Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of an 8 x 4 mm marquise diamond, its tapered points drawing the eye along the finger with subtle drama. This solitaire semi-set in 18K white gold offers a refined foundation, inviting your choice of center stone to become a personal statement.

Crafted with a low-profile bezel setting option, the mounting balances secure wear with everyday ease, its smooth band designed for comfort and glove-friendly fit. The cool white gold gleams softly, finished to a satin polish that resists scratches and complements the diamond’s sharp geometry.

Each piece reflects a commitment to sustainable luxury, featuring lab-grown diamonds that reduce environmental impact without compromising brilliance or clarity.

Ideal for those who appreciate architectural elegance and a streamlined silhouette, this ring suits slender to medium finger shapes and pairs effortlessly with stacking bands or wedding rings of varied styles.

Resizing is available to ensure a precise fit, with typical lead times tailored to your custom design preferences.
