People with a strong fire element are suitable to wear crystal, because according to the theory of the five elements' mutual generation and overcoming, water overcomes fire, so fire-related ornaments are not suitable for people with a fire element. Wood generates fire, so wood-related crystals are beneficial to people with a fire element. Generally, green and blue crystals belong to wood. Green quartz, green olivine, green moonstone, etc., are suitable for people with a fire element. Wearing wood-related crystals can enhance career luck, attract wealth, accumulate wealth, bring in money, and increase confidence.
Fire-related crystals are also one of the preferred crystals for people with a fire element. Most red crystals belong to fire. Fire-related crystals include red quartz, red pattern, pink crystal, and pink tourmaline. People with a fire element wearing fire-related crystals will enhance belief, confidence, wealth, joy, good fortune, and prosperity.

The fire element is divided into two types: Yinyang and the day stem. The term "fire element" usually refers to the five elements of the day stem. Among them, Bing is Yang fire, and Ding is Yin fire. A person with a fire element refers to someone whose natal chart's Yinyin is fire. According to the theory of the five elements' mutual generation and overcoming, people with a fire element are suitable to wear gold, because fire overcomes metal, and metal can bring good fortune and remove excessive fire energy.
For people with an adequate fire element, wearing gold can enhance their feng shui and fortune. However, whether a person with a fire element is suitable to wear gold depends on their specific condition. If a person with a weak fire element wears gold to reduce fire energy, they may become even weaker in fire. When fire is weak, water becomes strong, which can make people with a fire element or weak fire element have poor health, be prone to illness, and lack energy in doing things.
