I just purchased a Lalique Saint Hubert glass on eBay but am not sure if it is authentic. I already own one of these glasses which has a different mark. Am also concerned because the seam on the stem is more pronounced than the one I own already. Image 1 is of the seam, image 2 is the mark which is suspect to me and image 3 is the mark on the same model glass that I previously owned. Does anyone know if my purchase is authentic Lalique Saint Hubert??
