“Goldstone is a man made gemstone that has been around since the European Renaissance.
Early monks working at a glass factory near Venice, Italy were practicing alchemy when molten copper accidentally tipped into a molten glass container.
This crystallized into thousands of tiny crystals and formed a melt with golden light sparkles. This is how the first goldstone came about. Though it is not technically a gemstone, it is often referred to as one.”
Like space in the palm of my hand.
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.
