In this book, readers will gain a deep understanding of the distinct characteristics and intricate formation mechanisms behind each type of diamond.

A standout feature of this book is its in-depth exploration of nanodiamonds, shedding light on their unique formation processes. The narrative is thoughtfully organized, covering four main categories of natural diamonds and their related formation processes: 1)Interstellar nanodiamond particles; 2) Nano- and microcrustal diamonds associated with coals, sediments, and metamorphic rocks; 3) Nanodiamonds and microdiamonds associated with secondary alterations of mafic and ultramafic rocks mainly in the oceanic lithosphere; 4) Mantle-derived diamonds associated with kimberlites and their xenoliths, such as peridotites and eclogites.

With clarity and precision, this book caters to both researchers and students in the fields of mineralogy and mineral formation. This book serves as an invaluable resource, offering an all-encompassing perspective on diamond formation, appealing to those curious minds eager to delve into the captivating realm of these precious gems.

Presents an overview of the latest research on diamonds in nature Explains the formation of diamonds of different sizes in nature Provides some guidelines for diamond exploration and prospecting

Dr. Simakov Sergei Kirillovich, a geologist and diamond expert, born on 22 August 1957 in Russia. He completed his education at the Geological Faculty of St. Petersburg University in 1979. Early in his career, from 1979 to 1997, he dedicated his efforts as a Scientist at the All Russia Geological Institute. Dr Sergei Kirillovich pursued further academic excellence and earned his Ph.D. degree in 1990. Subsequently, from 1997 to 2008, he continued to contribute to the field of geology as part of the esteemed Department of Geology at St. Petersburg University, Russia. In 2013, he embarked on a new journey as the Director of LLC "Adamant," a distinguished role he has held up to the present day.
