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.
People thinkin I’ve got all these mad awesome gems and is hella rich.
I got one of these bad boys.
napping naked on top of a girl you like is one of the best things you can ever do. like not completely on her but your legs between hers, head on her boobs/ stomach while she’s scratching your head and back. thats the shit i look forward to when Im married
When I was a kid I thought your 20s were supposed to be fun, not filled with perpetual anxiety about financial stability and constantly feeling like an unaccomplished piece of shit.
That’s because it was fun for baby boomers and they basically gave us this impression it would always be like that, but then they ruined the economy.
I’m a writer. I’m supposed to have the right words to say. I should be able to string together elegant words and delicate sentences to express this delight. But I can’t. Speechless is all I can utter.
But to me, that’s more beautiful than any fairytale I’ve ever heard, any love story I’ve ever read, or any dream I’ve ever walked through.
So thank you, thank you for leaving me at a loss for all words."
