Crypto backed by gemstones now thats would be cool
Yes, I agree. I've heard about cryptos being backed by Gold, but up to this point, there hasn't been a cryptocurrency which is backed by gemstones. That would be awesome, since you'd get to invest into Diamond, or other valuable gemstones without actually owning them. It would be some sort of a digital token that would live in a blockchain (either Ethereum or EOS) which can be exchanged to physical gemstones at any time or viceversa (similar to Digix DAO).
The problem with your plan is as soon as you try to sell the gemstone, you will have to sell it at a loss as "second hand" or you won't sell it. Buy it for a piece of jewlery for your significant other/yourself, but I don't think this is a good business plan.
Thanks for the tip! I've thought that gemstones were a good investment after all, since some of them are extremely rare (like Diamonds). What I've noticed is that depending on the color and size, will be the valuation of that specific gemstone. As far as I know, transparent diamonds are the most valuable (please correct me if I'm wrong), followed by other colors such as Yellow and Pink.
An online store or marketplace which would allow us to exchange crypto to gemstones would be ideal.
