Optical Calcite

Put it down on a line of writing and look through the top of it. The line doubles. Both copies are sharp.

That is light splitting in two on the way through. It is also a stone a coin will scratch, and one drop of lemon juice eats the polish off it for good.

Aries, you want one answer and you want it now.

Somebody in your life used to take too long, and the waiting felt like being ignored, so you learned to force a decision just to end the silence. Now you would rather have a fast wrong answer than an honest slow one.

Some things really are two things at once. Sitting in that is not weakness, and nobody ever showed you how.

Keep it away from the sink. Let the rest wait.

This is one of the least durable things in any collection. Hardness 3, so a coin scratches it, and a knock cleaves it into neat little rhombs.

Water is the real problem. Even slightly acidic tap water dulls the polish, and vinegar or lemon fizzes on the surface and takes the shine off permanently.

Taurus, you have been treating your own limits as a personal failure.

Somebody taught you that tiredness is laziness, probably by working themselves into the ground in front of you and calling it love. So you push through and pay for it on the Sunday.

A soft thing is not a weak thing. It is a thing with different care instructions, and nobody ever wrote yours down.

Dry cloth. No water. That is the whole of it.

People built instruments out of this. Clear blocks came out of Iceland and ended up in optical equipment, purely because of what the stone does to light.

Now it gets cut into cubes and sold as a clarity stone. Nobody at the till mentions that a splash of lemon takes the polish off forever.

Gemini, you can argue either side and you have stopped knowing which one is yours.

It started as survival in a house where having a position got you into trouble. Being able to see it their way kept the peace and kept you safe.

Now somebody asks what you actually think and there is a pause, and in that pause you pick whichever answer costs less. You have not heard your own opinion in a while.

What do you think, before you check the room?

It looks like quartz and it is nothing like quartz. This is calcite, hardness 3, where quartz sits at 7.

One drop of vinegar settles the question in a second. Calcite fizzes. Quartz, selenite and glass do nothing at all.

Cancer, you have been the soft one in a house that needed somebody hard.

So you learned to look sturdier than you are. You take the calls and you hold the plans together. Everybody assumes you can take it because you have never once said otherwise.

The cost is that nobody handles you carefully, and you have never handed anyone the instructions. They are not cruel. They genuinely do not know.

Tell one person what you are actually made of.

Water carrying dissolved calcium carbonate seeped through cracks in the rock. It filled an empty pocket so slowly that the whole space came out as one clear crystal.

Nothing hurried it and nothing was watching. Then somebody cut it into a cube, polished six faces and put a price on it.

Leo, you have never once been able to do anything quietly.

Attention was the thing that told you it counted, and you worked that out early, probably from one adult who only looked up when you performed. Now work that nobody sees feels to you like work that did not happen.

Most of what made you happened where nobody was looking. You have never given any of that credit.

The clear part grew in the dark.

Set it down on this line and look through it. Two lines, both sharp, sitting slightly apart from each other.

The doubling is real and testable, which is more than most claims about stones manage. The other honest test is a drop of vinegar, which fizzes, and takes the polish with it.

Virgo, you have been waiting for one right answer that was never on its way.

You were rewarded young for being correct, and it worked so well that being unsure now feels like being in trouble. So you research a decision until the decision expires.

Plenty of real questions have two true answers. That is not a failure of your research and it never was.

Pick the one you can live in.

It is soft enough that a fingernail is nearly a threat, and it splits into tidy rhombs if you drop it on tile.

It also cannot go near salt or acid. A fizzy drink spilled on it leaves a dull patch that never comes back.

Libra, you were taught that being easy to be around was your job.

One person at home had a mood that set the temperature, and you got good at adjusting before anybody noticed you were adjusting. It kept the house calm and it cost you a decade of knowing what you wanted.

Now you agree first and work out your position on the drive home. Everybody thinks you are fine with everything.

Disagree with something small on purpose.

This grew in the dark, in a gap in the rock, out of water with calcium carbonate dissolved in it. It filled the pocket so slowly that the whole space came out as a single crystal.

It has almost no defences at all. A coin scratches it, acid eats it, and any real knock cleaves it into rhombs.

Scorpio, you learned to look armoured because being seen once went badly.

Somebody read you accurately at an age when you had no way to defend yourself. They used it, and you have been building the outside ever since.

The people around you now are not that person. You have never let one of them close enough to prove it, and that is the part costing you.

Let one of them try.

It is not quartz and it is not glass. It is calcite, which is soft, and it dissolves in anything acidic.

The double image is the genuine thing about it. That part is not lore. It is light splitting in two on the way through, and you can test it on this page.

Sagittarius, somebody says there are two sides and you hear an excuse.

The adults around you were very good at complicated reasons for staying exactly where they were. You watched that, and you decided nuance was what people used to avoid doing anything.

So you made a rule that you would always just go. It has been mostly right, and it has cost you the two or three people who needed you to sit down and hear the second version.

Which one of them are you still not calling?

Somebody cut this into a cube and polished six faces onto it. The clear block on your shelf was a lump in a rock cavity not long ago.

Then it went out with a card promising clarity. What the card does not say is that tap water dulls it and lemon juice destroys the polish for good.

Capricorn, you have never been allowed to be the one who gets looked after.

You worked out young that you would be kept for what you could carry, and you have never tested whether that was true. So you became the person everyone else relaxes around.

Nobody asks you how it is going because you have trained them not to. You are very good at this and it is very lonely.

Let one thing be handled for you.

Look through it at a word and you get two words. Turn the stone slowly and the second one travels around the first.

That is birefringence, which only means the light splits and takes two paths. It is one of the very few things in a crystal shop you can prove while standing in it.

Aquarius, you can prove anything except that you are wanted.

You have arguments for everything, and you built them because being right was the one thing you could control in a house where the affection came and went. Nobody argues with you now, which is not the same as anybody being close to you.

Being correct has never once made you feel held. You keep trying it anyway.

Ask for something plainly this week.

This one cannot be washed. Water dulls the polish, salt harms it, and a drop of anything acidic fizzes and eats the surface permanently.

It cannot be cleansed the way people cleanse things either. A dry cloth is the whole ritual, and anybody telling you to run it under the tap has never held one.

Pisces, you run two versions of every conversation and you answer from the kinder one.

Other people's weather arrives inside you before you have identified it as theirs. Somebody told you to grow a thicker skin, which is advice from a person who has never once had to do this.

You are not going to grow one. You can get faster at noticing the exact moment it walked in.

Whose feeling got here first tonight?
