- Additional Information: Without a doubt, gogottes are among the most extraordinary objects created by nature: sources of inspiration for artists, they figure prominently in the greatest private collections and museums. From a geological point of view, a gogotte is a sandstone concretion with siliceous cement. It consists of grains of sand cemented in place by silica deposited by water circulating within the sand layer. Chemically speaking, a gogotte consists almost entirely of silica and therefore has more or less the same composition as a quartz crystal.
