Gem-quality ammonites of Canada: Features of mining and processing
Bibliographic record
Abstract
The current world market widely presents ammonites for the collecting and interior decoration purposes. In the last decades, jewellery and souvenir style ammonites enjoy growing demand. This article considers the methods of mining and processing of Canadian gem-quality ammonites, as well as the detailed study results on their gemological characteristics. Canadian ammonites are popular on the market owing to their fossil nacre and colored iridescence. Fragments of mother-of-pearl layer are used for making cabochons known under the commercial name of ammolite. Iridescence of ammolite is associated with the remaining lamellar aragonite layers of ammonite walls. The color of iridescence is connected with the structure and size of aragonite microcrystals. The experience of mining and processing of ammonites in Canada can be useful for Russia holding considerable reserves of the mineral.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
