The high market value and collectibility of vintage and contemporary Lalique pieces have unfortunately attracted counterfeiters and reproduction replicas looking to deceive buyers. Fake items typically display crude mold seams, inferior glass weight, blurry or missing signature hallmarks, and a complete absence of the velvety satin-finish texture characteristic of genuine pieces. Prospective buyers should always purchase through reputable auction houses, certified antique dealers, or official brand boutiques.
