Lapidary artists can do amazing things with gems — making them reflect light and look as if they glow from within. But, there is something to be said for the use of raw, natural stones.
Here are some fine examples of artists finding beauty in the stone more or less as nature intended:

As someone who has always made things — paintings, assemblages, and now jewelry — I think restraint and dealing with ambiguity is more difficult than attempted perfection. Using raw stones, which I’ve experimented with lately, is like that. They’ve got their own ideas. They tell you exactly how they will allow themselves to be used. It would be nice if that gorgeous, shiny thing were even and not rough on that one side — but it isn’t — and that’s the beauty of it. Incorporating raw stones into one’s jewelry is a different kind of craftsmanship. It’s the craftsmanship of subtlety and allowing yourself to simply frame something that is just fine the way it is.
