Ginkgo brooch Copper

Natural leaf of ginkgo biloba dehydrated and covered with a resin film. The ichō (Ginkgo biloba) is one of the tree species most familiar to the Japanese. Favorite when it comes to treeing parks and boulevards, it also has a great presence among the giants with treatment of sacred trees in Shinto shrines. The ichō is thus perfectly integrated into the landscape in which the daily life of the Japanese takes place. It is believed that the ichō reached a respectable geographical extension throughout the world between the Mesozoic era and the Neogene period of the Cenozoic era , but which about a million years ago entered a slow decline, until dangerously close to its extinction. Its original area is located in China and although there is no unanimity on when it was introduced in Japan, its arrival must have occurred sometime between the beginning of the Heian period (794-1185) and the end of the Muromachi period (1336-1573). The species has most likely been in Japan between 600 and 700 years. The ichō, perhaps a survivor of the ice ages, is a solitary tree, as there are no other species of the same genus or other genera of the same family. It is spoken of as a living fossil. The Ginkgo Biloba is a very strong tree (For a reason it has survived so many millennia with little change). When the atomic bomb fell on Hiroshima, one of the few living things that survived being less than two kilometers from the hypocenter of the explosion were four Ginkgos.
