An intriguing story about the giant phenomenal crystals, their discovery, collecting and fortune. Written by the famous collector and expert on giant crystals Ilia Deleff, Doctor Honoris Causa. Deeply convinced that every glant crystal is like a "stone book" carrying in it invaluable scientific information, Mr Deleff persistently inspired his ideas that phenomenal crystals of minerals are natural creations that must be saved and preserved for humanity. Many Western European and American museums are in possession of valuable collections or separate minerals provided by Ilia Deleff. In 1983, France acquired his remarkable collection of giant quartz crystals, exhibited in the National Museum of Natural History in Paris. In 1985, he donated to his homeland Bulgaria a similar unique collection of giant crystals. The book is richly illustrated by color photographs of crystals and contains also chapters written in cooperation with the mineralogist Dr R.I.Kostov. The chapter "Gem Treasures of Brasil" is the most complete, up-to-date, survey on the topic. The book is of use to any geological or mineralogical library, mineralogical museums, specialists in the field, collectors of crystals and all lovers of nature.

As one of the eighteen field-specific reports comprising the comprehensive scope of the strategic general report of the Chinese Academy of Sciences, this sub-report addresses long-range planning for developing science and technology in the field of oil and gas resources. They each craft a roadmap for their sphere of development to 2050. In their entirety, the general and sub-group reports analyze the evolution and laws governing the development of science and technology, describe the decisive impact of science and technology on the modernization process, predict that the world is on the eve of an impending S&T revolution, and call for China to be fully prepared for this new round of S&T advancement. Based on the detailed study of the demands on S&T innovation in Chinaâs modernization, the reports draw a framework for eight basic and strategic systems of socio-economic development with the support of science and technology, work out Chinaâs S&T roadmaps for the relevant eight basic and strategic systems in line with Chinaâs reality, further detail S&T initiatives of strategic importance to Chinaâs modernization, and provide S&T decision-makers with comprehensive consultations for the development of S&T innovation consistent with Chinaâs reality. Supported by illustrations and tables of data, the reports provide researchers, government officials and entrepreneurs with guidance concerning research directions, the planning process, and investment. Founded in 1949, the Chinese Academy of Sciences is the nationâs highest academic institution in natural sciences. Its major responsibilities are to conduct research in basic and technological sciences, to undertake nationwide integrated surveys on natural resources and ecological environment, to provide the country with scientific data and consultations for governmentâs decision-making, to undertake government-assigned projects with regard to key S&T problems in the process of socio-economic development, to initiate personnel training, and to promote Chinaâs high-tech enterprises through its active engagement in these areas.

Artificial gemstones have been well established in the trade for some time, but with further refinements in their manufacture, gemmologists worldwide are facing increasing problems with identification. In Artificial Gemstones, Michael O'Donoghue provides the definitive guide to the various manmade substitutes, thus enabling anyone handling gems to identify them accurately. Starting with the theory of synthetic gem manufacture and an explanation of the production methods used for growing and/or improving crystals, the book moves on to list and identify the materials themselves. The author lists the internal and external features and tests, and the book contains color illustrations to display the inclusions found in transparent materials. The book is completed by an extensive bibliography and a useful appendix of trade names.
