Gulliver devotes a number of pages to similar small posy type vases with many, like yours, showing a four way crimp in varying degrees of size. Most examples show applied decoration - showing stylized Acanthus leaves, nuts, fruits etc., so your is a more simple version. Gulliver seems to have block described these as being dated to c.1885, and "formed in creamy white/opal white glass over pale ruby". Height is usually somewhere between 4 and 6 inches, and like yours they usually had a polished concave pontil mark. Probably for obvious reasons, Gulliver omitted any formal attribution on any of his examples, so we will go with Lustrousstone's experienced thoughts.
