Cut glass table lamp shade or lamp globe

This appears to be a decorative clear cut-glass lamp shade or globe with a faceted starburst and leaf-like geometric pattern. The glass is heavily patterned to refract light and create sparkle, a style commonly used in decorative table lamps and ceiling fixtures. The lower metal collar suggests it is mounted as part of a lamp assembly rather than being a standalone vase or bowl. The craftsmanship is consistent with mass-produced but attractive decorative lighting glass from the early to mid-20th century.

Cut glass lamp shades and globes were popular in the late Victorian through mid-century periods, reflecting the era's interest in decorative domestic lighting and machine-cut or pressed glass ornamentation. While not especially rare, well-preserved examples are desirable for restoration of period lamps.
