This is a 4.8MM Herringbone Necklace.  Available in 2 sizes with a lobster claw clasp.

24KT gold overlay.

Our chains and bracelets are made from real gold over a brass core.  Brass is a strong, durable metal that is perfect for overlay jewelry.  Our items have less than 1% nickel in them, so allergic reactions are rare.

When buying our jewelry, be sure to match the same karat charms with the same karat overlay chains, if you want the colors to match.  Same goes with all other denominations.  Color shades are different with each gold karat.
