Ametrine and Tourmaline have uneven coloring, they have smooth transitions from tone to tone.
⠀
Ametrine combines the beauty of Citrine and Amethyst. The colors shimmer from bright yellow to purple.

Single-color tourmaline is almost never found in nature. Its colors are very unusual: green-red, pink-white, blue-purple.
⠀
Even synthetic Tourmalines and Ametrines can look magical.

By choosing jewelry with such a stone, you will not have to choose between a variety of shades, because they combine several colors at once.
