I couldnt find any markings.

One necklace is 14 1/2" long but has a 2.5" extension.  The other is 14 1/2" long but can be adjusted down.

SORRY, I WOULD RATHER NOT BREAK UP THE SET.

Great condition.  EVERYTHING WORKS AS IT SHOULD ON BOTH.  I dont see any missing rhinestones in either necklace.  The one extension is missing two little pieces.
