Yes, I think this is too small to be a deck prism…….now I think it’s a crystal paperweight for a desk.

There was a sale of this prisms several years ago by the Public Broadcast network. The original ones were for light in the lower decks of sailing ships, really a unique way to get light below the deck.

A deck light or deck prism. It’s a prismatic glass set into a ship’s deck, to let natural light below. … The earliest deck prisms with provenance are from the 1840s. … the HMS Terror did not have portholes, but used Preston’s illuminators instead.

Those are my best guesses!

It is a copy of a “deck prism” from an old sailing ship. The clear prism was fitted in the ceiling to provide light to the room without it leaking.

It was used on the deck of old whaling ships so the light from above would defract into the below deck of the ship. They obviously could not have windows near the water line. The flat part would be flush with the deck. and provide light to under

This is a ship’s deck prism. It would be inverted and installed flush with the deck to allow sunlight to filter into the hold below.
This looks a a re-pro that was sold by Restoration Hardware in the 1990’s.
