Estimated to date from the late 90s, they're beautifully frosted to soften light output, along with a pretty confetti design that spirals around the shade. 
 
Both are in excellent condition, only one flaw of note to one which is a small area at the top. At some point during it's life the internal sheen has been lost. However once hung, it's not possible to see as it's at the very top.
