Featured Mark on Space Age Cuff Links

From the "I wonder what that mark is" pile. Tests sterling, appear to be lapis, have a space age / planet / orbit / galaxy look to me. The only mark is the squiggle I've shown. It's a little different on each cuff link, and oriented differently, so I've shown both. Kind of looks like a script capital letter B. Any ideas as to maker?
I have searched a bit on sterling cuff link with space, lapis, planet, and did a Google image search for the links as well as the mark. Nothing.
Thanks for any help!

 

Sloppy excess solder,"B" is a piece of wire soldered to the base.Could be hobbyist/student work.

 

These do not look like a student's project. Don't forget we are viewing something with roughly 8x magnification in the last two photos.

I think that B shape is a maker's mark, but don't recognize it off hand.

They are very cool. Would think they would easily find a buyer!

 

No clue but very cool!

 

Love those, says the space flight and astronomy geek.

 

Ditto what OBB said.

 

looks like that Russian ' B ' , again....
& that star....kinda fits that !

 

Thanks everyone. I think they are very cool, just wondered if that mark might be recognizable to anyone.

 

Not to me, but I'd wear those. As a woman who takes a 34 sleeve, I end up with men's shirts.
