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?
1)Minimum investment is 1ETH
2)All diamonds will be natural diamonds, every single diamond will be certified by Gemological Institute of America (most trusted non profit organisation in the industry). thus ensuring that every diamond is natural and not treated, as GIA des not certify artificial or treated diamonds.
3) Vaults are located in Switzerland Freeport location, the centre for keeping diamonds and precious assets. It features top security and safety regulations. Furthermore there will be yearly vault audits by third party and those audit results will always will be available to investors to check so that everything is transparent and investments are secure.
4) Number of DIMND tokens will never exceed number of diamonds stored, emission and supply will be strictly limited so each DIMND token will always be represented by 0.001 carats.
5) In case investor will want to redeem DIMND tokens for diamonds we will ensure that he gets the diamonds via secure courier service, investors will be responsible to cover shipping cost, however due to small size and light weight of a package, the shipping cost will not be high at all, it will vary from around 50USD-150USD depending on the country of destination.
