Green Aventurine

Quartzite with fuchsite (chromium mica) inclusions

It began as plain sand on a seabed. Buried, pressed and cooked, the grains welded into one hard rock, and flecks of green mica got caught inside. Tilt it and those flecks wink at you. That is all the sparkle is. The odd part is the name. It was borrowed from a glass an Italian maker spilled by accident, so the stone is named after a copy of itself. Blue and red aventurine is nearly always dyed quartzite. Green is the one they left alone. You have been waiting on a break and telling nobody, because saying it out loud would make the wanting real. Put it in the jacket you actually wear.

People carry it for abundance, calm and self-love. Tradition attaches it to the element earth, the heart chakra, Venus. It is most often given to Taurus, Virgo, Libra. It measures 6.5-7 on the Mohs scale.

What it is confused with

Chrysoprase, jadeite jade, green goldstone, serpentine, amazonite

Opaque green with a glittery shimmer the trade calls aventurescence, thrown by thousands of tiny reflective mica platelets. Tilt it under a lamp and separate points of light flash on and off across the surface. The green is mottled and slightly grainy rather than smooth. A hand lens shows individual green flakes suspended in a grey quartz groundmass. Broken surfaces are grainy and sugary rather than curved, because this is a rock and not a single crystal.

How to tell

Put a 10x loupe on the sparkle. Aventurine sparkles from green mica flakes of uneven shape and size. Green goldstone sparkles from a dense, uniform cloud of identical copper-chrome specks in transparent glass, with visible bubbles. Aventurine also scratches glass, and it is opaque with a grainy texture.

Natural green aventurine is untreated. Blue and red aventurine is often dyed quartzite. Green goldstone is a manufactured glass sold on the same shelf.

What it means

The moon is in Sagittarius today, so this is the Sagittarius read.

You were also on your own the one time being careful would have helped.

Shops dye grey quartzite blue and red and sell it as aventurine. They stock green goldstone too, which is glass, right beside the real green.

The green one is untreated. Its name still came from a Venetian glass that got spilled by accident, which is a joke the trade never explains.

Sagittarius, you got pressed into something solid and the bright part of you is what never welded shut.

Adults spent your childhood listing what you could not do, and being wrong nearly every time. So you stopped believing anybody who told you to be careful.

That is why you are brave. You were also on your own the one time being careful would have helped. You have never said so.

Check the label. Then do the reckless thing anyway.

Green Aventurine for every sign

AriesYou learned that being seen and being interested were the same thing.

Underneath the name it is sandstone that got cooked. Old seabed sand, buried and pressed until the grains welded into one hard rock, with flakes of green mica caught inside.

The sparkle is only those flakes catching light. Blue and red aventurine is usually dyed quartzite. Green is the one they left alone.

Aries, you were pressed into being the strong one and nobody has released you from it.

You got noticed for beginnings when you were young, and nobody stayed to watch the slow part. You learned that being seen and being interested were the same thing.

Now you drop good work at the moment it goes quiet, and you call it losing interest, and it is not that.

Nothing about this welded fast. It took the whole weight of a seabed.

TaurusYou handed money over once for something that was mostly a story.

Tilt it towards a window and the green flecks wink, then go dull, then wink again. Those are mica flakes trapped when sand welded into rock on an old seabed.

Green aventurine is untreated. The blue and red trays beside it are usually dyed quartzite, and nobody in the shop will mention it.

Taurus, you learned not to trust anything cheap that shines, and you learned it the hard way.

You handed money over once for something that was mostly a story. You did not argue about it. You went home and quietly rewrote the rules.

Now everything good has to stand outside and wait, and one or two of them stopped waiting.

This one is what it looks like. Put it in the jacket you actually wear.

GeminiSomeone asked how work is going and you did four minutes of material.

Blue aventurine and red aventurine are nearly always dyed quartzite. Green is not dyed, which makes it the plain one on a shelf full of improved neighbours.

Even the name is borrowed. It came from a Venetian glass spilled by accident, so the rock ended up named after a copy of itself.

Gemini, you call it luck because saying you worked for it feels like bragging.

Being quick got you liked in a house where being ordinary got you nothing. So the plain sentence began to feel like standing there with no coat on.

Someone asked how work is going and you did four minutes of material. The real answer was two words long.

Try the two words on somebody this week.

CancerYou can tell from the hallway what kind of evening it is going to be.

Sand lay on a seabed, got buried, and was pressed and heated until every grain welded to its neighbours. Flakes of green mica were caught in the middle of that and never got out.

Nothing was added later. Green aventurine reaches you exactly as it formed, which the dyed blue version cannot say.

Cancer, you got welded to your family so early that you cannot tell where you stop.

Somebody at home leaned on you before you were big enough to be leaned on, and you managed it, and everybody carried on as normal.

