Iron meteorites rust in a damp cellar. You fingerprint a polished cut face in one evening. In the overview Security for collectors this is a small piece with a certificate that holds the price.

Storage

Dry, cut face covered, not on an open shelf above the heater, and not in the wet. You do not touch the polish with bare fingers. The certificate sits in the document cabinet, the stone in the cabinet if the sum calls for it.

When someone comes

Small, and without a certificate often just a stone to the offender. For you the certificate is the proof. Losing both in one place is unnecessary. The list states type, weight, whether a cut face is there, proof.

The folder

Weight, classification as far as documented, certificate, photo of the cut face.
