Here's a really fancy chicago mosaic lamp base. It is probably the most ornate chicago mosaic lamp base i have owned, with a lot of detail in both the bottom and even on the stem! The base stands 22 1/4 tall and the bottom is just ovre 8 1/2 in diameter.

You ask how i know this is a chicago lamp base? The biggest telling tale of this (besides the design which is clearly chicago mosaic) is the shade rest, which has na opening of exactly 2 1/2. This would fit into a chicago mosaic shade which would have its cap directly attached. If you want to see examplse of this, please check out and look under the chicago mosaic tab, where you will see many designs from this company.
