Provenance

A diamond's provenance object details where it originated from.

Unlocking provenance

Please note

After the 21st of May 2025 the provenance for all locked diamond's on Tracr will be hidden. To unlock the diamond's provenance the diamond must be unlocked. See the unlock documentation for details on how to unlock a diamond.

Producers can always see the provenance for diamonds they have uploaded. Once a rough diamond is transferred to another Tracr participant its provenance becomes locked. Unlocking a diamond will permanently unlock its provenance information. Once a diamond's provenance is unlocked it will be shown in all interfaces and APIs.

Locked diamonds always have an empty provenance_name, but the values of the other fields will change depending on whether the diamond has single origin:

• provenance_type will display as Country if the diamond has a single origin or Entity if it has multi origin available.
• country_code will never be returned if the provenance is locked.
• is_country_code_available when true indicates that the locked diamond has single origin available after unlock. When false it indicates that the diamond has multi origin available after unlock.

Note: in future revisions of the API provenance_type and provenance_name will not be returned if the diamond is locked.

There are some examples of provenance values below.
