It's an impact-glass spherule. There's another one to the right,
just right of center. It's got a soil coating. Any handful of lunar
soil is loaded with these things. Most are in the 0.1-mm range. The
biggest I've seen is 2 mm, but I think there's one of ~2 centimeters
in the Apollo collection.

I suppose they're the lunar equivalent of tektites.

What's the little round black sphere in the upper left of the photo?
Is that some sort of meteoritic spheroid?
