Mason-Kay has been engaged in the jadeite jade business since 1976. We offer full jade testing services, as well as jade value assessment services. In addition to the standard gemological tests (RI, SG, Optical spectroscopy) Mason-Kay is equipped with infrared spectroscopy to test for impregnation ('B' jade).
We do not test or evaluate statuary, figurines or jade rough.
Jade Value Assessments can be for Retail Replacement Value (what one would have to pay to replace an item at retail) or Fair Market Value (what one would expect to receive for an item in today’s market). Jade Value Assessments are only provided for natural jadeite jade.

Jadeite Testing – We first test for material. If a piece is found to be jadeite, we then use standard spectroscopy to test for natural color & infrared spectroscopy to test for the existence of polymer impregnation.
Value Assessment – Mason-Kay assesses the value of the jade piece/s only. Mountings, diamonds and other side stones are neither tested nor evaluated. Value Assessments are made based on the market at the time of the assessment. Values are estimates and should not be construed as an offer to buy in the case of Fair Market Value, or a guarantee of availability in the case of Retail Replacement Value.

Mason-Kay provides jade value assessment services for jadeite only. Mountings, diamonds or other side stones are neither evaluated nor tested.

We suggest documenting your piece/s for yours and our protection in whichever way you can. Photos and measurements are good.

When received, if the measurements and/or weight are not what you list, we will contact you right away. You can of course check the measurements and weight when returned to you.
