Reminds me of a ranch brand for livestock.....
the Bar 8 something?? Don't know what that forked half circle symbol could be though?? Teepee? Rising sun? a drop?
I almost want to say it's an "Atheism" symbol. Yes, I realize the oxymoron there. It looks to be a variation on the "Eternal Atheist" design shown here.
Just spitballing of course, but I can see the Alpha & Omega (which is a popular mocking point), and the symbol for Infinity.
its alexander ovechkin's necklace pendant. he's a superfamous washington capitols hockey player. his player number is 8, and he's russian, so thats what the shape of the top thing is... one of those steeples.
