High-temperature and high-pressure treatment of diamond is becoming an important technology to elaborate diamonds. This is the first book providing a comprehensive review of the properties of HPHT-treated diamonds, based on the analysis of published data and the work of the authors. The book gives a detailed analysis of the physics of transformation of internal structures of diamonds subjected to HPHT treatment and discusses how these transformations can be detected using methods of optical microscopy and spectroscopy. It also gives practical recommendations for the recognition of HPHT-treated diamonds. The book is written in a language and terms which can be understood by a broad audience of physicists, mineralogists and gemologists.

Raman Spectroscopy in Archaeology and Art History highlights the important contributions Raman spectroscopy makes as a non-destructive method for characterising the chemical composition and structure and in determining the provenance and authenticity of objects of archaeological and historical importance. It brings together studies from diverse areas and represents the first dedicated work on the use of this technique in this increasingly important field. Coverage includes: An Introduction to Raman Spectroscopy, including practical aspects of Raman spectroscopy and complementary techniques; Dyes and Pigments; Artefacts; Biological Materials and Degradation; Jewellery and Precious Stones. The book contains a broad selection of real-world examples in the form of case studies to provide the reader with a true appreciation of the procedures that need to be invoked to derive spectroscopic information from some of the most challenging specimens and systems. Colour illustrations of objects of investigation and a database of 72 Raman spectra of relevant minerals are included. With its extensive examples, Raman Spectroscopy in Archaeology and Art History will be of particular interest to specialists in the field, including researchers and scientific/conservation staff in museums. Academics will find it an invaluable reference to the use of Raman spectroscopy.

Diamond is the record-setter in many mineralogical properties such as hardness, diffusivity, thermal conductivity, purity, and covalency of bonding. Similarly, diamond, as the premier gemstone of the mantle holds primacy for geological features such as age and depth of origin. Diamond was among the first crystalline structures to be solved by X-ray diffraction and the first materials measured for their Raman spectrum. At more than 80 billion USD in yearly commercial value, diamond sets the record for the most traded, valuable mineral on the planet. Despite its chemical simplicity, diamond has been the object of more research effort, and had more scientific and popular press pages written about it, than any other mineral.
