A radiant at three carats
At this weight a radiant faces up at roughly 9 by 7 mm in its longer form, slightly less in a squarer one. Its crowded facet pattern scatters light across the entire table, so candlelight or office fluorescents both wake it up. Beveled corners spare it the chipping that pointed shapes risk.
Choosing the setting style
- Clean solitaire: the octagonal outline on a rounded, unadorned band.
- Pavé shoulders: small stones carry the sparkle a short way down each side.
- Hidden halo with pavé band: brilliance under the center and around the finger.
Gold and platinum compared
Platinum grips a heavy center reliably and stays naturally white. White gold mimics it at a lower outlay, though its rhodium coat wants renewing every few years. Yellow and rose gold create contrast against the bright stone. Band widths range from about 1.8 to 2.5 mm.
Looking after a large radiant
Hand cream films the pavilion and flattens the fire; a sudsy rinse with a soft bristle brush fixes that fast. Leave it on the nightstand during workouts, and give it its own pouch so the band stays unmarked.
