Part of the Interlink Collection, these unusual link necklaces are made of silver links with 9ct gold beads.
The main image shows the lighter version but if you click the second image then you can see the two different weights of necklace side by side.
The links in the fine one are each one inch long and are mounted with 4mm gold beads, so 16 links is 16″ and so on. You can order this one by the link to make up any length you like.
The heavier version uses 5mm gold beads. With this one, 14 links will take you to just over 16″ and 15 links just under 18″.
