How can you tell good crystal glasses?

To tell good crystal glasses, first examine them closely. High-quality crystal will give off tremendous sparkles when viewed under natural lighting and is completely free of bubbles. Gently striking the glass with the handle of a butter knife can also be helpful, as higher-quality pieces will produce a longer, clearer ringing sound. Learning about the maker by conducting online research can also help you assess the quality of your glasses. Some brands known for producing crystal wares of exceptional quality include Baccarat, Lalique and Daum. On 1stDibs, explore a large collection of crystal glasses.
