This is an image of Tourmaline, photographed from two different angles with polarised light.
Tourmaline is Pleochromic, meaning it changes colour as the angle changes. This isn’t a surface effect like the changing rainbow colours on an oil slick, it happens throughout the crystal.
The crystal structure in Tourmaline is anisotropic, which means it looks different from different directions. That means light coming in from different directions experience different effects and can get absorbed in different amounts, leading to something very cool.
It also happens with other crystals, like this Cordierite
There needs to be a video of this!
Here’s a gif. I like gifs. This is Iolite, the gem version of Cordierite, changing colour as the angle changes. Pretty. If you absolutely need a video though, here’s the source
it’s a god damn samsquatch ricky
Sphaerodactylus nicholsi, one of the smallest geckos in the planet. (x)
This is amazing. Look how small it is. It has a heart and a stomach and a brain. And it’s this small
That cute little guy could run right up your nose and you wouldn’t even know.
I don’t get paid for it and I’ve never studied under an artisan, so I’m more like an enthusiastbater
