Two divots will be filled with moon-glo epoxy so they'll glow in the dark, the others (dimples) will have an anodized finish in them similar to the Blackwood Skirmish. That's what initially inspired me to do that sort of thing on my knives.
Now that you mention it I've got a bunch of Garnets that my GF and I dug a couple months ago, Idk if you've ever heard of this but there's an open garnet seam off one of the local highway's in Garner NC, and one can park on the side of the road and all the rocks are filled with Garnets. Most are about the right size, but they're kind of a muddy brown and I'm not sure how much I like that color. I'm still looking at options, worse comes to worse I'll leave the holes there like I do on a lot of my knives to add some extra grip.
