Trapiches are minerals that form with a radiating star of inclusions between growth sectors. Some form with a core or hub with spokes radiating outward from the core, while others form spokes from the center of the gem.
 
Ametrine is a combination of amethyst and citrine, which are both a variety of quartz. Amethyst is clear quartz with the presence of manganese, making it purple. Citrine is clear quartz with the presence of iron, making it golden yellow.
 
As a stone of both balance and connection, ametrine is believed to relieve tension, bring serenity and stimulate creativity, as well as balance mental stability and self-confidence. Ametrine is considered a double boost to remove toxins from the body, as both amethyst and citrine are detoxifiers.
