Gemmology 315 Class Notes by Charles Lewton-Brain (ACAD) Last updated Dec 4, 2016
(Myarticles are at the Ganoksin Project.)

The following links are only starting points. For in depth research go digging further at gemmology world, pala gems and other sites listed here. The key books (in the latest edition possible) are Gem Testing by Anderson, Handbook of Gem Identification by Liddicoat and Gemstones of the World by Schumann. Matlin and others are also good. The ultimate reference is Gems by Webster. Please let me know of dead links, and links that should be added to this page. Thankyou.
