ok so here's how its done.

- You will need a hacksaw or some pliers.
- You will need to locate the power cable that leads into the jewelry store from behind it. Cut the cable
- Wait till the store is closed.
- have at it.

What I'm working on regarding this heist.
- Once completed you get an achievement. This is important because it unlocks the bank heist coming later.
- Once completed you will be able to sell the jewelry for money. This is important because you can use that money later for other things.

Currently the money doesn't do you any good. Just needed to make sure the system was there for me to be able to add other features and uses for the money.
