Hello Fernando,
I'm with David in that suasa usually doesn't patinate that heavily during active use. However, if not handled for longer periods and with varnish/grime/whatever accumulating, it still is a valid possibility.
There are some quite unusual alloys with low gold and/or silver contents in Asia. IMHO it would be interesting to have it tested: Just make sure the jeweller understands that you're looking for (very) low gold content as this will influence the testing approach. Better yet, results from modern XRF instruments should allow a full understanding of this unusual alloy.
Regardless of the alloy utilized, a nice , early example!
Regards,
Kai
