The MasterValuer™ jewelry appraisal program does not support jewelry appraisals that claim gemstones or jewelry to be sold for the purpose of investment? This is not to say that said appraiser is not qualified or capable of appraising properly, it is to say that it is the opinion of MV that a larger percentage of this type "investment" gemstone is commonly questionable and we as an organization of jewelry appraisal professionals do not support this practice.

Please understand that a Registered MasterValuer™ who would advertise as a reseller of "investment stones" cannot use the RMV credential as any basis for said appraisal. This is a "buyer beware" announcement. For information, contact Dee Rouse Huth - 800-731-1122.
