If You See These Patterns in a Rock, Congratulations — There's a Diamond Inside

Rocks tell you things before you ever break them open. The problem is that almost nobody is taught what to look for, so the signs get walked over every single day. In this video you'll learn the surface patterns that tell you a rock came from diamond-bearing ground: what the rusty orange staining means, why the fresh break underneath looks nothing like the outside, the rounded red grains that travel alongside diamonds, and how to follow those signs back upstream to where they came from. Stay to the end — the last pattern is the one almost nobody knows. Have you seen any of these on a rock before? Tell me in the comments.