You can tell from the hallway what kind of evening it is going to be. You have never told a single person how tiring that is.

It welded slowly. So did you.

LeoYou kept paying that rent long after anybody was charging it.

Hold it in your palm under a lamp and turn your wrist. The green flecks light up one at a time, uneven, different sizes, which is how you know it is rock and not glass.

Green goldstone sits next to it in most shops. That one is manufactured glass with copper in it, and its sparkle is perfectly even.

Leo, the uneven days are the proof that you are a person and not a performance.

You were the bright one, the easy one, the one who made things nice, and it earned you a place. You kept paying that rent long after anybody was charging it.

The night ends and you know exactly how everyone else is. Nobody asked you, and you would not have known what to say.

Uneven sparkle is the honest kind.

VirgoYou will fix everybody's problem before you will name one of your own.

Call it what it is. Quartzite, which is sand welded into stone, carrying flakes of chromium mica that give it the green.

The name is not even its own. It was taken from a Venetian glass a maker spilled by accident, so a rock ended up named after an imitation.

Virgo, you were pressed into something useful and nobody asked you first.

Somebody in your house praised you for being no trouble. You were about seven, and you built a whole person on it.

Being no trouble means never needing anything out loud. You will fix everybody's problem before you will name one of your own.

Name one tonight. Small is fine.

LibraYou decided then that you would never be the one who did that.

Aventurine is hard, close to seven, and it takes water and daily wear without complaint. The mica flakes are locked inside, so nothing rubs off.

What it does not survive is the shelf. Sitting beside dyed blue quartzite and green glass, it gets treated as one more shiny thing.

Libra, nothing ever rubs off on the people near you, because you decided young to hold your own bad days.

One wrong sentence at a table when you were small changed the whole night for everyone. You decided then that you would never be the one who did that.

So you answer in a way that cannot start anything, and by now you honestly do not know which of the options you wanted.

Pick one thing today for no reason except wanting it.

ScorpioYou have never once been sure that anybody has met you.

Sand on an old seabed was buried, pressed and heated until it became one hard rock. Green mica got trapped in the middle of that and is still in there.

It is untreated, which is more than the blue and red aventurine can say. Those are dyed quartzite.

Scorpio, you keep the whole rock at home and send out the part that catches the light.

You were being honest and you were young, and their face did something you can still picture. After that you kept the honest one at home and sent a smaller one out.

The smaller one is liked everywhere. You have never once been sure that anybody has met you.

Nothing was taken out of this rock to make it sell.

SagittariusYou were also on your own the one time being careful would have helped.

Shops dye grey quartzite blue and red and sell it as aventurine. They stock green goldstone too, which is glass, right beside the real green.

The green one is untreated. Its name still came from a Venetian glass that got spilled by accident, which is a joke the trade never explains.

Sagittarius, you got pressed into something solid and the bright part of you is what never welded shut.

Adults spent your childhood listing what you could not do, and being wrong nearly every time. So you stopped believing anybody who told you to be careful.

That is why you are brave. You were also on your own the one time being careful would have helped. You have never said so.

Check the label. Then do the reckless thing anyway.

CapricornThere is a year you never mention that you got a whole family through.

Look at the flecks under a lamp. Different sizes, scattered unevenly, some bright and some barely there, because sand does not organise itself.

Green goldstone is the even one. That is glass, made on purpose, and it sits in the same tray at the same price.

Capricorn, you think the unevenness in you is a mistake rather than the proof.

You were praised for coping before you were old enough to know there was another option, and coping has been the whole method ever since. Rest gets filed under waste.

There is a year you never mention that you got a whole family through. You count it as a gap in your career.

It was not a gap.

AquariusYou cannot tell one person what you wanted this week.

It is sand that got buried and cooked into one hard rock, with green mica caught in it. That is the whole mechanism.

The name is on loan from glass. A Venetian maker spilled copper into a melt by accident, the effect got called aventurine, and the rock took the name afterwards.

Aquarius, the best thing about you came out of an accident and you have been taking careful credit for it ever since.

Somebody made you feel strange for the way your head worked, early on, and you handled it by watching from just outside. It was a good solution at eleven.

You can explain anybody's family in five minutes. You cannot tell one person what you wanted this week.

Come in from outside. There is a chair.

PiscesOne good crowded evening now costs you the following day.

Grain by grain, sand on a seabed got pressed into stone over a stretch of time nobody can picture. The green flecks were sealed in while it happened.

It never got dyed or heated. The blue and red versions sitting in the same shop almost certainly did.

Pisces, you were made of ordinary stuff under pressure, and the shine came later and by accident.

Everything anyone near you is feeling walks straight in through the front of you, and as a child you assumed that was standard issue for everybody.

Nobody told you it was not, so you never built a way to shut it. One good crowded evening now costs you the following day.
