18K Gold Diamond Sapphire Stud Earrings

The piece

A blue sapphire center with natural diamond around it, 7mm across, prong-set in 18K gold. 1.34 carats of sapphire against 0.40 carats of diamond — a ratio that keeps the color dominant instead of letting the white stones take over, which is the usual failure on halo studs this size. 2.50 grams for the pair. Studs live close to the face and get looked at directly, so the setting has to be clean from the front rather than just from a distance. More across our women's collection .
