Citrine is created when liquid magma from a volcanic eruption cools down and transforms into igneous rocks. During this cooling down period, silica acid bubbles shift from being a gas/liquid into a solid compound. The bubble becomes a hollow space in the igneous rock and the silica acid becomes Quartz crystals. Once the Quartz has formed, a large hollow is often called a “druze,” while a smaller hollow is a “geode.” These druze and geodes can be removed from the host rock and then split open to revel the crystals inside.
If no trace elements are present to change its color, the silica acid becomes Clear Quartz. If trace minerals are present, then the color changes. For example, Amethyst, Citrine, and Prasiolite all get their coloring from trace particles of iron heated to different temperatures. Citrine requires the highest temperature. As a result, it is often the product of heat-treating low-quality Amethyst. Ametrine is the rarest variety of Quartz, found only in Bolivia, it is a natural two-toned crystal that has both Amethyst and Citrine within it.
Citrine’s energy works well with its “friends” – crystal associates formed in the same geological environment. Try it in combination with Amethyst, Danburite, Muscovite, and Smoky Quartz.
