These were made by Graffix. Graffix used to make ceramic hookas/bongs and were selected by Lava Lite back in the day to make the Icon series. The one pictured looks like one of the early prototypes used as a proof of concept. They probably made these ones without the ring that holds the globes because those would require special tooling to get the right dimensions. I have a similar one without the top ring that looks like Kenny from Southpark.
Yes, probably a Graffix prototype. Quite cool.
