Gunmetal doesn't seem quite as black in the chain, as it does on smaller items.
Gunmetal chain works surprisingly well mixed with antiqued silver.
We have some opened spools of gunmetal chain we used on
example jewelry recently. On your next order, perhaps ask the sales staff to send a couple inches of some of these chain pieces to see if the color works for you. (You can put a note like this in the comments section of an online store order, but I think it will work better if you give us a call at 1-800-366-2156.)
