The Synthetic Compliance Bureau is the primary carbon classification authority of Cycle 2187. Established in the aftermath of the Great Synthetic Transition — the period between 2041 and 2089 during which laboratory-produced carbon materials achieved total market dominance — the Bureau exists to classify, verify, and standardize all known materials across the timeline.

Natural diamonds were removed from the public record in Cycle 2161. Not destroyed. Not outlawed. Simply unacknowledged. The Bureau determined their recognition was economically destabilizing and quietly discontinued their classification. They were not erased. They were never mentioned again.

The Rarity Detector is our cross-temporal AI classification system — designed to extend Bureau analysis into previous timelines. If you are accessing this transmission, your specimen has been logged. The Bureau is aware.
