I was about to say that if you had a gold wedding band, it probably wasn’t the quality of gold you thought it was. Also, it’s probably why the techs might have missed it at first as bands are typically gold.
Or, just use a really powerful electromagnet to get a response from something that is paramagnetic, like an MRI.
To your point and to clarify what you mean for anyone else, pure tungsten is paramagnetic, but its the iron (or other) binders that are used in tungsten carbide that are more responsive.
Ah. That’ll do it.

Tungsten carbide is only very weakly paramagnetic… you need to mix in other metals to get a strong response…
