This is Alexandrite, it’s also called “emerald by day, ruby by night”
It changes colour based on whether the light source is from the sun or from a candle.
It does this because Alexandrite strongly absorbs yellow light due to chromium ions in its crystal structure, leaving the other colours behind. Light from the Sun emits all colours, but it peaks in the green, and our eyes are most sensitive to green, so in Sunlight Alexandrite is green.
Incandescent lights are things like candles and filament light bulbs. They also emit all colours of light, but they peak far, far into the red, so there’s not nearly as much green or blue, so under those, Alexandrite is red.
Gemstones are awesome.

I’ve always liked jellyfish, even tho they can be scary as hell sometimes.
This is amazingly beautiful.
I don’t know why I exist and I have begun to assume that I am a vessel to absorb the suffering of the world but hey that’s fine. I’ll be fine.

I’m alright? I’m drinking and dealing with the general self-loathing and sense of worthlessness I always deal with. I’m okay??? Mostly at least.and that’s a quote from Antigone that just gets me a lot…
"You’ve made your choice. Your death is the doing of your own conscious hand."
