A beautiful marble! I would tend to agree with Alley, in part because the ribbons don’t appear to dive into the base and being slightly bigger than 9/16”. I love Ravenswood and would not be upset if it was.
I feel your pain. Sellers like Sami Arim (machinemades), Bob Block and Lee (cedarman7) wrap with bubble wrap and the first two with boxes. Never had any problems with them.
