Lumière Sonnet Hidden Halo Round

Round

9.80 mm· 3.60–4.40 ct total

The Lumière Sonnet Hidden Halo Round is set with a lab-grown or natural round-cut diamond of about 3.35 carats — measuring 9.80 mm across — cradled by a discreet halo of 56 accent diamonds that together bring the total weight to nearly 4 carats. Lab-grown diamonds share the same optical brilliance and chemical composition as mined stones while offering a transparent, ethically considered origin; natural round diamonds remain the classical choice for those who prize traditional provenance. The band is crafted in your choice of 14-karat or 18-karat gold, weighing 3.31 g or 3.90 g respectively, keeping the silhouette refined and wearable for an engagement, a milestone anniversary, or polished everyday elegance. IGI or GIA certified, ethically sourced.
