Problems: She wouldn't have the time to set up the guys in Antarctica (or any reason to) in just a couple months, That guy isn't her type (too old, not even from the same area of the globe), it probably cost her more money to set up all that stuff than the worth of the diamonds.
Money defies time Jon. With enough money people will JUMP and JUMP FAST for what you want them to "set up".
I didn't say she was riding the old guy. I'm saying it's a family heirloom or something along those lines. Just that it's SOMEHOW connected to her. But he was doing Nikki the ho-bag.

Those diamonds could be worth more than it costs, but even if it's not...revenge for conning and killing a grandpa or someone you cared about is MUCH greater in price.
