Yummy, packed with protein and energy. Great with bread or crackers, jelly or marshmallow fluff. What more could one want? How about diamonds? Peanut butter turned into diamonds would be like the cherry on an ice cream sundae.
One of the scientists at The Centre for Science and Extreme Conditions at Edinburgh University is helping to press peanut butter into diamonds. They use up to 5 million atmospheres of pressure to create the diamonds from any carbon-containing material, including peanut butter. The samples they have must be very small because the article notes that if they reach their goal of making metallic hydrogen they would need approximately 1/2 square inch pads to make enough to actually study.
For those who don't want to wait for created diamonds from peanut butter, I introduce cultured diamonds from Gemesis. I remember when this process was announced a few years ago. Lab created rubies, sapphires, emeralds, etc. have been around forever. Even though they are real gems with no flaws, they are grown in labs and considered inferior to the mined jewels. When someone finally developed a growing process for diamonds they recognized that the created diamonds might share the same fate. Instead of calling the diamonds created, they took a page from the cultured pearl handbook and used the term cultured. Everyone know that a cultured pearl is made with human intervention (a round particle is put into the oyster in order to get that nice round shape) and they are worth more than regular pearls. I don't know if they were ever able to mitigate the stigma of created gems.
