Never deal with sellers that are unwilling to offer certification or say it is not necessary.

Make comparisons of visuals with descriptions by the seller.

How to Avoid:

Request some recording or details as to the origin of the gemstone.
Select the sellers who are ethical in sourcing and fair trade.
