There are several common ones that all polish up pretty shiny, making it almost impossible to tell them apart; both physically & sometimes even energetically.
But there are slight differences & I’m going to tell you what to look for right here.
I’m going to focus on the 5 most common ones:
As most black stones usually are, all 5 of these are considered to generally be energetically grounding, protective & usually resonating well with either the Earth Star Chakra or Root Chakra.
Now let’s get into the subtle differences…
I’ve divided the stones into 2 sub-groups of “non-mineral” & “mineral”.
The non-minerals, although usually lumped in with the rest of the crystals, are not technically minerals, because they don’t have 1 very important aspect that all minerals must have: a crystalline atomic matrix, a repeating geometric pattern among their atoms.
Jet is not a crystal/mineral…it lacks a crystalline structure. Why? Because it originates from a once living thing; a tree. So it’s organic & not a mineral at all. It’s actually considered to be coal & forms when pieces of wood from a tree get buried in sediment and get “coalified”. This is a process that took place a looooong time ago; we’re talking literal Jurassic Period here.
Under a microscope you can actually see the old tree’s cell walls! Pretty cool.
Because of this cell-wall kind of structure it’s very lightweight & that’s one of your clues when comparing it to their black stones. Pick it up & compare its weight in your hands. It almost feels like plastic, it’s so light.
Although it’s usually pretty dull in its raw form, it can be polished up to a high luster & be quite shiny (as you can see in my above picture where its shown compared to other black stones). Another tell-tale clue is that jet can sort of look a bit dark-silvery-metallic (sort of like a really dark hematite).
Energetically, jet is known to be safely grounding + purifying while also being protective…in a gentle, non-forceful way.
Obsidian, another non-mineral, is a volcanic glass, born literally of forceful fiery energy.
Birthed in a volcanic eruption when molten lava spews up from a volcano, obsidian flies out & then cools quickly once it touches the cooler land or much cooler water, sometimes forming teeny bubbles within…and cooling much too quickly for its atoms to arrange themselves in the necessary crystalline atomic structure to qualify as a mineral. This makes it a glass & not a crystal.
So your clue here is that all obsidian (not just the black variety) will be very smooth, shiny & glassy-looking.
If you’re looking at a rough natural piece as in my above photo (where I’m comparing all of these black stones), you’ll notice that obsidian usually has a conchoidal fracture: a geeky-geo-term for a curved break off point when the obsidian gets chipped away.
Can you see that conchoidal fracture in the below pic?
If you’re comparing obsidian to onyx (2 that are quite often confused), obsidian will be the lighter weight of the 2 because it’s less dense than onyx (due to the lack of crystalline structure & interior air bubbles) and can even be translucent in spots if you hold it up to the light…something really hard to capture in a photo for me…but I tried in the below photo. See how the sunlight can shine through it & you can even see some layering on the bottom right?
Remember that obsidian is volcanic glass so it has a direct fiery energy to it. Perhaps due to how it originates, I feel it’s not gentle in its ways at all. Generally, it’s a pretty powerful stone.
CAUTION: If you feel that you’re very emotionally fragile or vulnerable, I recommend you try another stone choice instead.
Now this may not be true for everyone, so it’s not a blanket statement.
You really need to work with it yourself to know EXACTLY how it will affect you.
Obsidian is great for quick & powerful grounding, cleansing away deep or stubborn negative feelings & when you need POWERFUL psychic protection. Again, I do caution people to only use it when you need a really powerful punch & not to work with it for too long…unless you already know that you can work with it safely with no adverse effects.
Apache Tear is really a sub-group or type of obsidian; essentially the same stone, both made of volcanic glass and black in color. However, Apache Tears are black obsidian that formed by being thrown up into the air giving them a much less glassy & more rough appearance.
Whereas black obsidian is known to be a very powerful stone, Apache Tears are gentler in their energy & good for less forceful emotional cleansing like working through grief… because it’s much lighter & gentler in its energy it’s great for emotional clearing while also being grounding & protective.
These next stones are the real-deal minerals. All minerals have a crystalline structure at the atomic level where their atoms are stacked in a precise repeating geometric pattern. So these guys are more stable & can more efficiently influence your energetic field.
When you hold a piece of onyx, one thing you’ll note is the density & “weighti-ness” of it. Between 2 similar sized pieces of onyx & obsidian…which can look very similar, the onyx will be heavier because it has an actual crystalline structure, whereas obsidian does not…with its random molecules & air bubbles.
Onyx tends to have a slightly duller finish, but can polish up to be quite glassy! So don’t rely on that alone. Onyx may also have some banding & white-ish or grey-ish spots, but usually no translucency.
Onyx, being a true mineral, does indeed have that crystalline structure at the atomic level. Why? Well, it had the time to form one, growing slowly underground, as crystals do.
Onyx’ energy for me, while protective is more about grounding & strengthening. It’s also wonderful for boosting your willpower & discipline
Black tourmaline is a fav of mine & 1 of the crystals I use in my sacred grounding trio.
In it’s natural form (as seen below), black tourmaline is hard to confuse with the others I’ve listed here.
But when it’s tumbled it can be hard to pick out because it polishes up relatively well…but usually not perfectly & that’s how I usually tell it from the others. You’ll often see some divots & possibly some rust from its iron content too.
Energetically, black tourmaline is a go-to negativity neutralizer for me. Because it has piezoelectric & pyroelectric proprieties it’s able to transduce energy quite effectively! If you’re looking for a great crystal for protection & purification that isn’t too intense…this is the one.
So there you are.
I hope you find this info to a be a helpful resource that you’ll be able to refer back to when needed!
Can you tell the difference now? Do you have these stones in your crystal collection and now you know how to identify them on the fly? Talk to me in the Comments below! I’d love to hear about your favorite black crystal.
after reading this, now I'm not sure what I have.....I'm thinking between onyx or obsidian now...
