Have seen this style of opalino color glass attributed to Archimede Seguso with a label. It could possibly have been assembled by the Marbro Co. It is a monumentally beautiful lamp. Has a chip on the middle glass ring under the chrome dividing ring and is VERY difficult to see unless you are specifically looking for it. I didn't even notice it until I had owned it for a couple of years.
See the two photos which are different views of the same chip. The lamp is mounted on a Lucite base which could have been a later addition. Finial not original but is an alabaster with brass fitting that says "Made in China". Have included a photo which shows a Murano bowl that matches the lamp. 36 inches tall to top of finial x 6 wide diameter base.We are not experts, but do our best to research and date and identify all items.
