Share the full calculator
Give customers a direct way to check an estimate on their own phone. Add an optional campaign label to the QR link for analytics systems that record UTM parameters.

UTM tags only help measure referrals if an analytics tool on the destination records them. KaratWorth does not identify people from this link.
Paste once

Offer a useful check
Visitors can estimate metal value by weight and purity without leaving your page.
Keep the quote clear
Explain that local taxes, making charges, assay, and buyer terms can change the final offer.
A note for responsible publishing
The widget is designed to clarify a calculation, not to make a quote on behalf of a buyer. Add your own local information about taxes, making charges, assay, and payout terms. See the methodology before publishing.
