Statement Choker Necklace of Ivory popular Shell and Freshwater Pearl

This Ivory shell and Freshwater Pearl necklace is collar length.
The popular double drilled spacer beads are raw cut aquamarine.
It is currently a 15" necklace that has an adjustable chain which extends an additional 3". I will be happy to make this necklace shorter, at N/C, or I can also make it longer, with a comparable chain, for a small additional fee.
