Rough cut?

SO and I are both very big on things that would be considered a "natural" lifestyle...humane/organic food, compost toilet, tiny house/cob house, solar energy, no medicine or vaccines, etc etc etc. Well, I have always hated flashy, shiny engagement rings... It's just a matter of personal taste, but 99% of ones I see I just think are horrendously ugly. We found out about a type of ring called "rough cut" or "raw" diamonds???? GORGEOUS! It has the "back to nature" vibe that I know and love, AND since they're unrefined they are generally loads cheaper! Thoughts??? This is DEFINITELY the type of ring I want
