Abstract

Rubies from the Prilep dolomitic marble contain numerous diaspore inclusions, resulting from oriented intergrowth with corundum. In the world of gemstones, this phenomenon has been recognized as diasporescence, which has to date been researched only in the cases of corundum crystals from Macedonia. The paper describes the importance of diasporescence for the appearance and thus the quality of rubies, in which the inclusions of diaspore are also a distinctive character for the determination of the origin of this renowned gemstone. Diaspore is colourless to white and affect on intensity of red to pink colour of ruby as a gem.  Macedonian rubies are the only rubies from around the world with inclusions of diaspore and that´s why also the only rubies with optical phenomena diasporescence.
