I've tried everywhere I can think of to identify this, all to no avail. From my research, it appears to me that it may be a form of crystalline glaze finish, but I can find no Royal Doulton crystalline glaze pieces to compare it to!It's hexagonally shaped with ever-so-slightly concave walls, and is 10 1/2" (26.7 centimeters) tall. The glaze is very thick and rich, as is the blue/green coloration, both of which are on the interior of the vase as well as the exterior. It's trimmed in matte gold; the opening in a very finely articulated pattern with raised beading. The same 'checkerboard' pattern that extends around the exterior at the opening is also around the interior opening.The bottom has a Royal Doulton stamp (c.1902-1922) and 2 sets of incised numbers: "1359" and "418". Both are under the glaze.I'd like to know what this type vase is actually called, who the designer might have been, and an approximate value, as I'd eventually like to sell it. If anyone can help me with any of these, or let me know of someplace I might find the answers, I'd be REALLY grateful...
Thanks!
