According to the laws of physics, a planet in the shape of a doughnut (toroid) could exist Physicists say that such a planet would have very short nights and days, and arid outer equator, twilight polar regions, moons in strange orbits and regions with different gravity and seasons.

Fata Morgna

A Superior Mirage that comes from the Italian term named after the Arthurian sorceress Morgan le Fay, from a belief that these mirages, often seen in the Strait of Messina, were fairy castles in the air or false land created by her witchcraft to lure sailors to their deaths. It’s also believed that this illusion caused the myth of The Flying Dutchman to emerge.

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.
