Remember: Earring Carat Weight Is Measured as "Total Carat Weight" (ctw)
When a pair of diamond studs is listed as 1.00 ctw, each ear wears a 0.50-carat (~5.1mm) diamond. For a main first-lobe piercing that pops in photos and across a room, 1.00 ctw to 2.00 ctw (0.50ct to 1.00ct per ear) is the modern luxury standard, while 0.25 ctw to 0.50 ctw is ideal for second and third lobe piercings.
