Conflict Free Diamonds???

OK, so since I am too busy to post photos - I wanted to share this cool concept with all those engaged couples out there. This company, Brilliant Earth, promises "conflict free diamond jewelry." I can't vouch for them as I just learned about them myself, but I think it is a nice concept (even if it is just a concept.) They seem to have great reviews online. If anyone out there has any experience with this company or other companies like this, please let me know!
