While Tiffany reproduction lamps usually cost a great deal less than a genuine Tiffany lamp, you should be aware that some of them can be part of a signed series, and can be fairly pricey themselves. It really depends on the quality of the reproduction and its history – you might say that some of the older reproductions have become collectors’ items themselves.
A good Tiffany reproduction lamp base can become a family treasure, especially the ones signed by authentic reproduction houses. When purchasing these reproductions, keep a close eye on the quality and make sure you are getting the materials and workmanship for which you are paying.
