What to consider before purchasing a Natural  Blue Sapphire

What to consider before purchasing a Natural Blue Sapphire

Recently I had a client request help in sourcing a fairly expensive blue sapphire.  The first question he had was in regards to what part of the world the stone would be sourced from, and what types of verification would be supplied.  His concern was very common and well justified, as the price of a blue sapphire is often reflected by the region in which it was sourced, also known as it's origin.
