Book excerpt: Viewed through a microscope, some gemstones and crystal specimens reveal amazing photogenic inclusions and surface features that could well be mistaken for abstract art. With the use of various lighting techniques and careful composition, gemmologist and photographer Anthony de Goutière has photomicrographed many of these unusual and artistic scenes. The author hopes to inspire other gemmologists to search for and photograph the elusive beauty of gemstone inclusions. *It is necessary to have an account when ordering the GooglePlay eBook, and an Android device with the GooglePlay app - or the app on your computer.
