Moon flowers, yes? My grandmother loved these, we have them planted in our garden :)
looks like something out of Coraline :o
I have a story. We used to have a bunch of these outside our house. They really do open up like this as soon as it gets dark and they release this wonderful smell. My family used to go outside every day and watch them open. But what they don’t tell you is that bugs love them. When it gets hot out they’ll crawl inside them to keep cool. So one day little me, I was probably like 13, put my nose right down by it so I could smell it as it was opening… and a huge ass jumping spider launched itself at my face. Don’t trust the moon flowers. They’re full of horror.
That’s true in more ways than one. Moonflowers are actually datura - angel’s trumpets. They’re very toxic, and have been use for hundreds of years as a poison and hallucinogen.
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.
