Usually when you offer something (jewelry, property, etc) up for collateral, it is in "hawk". Possessor can be a bank, a pawn shop, an impound lot, etc; but is usually limited to legal matters.
You can get the item "out of hawk" by paying the money back, or filling the contract out.
"I need 50$ to get boardwalk out of hawk"
"I hawked my wedding ring to the pawn shop for 200$"
