blue and white koi beads on knotted blue silk

hi...i won an auction and this pretty blue and white necklace is one of the many items i got...i've looked on the internet and all i have been able to find is round blue and white beaded necklaces with a different pattern...i am hoping a savy vintage jewelry collector will have some info they would like to share with me about this very pretty necklace...lol...i like to make my own bracelets etc from vintage jewelry and i was about to tear this one apart until i realized it was on knotted blue silk...it was too late for the red cloisonne beaded necklace tho...i tore that one up the day i got it home...it wasn't until later that i found out that it was antique....thanks for looking and any comments are always welcome...love this site!
