Citrine is a type of quartz mineral that is known for its yellow to golden-brown color. It is composed of silicon dioxide, the same chemical compound as other types of quartz, but with small amounts of iron impurities that give it its distinctive hue. Citrine can be found in nature as well as produced synthetically by heating amethyst or smoky quartz. The transparency of citrine can vary, from transparent to translucent, and it has a vitreous (glassy) luster. It is a durable stone that is often used in jewelry, particularly for its warm and sunny color.

In metaphysical and spiritual practices, citrine is believed to have a variety of healing and energizing properties. It is often associated with the solar plexus chakra, which is thought to govern personal power, confidence, and self-worth. Citrine is said to promote clarity of thought, mental focus, and creativity, as well as attract abundance, prosperity and success. It is also believed to help release negative emotions, such as anger, fear, and depression, and to promote positivity, joy, and optimism. Citrine is sometimes called the "stone of manifestation" because it is thought to help people manifest their goals and dreams into reality. In addition, citrine is said to have a cleansing energy that can help purify and recharge other crystals and gemstones.
