This is true because each location has its own character and their own value and by getting this information, the buyer will already have a very good idea on the desirability of the stone. Vietnam gems, especially Vietnamese rubies are not as rich in color or clarity as Sri Lanka or Burmese rubies but quality is acceptable and price is competitive.
