Reliable Appraisals

With a Certified Gemologist Appraiser and a Master Valuer on staff, Mangan Jewelers can handle all of your appraisal needs. Appointments can be made to have your precious family heirlooms appraised while you wait. If you prefer, you may simply drop off the items for appraisal and return to pick them up later. Our expert appraisers have many years of experience in valuing both vintage and modern jewelry of all kinds. Both are graduate gemologists from the Gemological Institute of America (GIA), and both have studied valuation science as well as gemology.
