Bits of Sea Shells: Beach Ready Necklace and Bracelet Set Vintage

This set is from an estate sale; maybe a memory from a long ago island vacation?  It would look great with your casual clothes or bathing suit, whether at poolside or island hopping.  

The necklace is 30" long, the bracelet is 8".  The shell pieces (possibly Mother of Pearl?) have a lovely rainbow opalescence.  Each has been smoothed & buffed and a hole drilled in the middle.  They are connected with a tough plastic line (fishing line?) and separated from each other with tiny glass beads.

You can see how the necklace & bracelet are attached-BUT- the loop they left on the bracelet is awfully snug for the shell that is supposed to go through it.  I didn't want to force it, so decided to sell the necklace & throw in the bracelet for free.

This is a fun set & I have not attempted to clean it.

Time period is estimated to be from the 1960's or '70's.
