Signed vase numbered turquoise

Nice ceramic vase with hand-painted decoration, black on a background between water green and turquoise blue (the color pulls slightly more on water green than in the photos). Its shape is reminiscent of the diabolo. Below a stamp: the letter g and a number 10.190. It has cracks on the enamelling and probably a crack on the flared part of the vase, but since it does not go down to the bottom, the vase remains usable. There are also three small chips on the upper perimeter (difficult to make them appear without having many other reflections, but they are visible in the very last photo) as well as inconspicuous spots inside. It is not in perfect condition, but its shape and especially its color being so pretty, I think it deserves its life more, and I propose it here. It measures 18 cm in height, 13 cm in diameter at the level of the upper flared part, 9 cm at the level of the base and weighs almost 500g.
