Ametrine crystals are made of alternating sectors of purple and yellow to orange color. Slabs cut perpendicular to the c axis of the crystal look a bit like a pinwheel. The purple sectors are situated under the positive rhombohedral faces (r), and the yellow sectors under the negative rhombohedral faces (z).
While the purple sectors are made of amethyst, the yellow or orange sectors are not made of citrine, because they are colored by inclusions of iron compounds and would more properly called ferruginous quartz. Accordingly, upon heating ametrine the purple sectors pale, while the yellow-orange sectors keep their color.
Ametrine has been synthesized hydrothermally in Russian laboratories (Balitsky et al., 1999).

A green to blue-green variety of K-feldspar, usually microcline, but sometimes applied to orthoclase.
The color is usually caused by an elevated content of Pb (up to 1.2% PbO, [2]).
However, there are also indications that the green color of some microcline is caused by divalent Fe[1]. Overenthusiastic uses of this name include giving this name to slightly gray-green hues in microcline that are often photosensitive and turn from greenish gray to light smoky gray. Sunlight can sometimes enrich the color of genuine amazonite.
