Yep,, it doesn't happen often but some jewelers are putting diamonds in metals other than platinum and gold. In all probability, your stone is a Zirconian. Very nice find. Last year, with some of the clad that I cashed in, , I purchased a diamond tester. Congrats on a nice find.
Congrats on the nice pendant!
Jewelers are not only putting diamonds in silver but are putting them into titanium and tungsten carbide. I just found this out talking to the folks at Ben Bridge. Not just lab created.....

The funny thing is that all the gold rings, bracelets or other valuable objects, I have found not more than two meters from where I begin and after that nothing. It looks like something is guiding me!! [emoji1]
