Don't be fooled by the other sites offering cheap quality chains. Ours have 5mm Genuine Cubic Zirconia diamond simulant stones bezel set by hand. Each link is 6mm in diameter. This chain is made of brass, and plated with real white gold.

The above picture shows 3 chains to represent the size difference between 4mm, 5mm, and 6mm you will not recieve all 3 chains :)
