio offers expert adjustments to ensure a perfect fit without compromising the ring’s integrity.
