Paperweight was my first thought, and is what this seller thinks on a very similar item:
https://www.ebay.com/itm/Vintage-Art-Glass-Obelisk-Polygon-Pillar-Pyramid-Paperweight-/112603644548
But the seller goes on to say they don't know anything about the piece... so this may not be correct.

My first thought was a insulator of some kind........I do know it's not machine made and looks like it's from a mold

Lid to a large perfume/other bottle?

SAFTEY LIGHT TOPPER??

They put those on top of boat cabins. Its a prism, I think. Lets the light in.

Inkwell top.

 

[Duckshot]

Aw shucks, wrong again.

It does look like it could work as a deck prism also. But yep it makes a swell inkwell cover!

 

[bradyboy]

Need to know what its made of ?
Glass? Lucite ?
reason for asking is the worn edges
mold?

I got it right! Doesn't happen very often in any situation! lol

 

[bradyboy]

sorry, I don't agree
the item posted is hollow from the bottom up
Also, I don't think its glass due to the wear
it as a modern Lucite cast
IMO -

Purely by accident, today I noticed that my wife has an artsy-fartsy shaped pump-spray transparent bottle of perfume on the bathroom sink counter, whose transparent top is almost identical to the Original Poster's mystery object, except its color and "outer" shape are a bit different. The only marking on the perfume bottle is "Dali" -- as in Salvadore Dali. The larger end of the "double tapered" hole in the top's underside fits over the neck of the bottle, and the smaller hole above it fits over the push-down pump knob. There's no need for the "double tapered" hole to be in an inkwell top.
