Pro Tip 1/3
Not Manufactured
Minerals come from the Earth directly, not made or altered by humans. The amethyst stone is a natural mineral, not a human-made product.
Pro Tip 2/3
Non-Living Matter
Minerals are inorganic, which means they do not have living cells. Unlike plants, a mineral like quartz doesn’t grow or require nutrients.
Pro Tip 3/3
