We've tried to find out more about this piece and we've been told it is handmade, possibly from India or China.  It was acquired in an estate sale and had no information accompanying it. 

The necklace itself measures about 39",  The pendant measures 4" by 3.74".  It weighs over 15 ounces with the pendant weighing in at about 9 oz (we cannot remove it so this is our best guess).  The back of the pendant is carved in silver and the clasp is hand made with small decorations.  The lowest stone on the pendant is a tiger eye, carved into an eye with a carved stone border around the base of it, surrounded by silver.  There is another Tiger Eye above, with 2 stones to either side, all with a silver surround.  The pendant is held onto the necklace via a sterling silver bar, with 3 stones inlaid, 2 matching the stones beneath and another of turquoise.  On either side of the bar there is a turquoise piece, carved stone pieces and wood pieces all the way up the necklace. There are four wooden beads on the piece, each intricately hand carved.  Two appear to be dragons or fish, while the other two vines and leaves.
