From Trash to Treasures

If any of my family reads this, I might be in deep shit, but at the moment, I do not care!
I was looking through some junk at my Grams, and I found a purple gemstone, it was a little dusty and dull, I figured its synthetic.
I found a ring, missing a stone, and the setting prongs are a bit bent/broken, but I found that the gem fit into the setting, so I cleaned them both, and affixed the gen to the setting - it looks pretty good (will insert pictures later when I take some)   I got quite a surprise when I got up this morning, see, I went to bed wearing a ring with a purple gemstone, but when I woke up this morning, the stone was a pretty blue-ish green !!!
I was perplexed, as it turns out, the gem I now own, is Alexandrite; a gemstone known for its color changing properties-according to Wikipedia:  Alexandrite, a strongly pleochroic (trichroic) gem, will exhibit emerald green, red and orange-yellow colors depending on viewing direction in partially polarised light. However, its most distinctive property is that it also changes color in artificial (tungsten/halogen) light compared to daylight. The color change from red to green is due to strong absorption of light in a narrow yellow portion of the spectrum, while allowing large bands of blue-greener and red wavelengths to be transmitted. Which of these prevails to give the perceived hue depends on the spectral balance of the illumination. Typically, alexandrite has an emerald-green color in daylight (relatively blue illumination of high color temperature) but exhibits a raspberry-red color in incandescent light(relatively yellow illumination).


Mine is a Brazillian Alexandrite, known for their purple hue in incandescent light - so it looks like a light amethyst in 'fake light' and like a blue/green in sunlight.


Neat.
and apparently quite valuable :)
