Why Jewelry Appraisals Matter
How important is it to have your jewelry appraised? It is crucial to have a valid appraisal for your valuable jewelry.
If you are going to insure your jewelry you must have one.

What is a Jewelry Appraisal
An appraisal is a judgement of the value of a specific piece of jewelry on a specific date in a specific condition.
Appraisals Should Be Done By a Qualified Appraiser
A good jeweler who has worked hard to earn the prestigious credentials as a graduate gemologist is still not by any means a jewelry appraiser or someone qualified to assess and/or purchase diamonds on your behalf.
