You are selling real or artificial diamonds in ICO? If you could guarantee the safety of your vault where you are keeping them and prove they are not artificially produced in labs, It would help with noob investors like me

Do they cut diamond with diamond or use something else? because diamond is the hardest thing in the world.
This is valid question how to prove these diamonds are real and have good value to invest in them. When the details will be out for shipping procedure what it will be cost and how you will make this process to deliver the original product to a person?
