Clarity  enhanced diamonds can be a fantastic choice if you're looking for a good looking natural diamond in a lower price range. These are natural diamonds that have been enhanced by a process that fills in the natural feather type inclusions. The inclusions are still there, you just can't see them any longer. The process doesn't effect the color nor weight of the diamond.  The process is safe & permanent and usually is only reversed when the diamond is directly torched. In that event, the diamond can be retreated & restored to it's enhanced state.  Another way to look at this is that you're paying for a diamond with a lower clarity rating that actually looks like a higher clarity. Many clarity enhanced diamond suppliers offer lifetime warrantees for re-enhancement. Some clarity enhanced diamond suppliers offer third party certificates which are good for identification & insurance purposes, however the diamonds clarity rating is usually shown as the clarity AFTER the enhancement. The Yehuda Brand & the Oved Brand of enhanced diamonds offer lifetime warrantees.
