It doesn't make sense at all if you backed your coins with diamonds because diamonds have never been a currency in the past. unlike gold and silver, diamond is a kind of jewelry that its style will determine its price. you guys have a few details with your project and mostly this kind of thing will be buried if not back up with strong arguments or references. Diamonds eh? I've heard parrots and Pig before but diamonds, maybe some kind of innovations that will make the crypto industries evolve into something new.
