There seems to be a lot of fake Lalique out there on Ebay. None of the items pictured here are genuine Lalique. Most of it is Czech Glass which has had a stencil mark added. These are acid-etched with a stencil, although I have seen rather poor attempts at pen-etching the Lalique signature. You can tell from the shaky cursive script. The most common is the small vase with nudes/grapes. This is a Czech creation.  You can go to several different websites and check this for yourself. Desna-glass.cz, ciocollection.com, and glass-originals.cz are just a few. From the Desna Glass website, "Small Grape Harvest", designed by Frantesek Pazoruek. Frantisek Pazourek was the head designer for the Heinrich Hoffman Glassworks in Bohemia during the 1920's. Most sellers call this "Baccantes" or something similar.  The latest fake Rene' Lalique to hit eBay is the "Forrest" vase, which is picture number 1. This is actually by Josef Inwald, from his "Barolac" line. If you google Inwald Forrest vase, you will find a wealth of information on that vase.  Also, the "Desire" vase, # 25623 01 230 designed by Curt Schlevogt and the "Dance" vase designed by Artur Pleva #25531 00 240, are showing up frequently fraudulently stenciled "R Lalique France" You will also see the "Torso" sculpture, designed by Eleon Von Rommel. #27226 00 280, and "Susanne at her bath" designed by Curt Schlevogt # 80045 00 135 all listed as Rene' Lalique.  The Weil "Pansey vase and "Cherries" vase are also frequently listed on eBay with fake Lalique signatures. There is an excellent website, rlalique.com, which has a section called "R Lalique Police" which has current suspicious online auctions listed, as well as a free authentication service. They also have a section on common fakes, copies and forgeries, and modern Lalique Crystal being sold as Rene' Lalique.  There also is a lot of information about genuine Rene' Lalique at auction around the world. Check it out. You won't be disappointed. Another great resource is the Glass Message Board, glassmessages.com, which allows people to post photos of items and will give the name of a piece, maker, designer, era produced, etc. This is an invaluable resource for the glass collector, and I have found them to be extremely helpful. The phrase "Let the buyer beware" holds very, very true when it comes to buying Lalique on eBay!
