green chain 

a fake (expensive) chain worn to give the appearance of wealth while actually on a budget

named after the greenish tint that may be left on the skin by jewelry made of/containing more of a less expensive, but more reactive element like nickel, copper, or zinc, which can react with chemicals from the skin to stain it. This is in contrast to jewelry made from less reactive, but more expensive alloys or pure precious metals (gold, silver, platinum, palladium), which don't react to skin oils/sweat as easily.

green chain 

A green chain, in a sawmill, is the chain that carries processed boards that are ready to be packed.

Green chains are typically associated with manliness, as only true men can be successful on the chain.

Green chains are places for champions.

"The boards, having finished their journey, travled down the green chain while waiting to be packed."
