Vintage vase in enamelled sandstone

The vase is in perfect condition, no cracks, no gaps, no splinters. It is made of enamelled sandstone, beautifully crafted. The grain of the earth is very fine, and the enamel refined. The vase is straight, with at the bottom the element "flower picnic" added, which allows to block each stem in its small location. The vase may be suitable for the practice of ikebana. The piece is not marked, but it is probably a french work of the 50s.
