CU Crystal Glass

CU refers to the culet on crystal glass, the small face on the pointed tip. Culet size impacts durability and optics. Large historical culets have given way to minimized modern culets. An ideal culet balances light performance and protection. Cutters carefully shape and align the culet for symmetry. On rounds, tiny culets minimize leakage and maximize sparkle. For crystal points, a small culet prevents cleavage. Precision cutting tailors the culet to each shape for ideal brilliance.
