Here’s a comparison of the amphibole, the unusuable garnet, and the nice garnet I’m going to use for dating. When picking garnet you want to make sure the grains don’t have a lot of inclusions or alteration, which makes them orange and opaque. The nice garnets (the pile at the top) should be somewhat clear and pink. (Syros, Greece).
Malachite is green because of the copper it contains. In fact, malachite was one of the first minerals used as a source of copper until larger veins of actual copper ore were found! Since malachite is formed by the interactions between copper minerals and carbonated water or limestone, it tends to form by precipitating, causing the beautiful banding that you see in pieces like this:
I do not have a solid, jewelry-quality piece like the above picture, but I do have a piece of fibrous malachite!
Malachite has a very variable crystal habit because of how it forms as a variation of copper minerals, so both the stalagmitic, layered variation, and the tiny needle-like fibers are common forms. Fibrous malachite has a beautiful velvet shine, and the structures look almost feathered!
Here are some pictures of the piece that I have:
Very rarely, it can also form as individual crystals!
