I have a vintage Alhambra MOP 5 motif bracelet, and am thinking of getting a diamond tennis bracelet or bangle to stack with it. Is that a bad idea in terms of wear to the VCA MOP? I'm a bit concerned that the diamonds will scratch up the MOP. Is there a particular diamond bracelet/bangle style that won't have as much impact on the MOP? Or is there a length that would be ideal to stack? Thanks in advance!
