Lumière Sonnet Halo Round
The Lumière Sonnet Halo Round is set with a lab-grown or natural round-cut diamond of about 0.85 carats — a 6 mm stone that sits at the heart of a delicate halo of 33 accent diamonds, bringing total diamond weight to approximately 1.19 carats. Lab-grown stones offer identical optical brilliance and fire to mined diamonds while reflecting a more conscientious approach to sourcing; 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 2.18 g or 2.56 g respectively, for a refined yet wearable feel. A graceful match for an engagement, an anniversary milestone, or elevated everyday wear. IGI or GIA certified, ethically sourced.
