How do I date these pieces?

Dating relies on stylistic markers associated with periods spanning from the 1910s through the 1940s. Art Deco geometric forms and specific material combinations indicate the era of manufacture. Evidence in the titles points toward the 1930s as the most common decade for these lighting fixtures and associated decorative objects.

Where were these lights used?

These fixtures served utilitarian and decorative roles in domestic interiors, offices, and public spaces. Standard lamps and table lamps provided task or ambient illumination in sitting rooms and studies. Wall sconces and ceiling globes mounted directly onto architectural surfaces to distribute light evenly across a room.

How do I care for marble and onyx?

Stone bases require gentle dusting with a dry cloth to prevent surface scratching. Avoid abrasive cleaners and acidic liquids that can etch polished stone. Protecting the natural mineral surface preserves the finish of table lamps and decorative mounts over decades of use.
