These fragments of chrysoberyl crystals have a good color change effect (pleochroism) under different lighting conditions. Chromium atoms (in different% ratios) in the composition of chrysoberyl - make it possible to identify it as a color-changing alexandrite.

All these alexandrites have no jewelry value.

Bright dark blue - green, bluish - green, dark grass - green, olive - green color of chrysoberyls in daylight.
In the evening, artificial lighting or in complete darkness (an ordinary candle, as an example)- we observe the same samples already in light lilac, lilac or purple shades.

All samples have a bright red glow under short-wave UV irradiation - this is how alexandrites are sorted from simple chrysoberyls that do not glow in UV.

Bright red glow in UV can be observed in photo 8##3.
