Just a really pretty three stranded  pearl like necklace on a connected neck closure. 
Assorted pale pinks, glossy champagne colored pearl beads, and assorted other beads really make this a great piece to compliment any decolletage.
A little wear to the beads - hardly noticable. 
The actual type of bead and pearl make up is unknown. 
I do know this is an oldie!
Shown on bodice for size/style idea. 
Has an old school hook and snag closure with Japan engraved. 
No magnetic properties to the necklace. 
Measures 15" PLUS another 3" to hook on to. 
This is a triple strand for an illusion of bigger to smaller strands - FYI.
