And by brand, I mean a cattle brand (branding iron, that is!). In GAC: Origins, Jewel was showing off the house that is now her studio and the kitchen has a really cool table with some chairs. On the chairs she pointed out that they were branded with her brand, the rocking Jewel. I didn't realize she was serious, I thought it was something that was just on the chairs and was a little joke she had. But then later in the show, she's on a horse and on the front left leg of the horse is her brand "the Rocking Jewel" again! And when they played a clip of Stronger Woman at the end of the show, I noticed it's on her guitar strap, too.
It's the jewel-shape with an arc beneath it (like a rocking chair's base)...get it, the rocking Jewel?
