"It's A Gem" Ball

I found this ball in the stream.  I am assuming it is probably a duckpin bowling ball.  It has "It's A Gem"  etched into it with nothing else that I can find.

I assumed that this was the brand, but I have searched websites for the "It's A Gem" brand, and I can't seem to find it anywhere.  Any insight on this would be greatly appreciated!!
