Five disciplines.
One uncompromising standard.
Each discipline is led by a senior specialist with decades of trade experience. Items are graded by two independents and reconciled by a third — a system we have used unchanged since 2014. The grade, the certificate and the holder are unified under one house standard.

House Standard
Tooled for one purpose.
Every specialist works from a Xene bench, fitted with our own loupe, calibrated brass weights, anti-static tweezers and a dedicated handheld XRF spectrometer. Tools are inventoried twice daily; calibration is logged and certified quarterly.
Each item passes the same bench, the same lights, the same eyes and the same lens. The result is a grade you can trust to mean the same thing today as in a decade's time.
