All appraisals are done on-premises by our two Gemological Institute of America (GIA) Certified Diamond Graders, Michael Libero Jr. & Ashley Libero-Abate. Complimentary appraisals are done on all Libero Jewelers merchandise at the time of purchase. Additional jewelry can be appraised for a fee. Please contact Ashley Libero-Abate for details and to make an appraisal appointment. Libero Jewelers also recommends that you provide any gemological certifications, past appraisals, and/or original receipts at the time of the appraisal to ensure the most accurate appraisal value.
