Abstract
Chinese freshwater cultured pearls are playing an increasingly important role in the industry. In the 1960s, the cultivation was done primarily by individual families or indigenous farmers. In recent years, however, pearl culturing has shifted to large, modernized farms and the use of different mollusks, resulting in large quantities of a highly desirable product. In 1999, global production of cultured pearls was estimated at 1,262 tons, with Chinese freshwater cultured pearls making up 1,000-1,200 tons of that amount. Most of the farms are located along the banks of the Chang Jiang (Yangtze) River, where more than 400,000 people are engaged in the pearling industry. After 2-5 years of propagation and 1-3 years of cultivation, the implanted mussels produce jewelry-grade cultured pearls in a range of shapes (mostly off-round and baroque) and colors; most undergo color treatment before being sold. Luster ranges from poor to excellent, with larger cultured pearls (over 10 mm in diameter) typically showing low luster.

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; both teacher heads agree on what is shown here.
