This week, I want to highlight the difference between crystals and stones, which is another question I hear often. Let me preface this by saying, it's not as cut and dry as you might think. Let's begin with this statement:
All crystals are minerals, but not all minerals are crystals, though all minerals are crystalline.
Take a minute to let that sink in. Every crystal you come across at the obvious macro level (such as in clear quartz points) is indeed a member of the mineral kingdom. Pure and simple.
Now when I say that, I am referring to the crystals you see in your local rock shop or metaphysical store. I am not referring to something like water crystals, a.k.a. snow, or sugar, which comes from sugar cane. That is a whole other debate in which we have to make further distinctions between crystals and minerals and minerals vs. mineraloids, etc. and so on. So don't go all smarty-pants on me. That doesn't necessarily apply here. I doubt your local metaphysical store is trying to sell you snow. If they are, maybe shop somewhere else.
And an even smaller group than that would be the mineraloids, those substances which are minerals in every way except one--they might come from an organic substance, like with amber, or they may be amorphous (non-crystalline) like obsidian.
So that being said, what are stones?
Did you notice my use of the word stone above when referring to rose quartz?
The word stone is typically used to describe two things: either minerals which are cryptocrystalline (meaning they don't look like crystals except under a microscope or by x-ray), or in regards to aggregates of minerals, which we learned in the last post are in fact rocks.
It's important to keep in mind that these words--crystals, rocks, and stones--are often used interchangeably and not in the strictest most scientific sense. So let's go over some examples.
