The present invention relates to a decorative lamp comprising a source of light and a shade of a translucent or semi-opaque porcelain material and its manufacturing method. The lamp further includes at least one decorative element of a material of greater opaqueness than that of the porcelain shade located on an inside interior surface of the shade to block the passage of light to reveal its form when the source of light is turned-on and not being visible to the naked eye.
