I have to give credit where credit is due. David (Langhaugh) directed me towards Galliano Ferro on another posting. I found a similar piece on ebay offered by 20th Century Glass and it was described as being produced by Jaffe Rose. I contacted Wayne and told him I believed that Jaffe Rose was actually an English Importer and not a manufacturer and that you could also find Jaffe Rose stickers on porcelain and such. He asked if I knew who it was by and I told him that Galliano Ferro was a possibility that had been suggested to me. He found the auction by Svazzo and sent me the auction number, as he agreed that his piece was also by GF. In all fairness, Wayne found the piece and I simply passed on the info after he sent me the item number. The piece Wayne has for sale is the same shape as mine with an amber insert instead of cobalt.
By the way, it is a bowl and is approx 6.25 inches in diameter.....
