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.

Ronald Erwin McNair was born in 1950 in Lake City, South Carolina. He was an American physicist and NASA astronaut and a man of many accomplishments. His favorite activities were running, boxing, football, playing cards, and cooking. When he was a 9-year-old boy he refused to leave the segregated Lake City Public Library without being allowed to check out his books. When the police knew about the incident, they let him keep those books and 26 years later, after his death, Lake City Public library was named after him. 

McNair had a bachelor degree of Science in Engineering Physics and a Ph.D. degree from MIT, in Physics. He gained national notoriety for his work in the field of laser physics. Above that, he was a 5th-degree black Karate instructor and jazz saxophonist.

Ronald McNair was killed on January 28, 1986, when the space shuttle Challenger exploded.

Don’t let people forget about such dedicated and notable Black men like Ronald Erwin McNair. His name deserves to be in all History books.
