The authors, Sotheby's jewellery experts, evaluate many millions of pounds worth annually and thus handle a complete crosssection of what is available on the market. They have specially selected the 833 colour illustrations to show what to look for and, equally important, what to avoid.This essentially practical book is unique in explaining why values vary and the individual points important for each category. A major section is devoted to the identification of the major gemstones and the testing methods to assess quality and detect fakes.
⚠️ WARNING (California Proposition 65):
This product may contain chemicals known to the State of California to cause cancer,
birth defects, or other reproductive harm.
