Halo
Lumière Sonnet Halo Princess
The Lumière Sonnet Halo Princess is set with a lab-grown or natural princess-cut diamond of about 2.5 carats, measuring 7.00 × 7.00 mm — its clean geometric corners catching light with architectural precision. Lab-grown stones offer identical optical and physical brilliance to mined diamonds, with full ethical traceability; natural diamonds remain a cherished choice for those who value traditional provenance. A halo of 62 accent diamonds lifts the total weight to approximately 2.93 carats, framing the princess cut in continuous radiance. Crafted in your choice of 14-karat or 18-karat gold, weighing 3.10 g or 3.65 g respectively. An ideal ring for an engagement, a milestone anniversary, or elevated everyday wear. IGI or GIA certified, ethically sourced.
