Amethysts with a complete change in color (such as Alexandrite) do not exist! I have rare African amethysts with a color shift (with a change in color shades: blue-violet in daylight or red-violet in incandescent lamps)

Amethyst appears two-colored in the photo, one part is bluish-purple and the other is reddish-purple.
This is an optical effect.
I lit two lamps on opposite sides of the stone, so it was such an effect.
So you can do with all the stones that change color.
