Entitled ‘Stone pattern’, an interesting exhibition of precious and semi-precious stones opened today (8th November) at the National Museum of Mongolia in Ulaanbaatar. The  mineral exhibition was collected by the famous Mongolian chemist and geologist G.Gongorjav, who over the course of 50 years travelled to every corner of the country in search of precious gems.

Many of the rocks have been transformed into unique objects; everything from the Cyrillic alphabet and Roman numerals to figures of Arabian sheikhs. On show are such gems and minerals as ruby, chalcedony, sardonyx, malachite, granite and egg stone. More than 400 minerals are exhibited in the form of modern art. The most expensive item is a 1mm Mongolian diamond. G.Gongorjav's collection has previously been on public display in 1994-1996 and 2000. The exhibition lasts until 13^th of October.
