Sources & bibliography
This page lists every peer-reviewed article, book, standard, and vetted online reference cited across the learn section of gemmology.dev. All factual claims in those articles -- numerical data, optical constants, crystal properties, and identification criteria -- are traceable to one or more entries below. DOIs link to the authoritative record via doi.org; ISBNs link to the WorldCat catalogue. Each entry shows which learn articles cite it so you can trace a claim back to its source.
Sources will appear here as /learn/ articles are annotated with citations.
