This is a fairly contemporary, 2nd half of the 20th century, decorative piece featuring a molded plaster tripartite base with stylized 'dolphins' holding a what appears in the image to be a blown glass sphere. In the Victorian era, during the 19th century, the fanciful fish forms were referred to as dolphins, even though they do not really match how dolphins look in reality. The figures were used on a wide variety of items. They are not an Asian concept, nor Asian influenced, though it is probable that this decorative piece was made in China. The estimate is based on actual recent past recorded auction sales of comparables. Retail 'asking prices' can be higher and vary.
