Each entry was accompanied not just by a gemstone type, but by a coordinate—a specific mine, a precise depth, and a date of extraction. Most atlases of inclusions are clinical: a photomicrograph

Anya leaned closer. “Finkelstein had a theory. He believed that inclusions were not accidents of crystallization. He believed that the Earth’s crust was a kind of slow, deep-time recording medium—like magnetic tape. When certain extreme pressures or temperatures occurred, or when something from outside interacted with the planet’s mantle, the minerals crystallized around the evidence. A tooth from a future species. A gear from a machine that hadn’t been invented yet. A star chart from a sky that doesn’t exist yet.”
