The rapid growth of gemological sciences and mineralogy demands a dictionary such as this for gemologists, mineralogists, geologists, jewel dealers, industry and hobbyists. With some 16,000 comprehensive definitions, supplemented by more than 250 diagrams and figures, this is a one-stop reference to any matter dealing with gems and gemology.

The perfect reference book for everyday use, it provides definitions written in clear, jargon-free language readily accessible to every level of reader.

Following debates surrounding the anti-social turn in queer theory in recent years, there has been a renewed interest in the role of activism, the limits of the political, and the question of normativity and ethics. Queer Futures engages with these concerns, exploring issues of complicity and agency with a central focus on the material and economic as well as philosophical dimensions of sexual politics. Presenting some of the latest research in queer theory, this book draws together diverse perspectives to shed light on possible ’queer futures’ when different affective, temporal, and local contexts are brought into play. As such, it will appeal to scholars of cultural, political, literary, and social theory, as well as those with interests in gender and sexuality, activism, and queer theory.
