Looks like you have done searching for the void in the market and you came to a conclusion that there is no project backed by diamond . I understand you curiosity about making your idea successful, digital token can be created by anyone as it is open source and what makes it valuable is when investors are willing to trade, you can see thousands of worthless tokens and it does not mean anything.

The project you are talking about is not easy unless you have some contacts in Antwerp because it is the diamond capital of the world .
