Jade Services

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.
