| Term | Definition |
|---|---|
| Ancestor Diamond | Given a diamond, an ancestor of that diamond is either:
A diamond’s ancestors are all diamonds satisfying this definition. |
| API | An Application Programming Interface (API) is a set of functions and procedures that allow two software applications to communicate. |
| Application | Services which interact with the Diamond Traceability Ecosystem through defined interfaces to provide additional functionality. Applications are not part of the Diamond Traceability Ecosystem. |
| Blockchain | A public ledger which records committed transactions on a chain of blocks. The chain constantly grows, with new blocks appended to the chain to represent new transactions. Blockchain technology possesses certain integral key characteristics: decentralisation, persistence, anonymity and auditability. |

| Data Dictionary | A spreadsheet which gives a comprehensive overview of all data points required for uploading data for a diamond, at any stage of its lifecycle. The Data Dictionary is part of the Integration toolkit. |
| Data Point | The smallest unit of information about a diamond, used for traceability. It must not contain any personally identifiable information (PII). For example, 4Cs, 3D scan in STL, raw image file, etc. Data points may be classed as Traceability (level 0) data, Supplementary data (Levels 1-3) or Entity Specific data (Level Z). |

| Diamond History | A collection of data comprising:
Order firstly by diamond hierarchy, then the version’s |
| Diamond ID | A core service in the Tracr Platform Ecosystem primarily tasked with validating, verifying, and identifying diamonds. Using a combination of data, including images, videos, and reports, it is the way Tracr is able to assure that the diamond being presented to the platform is, in fact, the diamond that the holder is suggesting. |
| Diamond Integration Tool (DIT) | The system which allows participants to add and change data in their instance. By creating a simple data file and uploading it, new records are added to the instance. |
| Diamond Lookup | A tool that can be used by platform participants to view a diamond using a time-limited URL. |
| Diamond Record | A collection of data points associated with a single diamond organised in accordance with the schema. |
| Diamond Registry | A directory that identifies on which platform(s) all or some of the associated diamond record is stored. |
| Diamond UID | The globally unique ID generated by Diamond ID for a single, validated, and verified diamond at a specific time. |
| Diamond Version | A diamond and all its attributes at a given point in time (the system_timestamp). |
| Diamond Versions | All versions of a given diamond, ordered by system_timestamp. |
| Diamonds from DTC | A ‘source of origin claim’ that sightholders and accredited buyers can apply to their sight-sourced diamonds and pass it on with a diamond as it moves down the value chain. All DTC diamonds are sourced in alignment with the OECD’s Due Diligence Guidance, are fully compliant with the Kimberley Process, and originate from Botswana, Canada, Namibia, or South Africa. |
| Digital Asset | Anything that exists in a digital form that comes with a distinct usage right. Digital assets can include any form of digital information—videos, images, animations, and graphics—that is stored in computers, smartphones, digital media, or clouds. For Tracr, each diamond on the platform is represented by a digital asset. All data and accompanying metadata that Tracr possesses on each individual diamond on the platform is amalgamated to produce a digital asset that forms a holistic representation of each diamond registered on the platform. |
| Entity-Specific Data | Participant-specific data to which only that participant has access. This data cannot be shared with other Tracr participants. |
| False Match Rate (FMR) | Used in the context of the Diamond ID service, it represents the ratio of false positive matching results to accurate matches. |
| False Non-Match Rate (FNMR) | Used in the context of the Diamond ID service, it represents the ratio of false negative matching results to accurate matches. |
| Diamond Experience | A search that allows you to retrieve details of any diamond within the Trace network using its Tracr ID. The URL of the search page is https://search.tracr.com/ |
| Grading Integration Service (GIS) | A service that allows grading labs to upload a grading certificate and/or inscription number to a diamond record on Tracr. |
| Individual Tracr Instance | Each participant is given their own Tracr instance when onboarded through which they can access the Tracr platform. Each individual instance will only allow a participant access to their own diamonds and not those of other participants. |
| Integration Tool | See Diamond Integration Tool. |
| Integration Toolkit | A collection of scanner templates, CSV templates, and supporting documentation. The Data Dictionary is also part of the Integration toolkit. |
| Integration Monitoring | Part of the Tracr Management Portal that displays the verification status of diamonds uploaded to Tracr. Each integration has a status, which can be:
|

| Sight | Sights are sales that take place ten times per year. During the sales period, customers (sightholders and accredited buyers) can inspect the rough diamonds offered to them before deciding what to buy. A sight is identified by the calendar year and the number of that sight within the year. |
| Sightholder | A select group of diamantaires who have demonstrated outstanding business performance and ethical accountability. Each sightholder is selected following a rigorous procedure where the firm in question’s abilities in the core areas of business, strategic planning, manufacturing excellence, business reputation and strict adherence to a code of ethical accountability. |
| Supplementary Data | Data points relating to a diamond in addition to the traceability data. A participant can optionally share supplementary data with other participants. |

Ownership of the primary data transfers with the ownership of the associated diamond. A participant can optionally share verification data with other participants. |
| Tracr | Tracr is an advanced technology platform developed by De Beers Group to underpin trust in diamond provenance.
