I was absolutely floored when I started seeing advertisements for 'chocolate' diamonds a few years back, and even more floored that people I knew just HAD to have them.

I had dealt with 'chocolate' diamonds for years, I currently have hundreds in my wood shop! My father works as a machinist, and brown, low-quality diamonds are their abrasive of choice for many jobs. They're (or rather, they were) super cheap because they were such low quality. I always swiped a handful when I visited him at work as a kid, because they made great pellets (they were exceptionally tiny and really hard) for my slingshot. I had a whole jug of them and just forgot about the things.

And now here we are.
