Gemstone Museum Collections and Exhibitions

View exclusive highlights of museum collections for inspiration and knowledge. Their collections vary from ancient gems including the famous “Cameo de France” to the Bactrian Gold Exhibition, owned by the Afghan National Museum in Kabul. Ancient gold and jewelry often used gemstones from mining areas that no longer exist.

Many natural history museums will show both the cut version of a gemstone and the original “mineral specimen” version of it. Check e.g. the Natural History Museum in Los Angeles  for a great collection. Another one is the Carnegie’s Mineral and Gem Collection.
