Japanese artist Mitsuru Koga carves these tiny vases from beach stones he finds himself, which are large enough only for a single leaf or small flower. The vase in the first picture measures a minuscule 12 x 37 x 31 mm. The ordinary common beach stones are transformed into little gems of one of a kind design.
Koga says, â€œIt is always continuous discovery and surprise. I wish to create an intermediate bridge between nature and human beings.â€
