I would like to send a rock to someone, hopefully a rock that I have in my region but that she doesn't have there. But I don't know very much about rocks or geology.

I would like to send a thank-you gift to someone who lives on the island of Lewis in the Hebrides. She is passionately interested in the natural world, and I think she would enjoy a "piece" of our region (the Colorado Rocky Mountains) a lot more than a box of chocolates or the like. But I can't figure out what we have, rock-wise, that would be interesting or new to her.
Cursory research seems to indicate that Lewis (and the Hebrides in general) is mostly made up of very, very old gneiss. Our Rocky Mountains have old rocks, too, that only became exposed much more recently. But "gneiss" seems to be a generic term for many kinds of rocks, and I can't tell if our red sandstone—the most distinctive thing I can think of—is a kind of gneiss, too.
Basically, if you know rocks, can you tell me if there is anything particularly interesting or unique in the Rocky Mountains that would delight someone who lived in another part of the world? Or maybe a small common fossil or something? The recipient is not a geologist or scientist, and I'm not trying to impress her or anything—just to send her something she would like and would take as a token of appreciation and respect.
[I don't know yet how I will get some, if you can just, like, pick up a broken-off bit and carry it away (didn't Ian McEwan get in trouble for taking a pebble from Chesil Beach?) or if I need to buy it from someone. Ideas on that would be great, too!]
