With a Lot of Value involved, you want to make a educated Decision!
I would recommend you learn a bit about Diamonds before making any purchase Decisions!
The GIA Laboratory, a "Not for profit Organisation"
offers some good general Information about Diamonds.
I think this is a very good starting Point!
