I was too embarrassed to ask my mom, so I’m asking here — does anyone know what this crystal object is?

Instead, tucked inside a velvet-lined box, I found a set of small, peculiar glass objects.

When I first looked at one, I was completely confused. It was a clear, faceted crystal object that looked exactly like a miniature piece of gym equipment. I picked it up and rolled it around in my hand. It was too small to be a paperweight and too heavy to be a toy.

I jokingly told my mom that it looked like a “baby dumbbell” for an infant who really wanted to get in shape, or perhaps a fancy “bone for a glass dog.” She laughed and suggested it might be a weird vintage salt roller, but neither of us actually had a clue.
