Your final option should be a jewelry store. It is
vital that you not let your diamond out of your sight while in the jewelry
store - you might find that the diamond you
walked in with is not the same diamond that you walk out with! The
jeweler will try to tell you that your diamond is of poor quality or low
weight. Inevitably, there will be some problem with the diamond. This is where
your appraisal and/or certificate will come in handy.
If the jeweler is fair, they
will offer you between 60% and 80% of the value of the Rapaport Value. Do not accept anything less than
this. Again, do not let the diamond out of your sight until you have been paid
for it.
