Peanut butter is a favorite breakfast and snack for many Americans, and not only for them. The food paste, made primarily from ground roasted peanuts, with or without added oil, was first used by the Pre-Columbian peoples of Mexico, who used it as a base for various "moles", meaning sauces.
Now, a team of scientists presented the most recent and spectacular use of peanut butter ever. They have proven it's possible to turn the common peanut butter into the most expensive gems in the world, diamonds.

However, diamonds made from peanut butter are generally very small. The largest produced to date are no bigger than sesame seeds. Also, unlike diamonds formed naturally, these synthetic diamonds capture nitrogen from the air, giving them a greenish or yellowish hue. One look at these peanut butter diamonds, and it would be clear they are not quite the real thing.
