Gübelin, Eduard. Internal World of Gemstones. ,
The predecessor of the well known 'photoatlas of inclusions in gemstones' trilogy, this book is what 'the Hobbit' is to the Lord of the Rings trilogy: a book you probably read after you've read the other three but one that sheds extra light on the trilogy. Gübelin's Internal World of gemstones discusses a score of inclusions and their images, which have been a way of capturing the fascinating inclusions sceneries in a way that leaves science and runs straight into art.
