where:
- can be calcium, sodium, potassium, or (□) vacant
- can be lithium, magnesium, iron2+, iron3+, manganese2+, zinc, aluminum, chromium3+, vanadium3+, titanium4+, or (□) vacant
- can be magnesium, aluminum, iron3+, chromium3+, vanadium3+
- can be silicon, aluminum, or boron
- can be a hydroxide ion, or oxygen
- can be a hydroxide ion, fluorine, or oxygen
Different permuations can yield crystals of different colors, and some of those permutations are common-enough to have names of their own. For example, a tourmaline crystal that has the chemical permutation NaMg3Al6Si6O18(BO3)3(OH)3OH is typically brown in color and is called "Dravite," whereas a tourmaline crystal that is composed of □(LiAl2)Al6Si6O18(BO3)3(OH)3OH [where '□' indicates a vacancy in the 'X' position] is pink to light-tan in color and is called "Rossmanite." The most common tourmaline is the one called "Schorl" with a chemical formula NaFe2+3Al6Si6O18(BO3)3(OH)3OH that makes it black in color.

These are beautiful photos of tourmaline.
it just reminded me of when I was in college. I was given an assignment to pick different kinds of rocks.
You did some great research here too though, well done!
I like the structure how they come out, forming a cooler looking joining. I eventually want to build a collection of gems/minerals.
Some people collect comic books but you collect minerals which is fascinating. I should have paid more attention in chemistry back then. Can they be made into jewelry?
Yes, tourmaline is sometimes cut into gemstones for rings, necklaces, and earrings!
Wow very good I follow you follow me back thanks in advance
This is called spamming. It's not right
whoa these are gorgeous, first time I've seen it ✨
Wow... this is pretty interesting! Thanks for sharing!
What chakra(s) is this most beneficial for?
@dynamicgreentk ~ Personally, I pair stones to chakras by color. So, a blue tourmaline would align with the energies of the throat chakra, green with the heart chakra, and so forth. Black stones/crystals are good for repeling negativity, or could possibly align with the either the base or root chakras.
Oooohhhh.... I am frantically preparing for vacation. Among other things, we will be stopping in Arkansas to freshen our supply of crystals. I DO love rocks, and that little cluster is GORGEOUS!
Some of my crystals have been purchased on the Internet from ArkansasCrystalWorks, which is near Ft. Smith, Arkansas! It is run by a really cool lady who digs most of the crystals she sells! When you freshen your supply, please consider photographing them and tag me!
Interesting mineral facts :) does tourmaline consider as rare stone?
@kimzwarch ~ Tourmaline is considered one of the "semi-precious" stones. Not as highly valued as diamonds, rubies, sapphires, and emeralds, but in the same category as topaz, turquoise, lapis lazuli, and others!
I see, interesting to learn more about these stones :) Thanks for the info.
