Returns kill jewelry margins, and most are fit-related. A clear sizing chart on every listing prevents the mistake before purchase.
Rings. Show US/EU/Asia equivalents (our ring size conversion guide) and a printable ring-sizer. Push adjustable styles to avoid the problem entirely.
Bracelets. Measure wrist circumference; state both inner length and extension range. Cuban and bangle buyers especially need scale context.
Necklaces. A length diagram (16/18/20/24″) on a torso solves the most common necklace doubt. Pair with layering guidance.
Delivery. Provide charts as PNG for web and PDF for packaging. a wider returns-reduction strategy covers the wider strategy; sizing is the single biggest lever.
