“Mr. Naughter,
Thank you very much for the appraisal you sent to me today on three pieces of jewelry that I submitted to Wendy Peluso at Northeastern Fine Jewelry. I have no basis for comparison but I was very impressed with what appeared to be a very thorough and complete appraisal with lots of backup information provided for the client who is unfamiliar with jewelry.”

Thank you so much for your quick response and a very comprehensive appraisal. My husband will be in tomorrow or Thursday to pick up my ring. Very Impressive! Thanks again”
