Jade Testing & Value Estimation Services & Fees

Mason-Kay has been engaged in the jadeite jade business since 1976. We offer full jadeite testing services to the trade, as well as value estimation services for appraisals to retailers and appraisers. In addition to the standard gemological tests (RI, SG, Optical spectroscopy) Mason-Kay is equipped with infrared spectroscopy to test for polymer impregnation ('B' jade).

We do not test or evaluate statuary, figurines or jade rough.

Please note that Mason-Kay's fees are not based on weight or value. Two additional stones within the same piece are tested at no additional charge and referenced on the report.

Mason-Kay provides value estimation services (current wholesale value at time of testing) for jadeite only; gold, diamonds or other side stones are neither evaluated nor tested. Items that are backed, encased or otherwise enclosed in metal may have to be removed for proper testing and value estimation. This is done only with customer's permission and at customer's risk and cost.

Standard turn-around time is 7-10 days (or less) from the date received.

A $50 rush fee may apply to requests of 3 days or less.

Return postage and insurance is added to all service fees.
