Abstract: Information on the International Genetic Classification of Noble Corundum is given. The scheme of location of the main deposits and occurrences of ruby-bearing complexes of the world is attached: 1 – magmatic; 2 – metamorphogenic; 3 – sedimentary (residual ancient crusts of chemical weathering, alluvial and dealluvial-alluvial placers). The location of ruby objects is shown, including the largest areas of depleted, currently operating and promising for the near future ruby deposits in 36 countries around the world. The main typological features of rubies are described. It is emphasized that all properties of rubies are determined by their primary indigenous origin. The typology of rubies is based on the principles of the relationship between magmatism and metamorphism in the formation of the groups under consideration. Hydroblasting and selective crushing methods for mining of corundum-bearing complexes are characterised. The trend towards increased research into the commercial exploitation of the primary sources of ruby-bearing complexes is highlighted. In countries with highly developed mining industries, underground mining is the main way to extract gemstones.

Keywords: ruby, ruby-bearing complex, genetic series, typology, hydraulic blasting methods, selective crushing
