It sounds interesting! Based on your description—heavy glass, spiked or pointed bumps, and very solid—it could be a few different things, but I’d need to see a photo to identify it accurately.
Objects like that are sometimes:
- Glass paperweights
- Art glass sculptures
- Vintage glass flower frogs (used to hold flower stems in place in a vase)
- Decorative candle holders or centerpieces
- Studio glass pieces made by artists
The fact that the points are actually sharp and it’s very heavy makes me think it might be art glass or a decorative paperweight, but a picture would help confirm.
📸 Can you upload a photo of it?
If possible, show:
- The top view
- The bottom/base
- A side view to see the spikes
With that, I can probably tell you exactly what it is and whether it might be valuable.
