From what I can tell, all Shift Stones are crooked on the left All-Round Gauntlet

Edit (1/18/2025):

This appears to be the case as well on the recently fixed left Martialist Wristband. The stubborn stone in particular may appear to ever so slightly float above the right Martialist Wristband, but it does not appear shift stones have the same tilt as when equipped to the left
