A lot of people in Pk assume that rare gems and fine jewelry is something you just waltz into a store, lay down some cold cash and walk out with it.
With FMCG that sounds great! - with rare gems, precious metals, historic artefacts, art etc. The value of the item is directly tied to its legal status.
There is a trail of paperwork tied to gems and precious stones. without it, its as good as stolen.
