Celeste Trio Side Stone Round

Round

9.99 mm· 3.48–4.26 ct total

The Celeste Trio Side Stone Round is set with a lab-grown or natural round-brilliant diamond of approximately 3 carats — measuring 9.99 mm — whose classical 57-facet brilliance has been the engagement standard for over a century. Lab-grown stones offer identical optical fire and chemical composition to mined diamonds with verified ethical sourcing; natural rounds remain the timeless classical choice for those who value traditional provenance. Three accent side stones flank the centre, lifting the total carat weight to approximately 3.87 ct. Crafted in your choice of 14-karat or 18-karat gold — 3.57 g or 4.20 g respectively — the cathedral profile holds the centre stone with quiet confidence. A statement-scale choice for engagement, a milestone anniversary, or a signature everyday piece. IGI or GIA certified, ethically sourced.
