I have access to Top Dollar Diamonds at price beneath market value. All cuts, size, color, clarity and price. Everything appreciated and certified by gemologist with paper.
After much research, no similar vendor in Darknet. Is there market for diamonds in darknet? Which market would be best to be diamond vendor, or is darknet just for drugs and guns?
sorry if this violates rules of subreddit.
There's really no market that's good for just this, so you'll have to make your decision based on the standard factors that any new vendor considers. Check out the marketplace comparison chart and pay attention to vendor fees, required FE, if multisig is supported, etc.: https://vault43.org/chart.php
As for your product, I'd be willing to buy a nice little chunk, but since the vast majority of buyers won't make the diamond into anything, it'll have to be cheap. I just like shiny things.
Also, you should make diamond bongs.
