Want to learn more about the Czech national gem? Accept our invitation to an engaging lecture by Mgr. Jan Bubal, curator of the mineralogical collections of the Museum of Bohemian Paradise in Turnov.

Garnet is not just a name for one mineral, the Czech garnet, but for the whole supergroup of minerals, which includes over thirty different mineral species with similar properties, which is conditioned by their similar chemical composition and the same structure. Garnets as a group are among the most colourful minerals ever; with the exception of the deep blue, they cover the entire colour palette: they include various shades of red, purple, brown, yellow, green; garnets are also black, but also clear. Bohemian garnet can be defined as a chromium-rich pyrope. Although it certainly does not stand out for its size, cut stones over 5 mm are rare and cuts over 6 mm are rare and very expensive, it impresses with its blood red colour. Pyropes are found all over the world, but Czech deposits surpass the world's occurrences in the uniform quality and colour of pyropes, which allows the use of an economically viable method of their extraction and processing.
