all those little reddish orange yellowy specks and streaks in the quartz, that's iron Sunshine.

Iron won't hurt you, your body actually needs it in limited quantities.

difficult to find a large piece of quartz without streaks of iron. The amber piece is loaded with it.

looks exactly like the quartz in our backyard, except ours is not polished. We bought a rock tumbler a few years back, takes forever to run though, a real project. I had a big chunk on the porch, don;t see it there anymore.. probably it's in the flowers. Maybe if I get inspired later I will snap a photo and show you what it looks like unpolished, simply cracked in half.

same exact colors as yours though. how much did they charge you for those?
