It's pretty hard for me to figure too , esp w/o being able to have 'em in my mitts , but the craftsmanship of the medallions on the pieces sure have an asain touch to them , IMO , thru old & tired eyes tonight .
It would be nice to hear the 'ping' of each one .
I would have to say that these are perhaps 'fantasy' items , but do represent a a fancy style that has appeal with many folks .... saying that , items produced to appear as older more valued pieces are all over the markets , so getting fooled by items in which 'we' hope are the real thing is possible .
That's just my jaded guess / 2 cents .
I'd suggest going over a couple of your pieces from your cool little set with a loupe or 10x magnifyer & see what you can see .
