A young woman travelling on a plane finds herself sitting next to an older woman wearing a huge diamond ring. It's so intriguing to her that she has to ask about it.
"That's a gorgeous ring you have on. That center diamond is the biggest one I've ever seen."
The old woman perks up a bit. "Why, Thank you. That large middle diamond is actually known as the Plotnik Diamond. I'm not sure if you've ever heard of it, but the Plotnik Diamond actually comes with a curse"
The young woman says, "Wow, a curse! That sounds so romantic"
The old woman frowned a bit then said, "If you knew the curse, you wouldn't think it was so romantic"
"Why? What is the Plotnik curse?
"Mr. Plotnik!"
