Hello � � Crystal glass and geometric glass refer to different characteristics. � � Crystal glass is the material of the glass. Offers higher image clarity and is highly scratch resistant. � � Geometric glass refers to the shape of the glass or frame. It covers more modern and angular designs, such as hexagonal or square, rather than classic round or oval forms. In short, crystal glass indicates the material type, while geometric glass refers to the design shape. The geometric expression in our products describes the model and design form of the glasses. Thank you for your interest. � � � �️ by Harmony � �
