A Town of Passionarians

... Yakutia in the middle of the twentieth century, only 4 percent were found suitable for industry-scale mining. In the late 1960s, the future Academician N. V. Sobolev proposed a method of using minor mineral inclusions as markers of the presence of diamonds: specific types of pyropes and chromites.

Diamond Today and Tomorrow

... Comprehensive investigations of diamond growth, as well as the study of its real structure and properties made it possible to grow single crystals of diamond with a mass up to 6.0 carats, which is important for practical applications. Certainly, natural diamonds are extremely beautiful. Yet, there are no twins among these crystals, while today’s science and engineering need high-quality diamonds with certain prescribed properties which have to be the same in all crystals. Such diamonds can be grown ...
