This is almost like putting an invisible lamp in your room. No matter how many times you change your rooms look this lamp will always “reflect” the new style :)
These lamps can go for $300 and up but I found a beautiful collection at nova68.com. They are not made from mercury but the effect is similar. The lamp size I like sells for $150 with free shipping and the shade has nice details. I might change it out for a white drum shade eventually.
