Costum problems with VCA Alhambra Mother of Pearl ( Shell ) necklace?!

are you wondering if it's not durable because of the mother of pearl? it is more delicate then other materials used in the alhambra collection but if you treat it like a pearl it'll be fine!
 
My friend shipped a MOP VCA necklace via fedex from Canada to the US & it was held in customs for weeks, inspected my the fisheries department, then sent back to her - she had properly declared value & materials - so, yeah, there could be issues - I'd contact the country of import for specific paperwork required.
