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 time received to the time shipped.

Return postage and insurance is added to all service fees. 
A $50 rush fee may apply to rush requests of 3 days or less.
