kinda interesting ladies necklace/earrings set?

Here's a little set I nearly missed, found wrapped up neatly in a plastic bag while dumping a large plastic binful of ladies clothes that nobody will ever wear again. OH...I says to myself, a little bag of jewelry, before sticking it in my pocket. When I unwrapped it later, here's what I gots?! ;-)

Nothing "old valuable fine jewelry" I'm certain by ANY means, but still a fun set to look at...? ;-) The earrings and pendant are all the same size, (1"L x 1/2"W) made of amber colored translucent plastic decorated with texured/filled in black 'graining' on their curved fronts, flat/undecorated on their backs, and wrapped in thin silvertone wire. The chain itself is 26" long, silvertone as well, which the pendant hangs free upon, captive between two small clusters of beads. (about 1"L ea, and 6" apart) Kinda difficult to see but the largest of each of those clusters is actually a reddish translucent color.

There is only one marking I find on it, on the metal 'blade' part of its spring clasp. It is not well stamped and try as I might I can't completely read it all except for the last two letters that do look to be "EA", my bet would be the first three are "KOR". Dunno if that'd mean the whole thing came from there or just the clasp assembly itself if this is actually some kinda 'artisan/craft fair' made set vs. just cheap 'dollar store' material.
