Gold cicada on a jade leaf, Ming-dynasty China, 15th century AD

No banana for comparison, so quoting frim the article ^^ "The wings of this cicada are 1.7cm long, about 0.8cm wide, and only 0.2mm thick – like two little pieces of gold organdie. The leaf is 5.2cm long, 3.2cm wide, and 0.2cm thick, and is made from a piece of first-class Hotan jade from Xinjiang."
