The high market value, prestige, and collectibility of vintage and contemporary Lalique glass art have unfortunately attracted counterfeiters and fraudulent manufacturers attempting to replicate luxury items. Counterfeit pieces usually display inferior weight, crude mold seams, blurry signature marks, and an absence of the distinctive satin-finish frost texture found on authentic works. Prospective buyers and collectors should always exercise caution and acquire pieces through reputable auction houses, certified dealers, or official brand boutiques.
