What is the value of a stolen gold necklace that must be repaid six years after the theft and repentance? Is it its value at the time of the theft, at the time of completion, or its current value?

Theft is one of the major sins, and repentance from it is not complete until the rights are returned to their owners, for the Prophet, peace and blessings be upon him, said: "The hand is responsible for what it took until it returns it." The stolen item must be returned if it exists, or its value if it has perished, and the consideration is the value of the item on the day of the theft.
