Whoa! Frozen jellyfish lamps?

Well here's a turn-up for a business idea...

Take a jellyfish. A real jellyfish, which has 'died of natural causes' and been harvested by these lamp makers.

Freeze it in liquid nitrogen and encase it in crystalline epoxy.

They glow in the dark, due to the jellyfishes’ natural bioluminescence.

They aren't ridiculously expensive, and there are paperweight and even small pendant versions...

It's a hopeless old-world website, and there is really no information about the claims about the harvesting, so approach with some environmental diligence.
