Provenance
How RubyCloud represents origin, documentation and chain of custody — and what it means when information is not recorded.
Provenance is the documented origin and chain of custody of a stone — where it came from and how it moved from extraction to the faceted gem. RubyCloud presents provenance as recorded documentation, not as a qualitative ranking of origins.
Rubies hosted on RubyCloud are of documented Greenland origin. Each dossier records the mine and region where available.
Each ruby dossier may record origin, a provenance narrative, traceability information and responsible-sourcing information. Where any of these are not recorded, that is shown clearly rather than implied.
Treatment is recorded as one of four states — Untreated, Heated, Other, or Treatment information not recorded. Missing treatment data is never treated as untreated.
Where available, laboratory reports are listed on the dossier. A ruby may have zero, one or several reports on file. A report documents identity and, where determined, attributes such as origin or treatment.
Where traceability information is recorded, it is presented on the dossier. Traceability describes the documented chain of custody; its absence is shown as not recorded rather than implied.
RubyCloud distinguishes four states: recorded (the information is on file), not recorded (no information is on file), not applicable (the attribute does not apply), and document unavailable (a document exists but is not currently available). Missing information is never used to infer a positive or negative claim.
Provenance and responsible sourcing are connected. See the responsible sourcing page for how this information appears on RubyCloud.
The Origin & Provenance section of each dossier presents the recorded narrative, mine and region, and traceability information where available. It links here for the full approach.
Recorded
The information is on file.
Not recorded
No information is currently on file.
Not applicable
The attribute does not apply to this stone.
Document unavailable
A document exists but is not currently available.
