Entered purity is an assumption, not an assay. Estimates exclude refining losses and other costs.

01 / THE LOT

Every item.
Its own assumptions.

Enter grams, troy ounces or pennyweights. Keep karats and fineness distinct, and subtract non-metal weight before valuing the lot.

02 / THE OFFER

One reference.
A clear calculation.

Set your own price and source. Compare an offer with the calculated melt estimate. The difference is a spread — not a profit forecast.

03 / THE RECORD

A quote you can
come back to.

Save an immutable snapshot, fork a revision, and share a customer-facing PDF without internal spread notes. Keep internal details in CSV or a local backup.
