Expert Witness Services in Jewelry Valuation
When jewelry valuation becomes a matter of litigation, an expert witness with recognized credentials and documented methodology can make a significant difference. With nearly 38 years of industry experience, credentials from the GIA, NAJA, and AGS, and extensive appraisal experience, I am qualified to provide expert testimony in matters involving jewelry valuation, gemstone identification, and appraisal standards.
Services include written expert reports, deposition testimony, and courtroom testimony. Each engagement is approached with objectivity, thoroughness, and a commitment to accuracy — regardless of which party retains my services.
My opinions are based on professional gemological examination, current market data, and established appraisal methodology. I am prepared to explain complex gemological and valuation concepts clearly and credibly to judges, juries, and opposing counsel.
