A number tying a stone to a report.
Also known as: Diamond report number, Laboratory inscription gemstone
The identifier linking a graded gemstone to its laboratory report, sometimes inscribed on the stone.
Links a graded stone to the laboratory report describing it.
Contexts: Public information
Inscribed on the stone rather than only on the paper, because a certificate and a stone can be separated and recombined — the inscription binds the two so the document cannot be transferred to a different stone.
Contexts: Public information
Identifies the stone and says nothing about its value; grading and pricing are separate matters and no record here addresses either.
A report number identifies a stone; it is not a statement of quality or value.
Contexts: Public information
A report number printed on a certificate and, for many stones, laser-inscribed in microscopic letters and digits around the girdle of the stone itself.
