Hm. This is an interesting one.... wish my Latin were up to the challenge. I find it woefully lacking, having last cracked a Latin text about 20 years ago, and then at the ungodly hour of 8am, and it was Church Latin too!

But what comes to mind is a mix of the latin:
Argent Aurum (heraldry?)

just thought of that old Girl Scout verse:
"Make new friends but keep the old/One is silver and the other gold."

My husband just blurted out: "Metal Vanity"

I'm sure more and better ideas will follow...but be sure to post what you eventually decide on!
