I recently bought this very nice neodymium vase - pale amethyst in sunlight, pale blue under fluorescent light.
It has 4 rows of 5 'scallops' that are created with two flat surfaces in each case. The base is faintly hollowed out so the vase rests on a thin rim rather than flat.
I suspect it is Czech but have no idea as to maker or when it may have been made.
