Electra Brilliant is here!

i love crystal and charles having an emotionally inadvisable hookup charles can't even FEEL in one room while niko and edwin sit cross-legged on niko's bed watching scooby doo in the other

In the comics, Crystal has her near death experience at this art show of her parents’. In the show, this is where they are when she calls them

Researching for "These Brilliant Lights", my Cryland Edwardian!AU. That's fun. I have next to no knowledge of the social norms, etiquette etc of that time, but I'd like to be familiar with it if I'm going to be throwing Charles, Edwin, Niko and Crystal into all of this

Pleochroism in gem quality zoisite var. tanzanite

Apparently we're doing this...

*my pictures, not my crystal

Ever wondered why the colour of some gemstones seems to shift as you view them from different angles? Perhaps are you were looking at a pleochroic gemstone!

Pleochroism is a body colour effect seen in transparent to translucent, optically anisotropic* crystalline material caused by differential absorption of the polarised light rays following different paths through the gemstone, and causing a change to perceived body colour when the stone is viewed from different directions.

...Okay, but what does that mean?

Pleochroism means 'many coloured'. When light passes through a crystal, it is sometimes split into two rays - each ray takes a slightly different path, and because it encounters different atoms within the crystal structure, it is modified to a different colour.

When both different coloured rays of light exit the crystal, your eye resolves them as a single colour. Clever, right? :D

The four photos above are of the same crystal. The top photos show the crystal from two different angles - one looks distinctly more purplish than the other, right? That is eye-visible pleochroism!

Even gems that show pleochroism don't always show it strongly enough to see with the naked eye. But this tanzanite crystal does.

The bottom photos show the same crystals viewed through a type of polarising filter called a dichroscope. The dichroscope is made of polarising film where each half lets through only one of the rays of coloured light - meaning you can see each of the two colours at the same time, one in each half of the filter!

But wait!- I hear you cry. Why are there THREE different colours??

Hmm well this is getting into a deeper discussion of crystal habits and their optical behaviours, so for now let's say that depending on the symmetry of the crystal, an optically anisotropic* stone can show two or three colours - but only ever two in one direction! You have to turn the crystal to see the third colour.

If a stone shows two colours we say it is dichroic, if it shows three it is trichroic. This is the maximum number of colours you will see.

When you view the tanzanite crystal in the position in the left photo, the light rays being transmitted are blue and reddish-purple. Your eyes resolve this to show a purpley-blue colour. Neat!

But in the position from the right photo, it's transmitting blue and yellow. Wild! The yellow ray dilutes some of the intensity of the blue, so the colour you see is a weaker blue tone.

The photo I'm missing from my set is the crystal viewed from top-down, which would then show a purple and yellow split through the dichroscope!

So turning the stone, or moving your head position relative to the position of the stone, really does change its colour, because you are perceiving a different set of coloured light rays being transmitted through the stone!

When fashioning a rough crystal, a lapidary (that's a stone cutter) would to orient the crystal so the best colour is face-up - ie. when you look at the finished polished stone, you will see the most attractive balance of colour. What is considered ideal varies with the stone - you might cut a very dark crystal to show its lighter colour, or a pale one to show the most intense colour it is able to!

Fun additional fact - tanzanite can be heated to improve its colour. It does this by removing the yellow element entirely, meaning you will see intense bluey-purple tones from all angles! The wonders of stone treatments!

*Edit I am misleading you by saying you will see bluey-purple in all directions... in two directions (as tanzanite is a biaxial gemstone) you will find an optic axis, which is a direction of optical isotropy in an otherwise optically anisotropic* gemstone. So in this direction, you will only have a single transmitted ray of light, not two!

*I use the phrase optically anisotropic a couple of times and it's hard to explain without a whole separate citizen lecture on crystallography, but the quick summary is that it means a crystal in which light behaves differently as it travels in different directions - such as the differential absorption resulting in different colours in pleochroism! This is as opposed to an optically isotropic crystal, where light behaves the same way in all directions of travel.

And that is a recited-from-memory summary of pleochroism! :D (please don't tell me off if I got any of it wrong I didn't go upstairs to check my notes ;_;) (I mean I didn't get any of it wrong but my quoted definition probably wasn't word perfect ^^;)

@royallykt thank you so much for your interest i hope you enjoyed learning about all this :)

Happy World Manta Day! Mantyke is the only Pokémon so far that requires the presence of another Pokémon (Remoraid) to evolve! What do you think of the Mantine evolution line? https://pokehexdex.wordpress.com/0226/01/01/mantine/

No word from Sycamore yet, but this new entry into my life demands some kind of name. It wouldn't be right to keep calling it "the mysterious Pokemon," would it?

I think after observing some of their behaviors, the way the light reflects off their shell like no mineral I've ever seen, how if they're not dozing under my heat lamp, they're watching me browse on my phone with such interest...

This new species, if that's what it is: I christen them Coquillant. They have shown no interest in Poke Balls yet, but I will inevitably have to figure out some way to transport them.

Especially because I do believe Coquillant will prove quite useful in my upcoming mining trip.

Little Miss Electra, the tiny tornado taking over the Brilliant household! One minute she's flinging food everywhere, the next she's giving that "who, me?" innocent look. But she’s never too busy causing chaos to break out her best dance moves. This little diva knows how to keep the whole family on their toes… and boogie-ing along! 💃💥

Good news! The second Cryland fic I've been planning is pretty much done. Job jobbed! Title is "These Brilliant Lights" from the song "You're Enough" by Sleeping at Last. It's going to be an Edwardian AU, and I'm so excited about it.

Day three of soft resetting for a shiny Raikou in Ultra Sun. When I get it, I’ll have seven Legendaries from gens 1-6 left to get (Latios, Reshiram, Ho-oh, Tornadus, Groudon, Landorus, and Kyurem)

I was hunting for the two Nido lines at the same time in Let’s Go Eevee but after one shiny female after a chain of 300+ then passing over a shiny dragonite and chansey while chaining another 500+ (total chain of 850 some), I broke it for a spare shiny Ratatta because if it was taking that long I might as well restart the chain. I’m gonna take a break from the nidos to hunt Krabby, they’re being the most difficult for me so far.

I’m working on both my livedexes tho I’m only missing a few legends and event mythicals for the regular one, but for my shiny livedex I’m going to offer up my spare shinies for shiny trades if anyone would be interested in the future.

Other just refers to Pokémon Mystery Dungeon or Pokémon Ranger or something like that.
