This is a replica of a clever little invention called a deck prism.
Before electric lighting when the risk of a flame below deck on a wooden boat was too great, deck prisms were fitted to bring natural light into the cabins below.
The flat side was fitted flush with the deck up top, with the pointed end refracting light through the prism and illuminating down below!
Not only is it a wonderfully ingenious solution, they are also beautiful in their own right.
Use as a paper weight or styling piece.
