What are crystals, and how do they work?
A crystal is a solid material whose atoms, molecules, or ions are arranged in a highly ordered, repeating pattern that extends in all three spatial dimensions. This perfect geometric arrangement is what gives crystals their beautiful, structured faces. As we covered in our previous post, How are Crystals Formed? Everything You Need to Know, these incredible formations occur in several ways. The most common methods are through the slow cooling of magma, the evaporation of mineral-rich water, or the deposition of minerals in rock fissures over millions of years.
Whether you’re a seasoned collector or just beginning your journey into the world of crystal energy, understanding a crystal’s core properties is key. From its physical hardness to its purported spiritual uses, each stone tells a unique story. The table below provides a concise overview of some of the most popular crystals, detailing their key characteristics and the powerful meanings associated with them.

Practical and spiritual uses of crystals
While geologists study crystals for their physical properties, a parallel world of thought suggests these minerals possess unique energies that can influence our lives. From aiding meditation to bringing a sense of calm to a room, the belief in crystal energy is a powerful and personal one. The information below offers a fascinating glimpse into how some of the most popular crystals are perceived from both scientific and spiritual perspectives.
Pyrite
Practical/Real World Uses
Chemistry: A common iron sulphide mineral. It is a significant source of iron ore and is used in the production of sulphuric acid.
Believed Spiritual Influence
Good Luck & Abundance: Often called “Fool’s Gold,” Pyrite is believed to be a powerful stone for attracting luck, wealth, and abundance. It is used to stimulate creativity and determination.
Amethyst
Practical/Real World Uses
Geology: A variety of quartz, its purple colour comes from trace amounts of iron and natural irradiation within its crystal structure. It is a stunning, sought-after gemstone for jewellery.
Believed Spiritual Influence
Calm & Intuition: Widely used to promote a sense of calm and a restful sleep. It is also believed to enhance intuition, open the mind, and reduce stress and anxiety.
Clear Quartz
Practical/Real World Uses
Electronics & Optics: Due to its piezoelectric properties, it’s used in watches, radios, and other electronic devices to maintain a precise frequency. It is also a key component in lenses and prisms.
Believed Spiritual Influence
The Master Healer: Believed to amplify energy and thought, as well as the effects of other crystals. It is considered a powerful tool for clarity, focus, and spiritual development.
Rose Quartz
Practical/Real World Uses
Industrial: A type of quartz used in construction aggregates and roadbeds when it is not of gem quality.
Believed Spiritual Influence
The Stone of Love: Believed to be a powerful heart chakra stone that promotes unconditional love, compassion, and emotional healing. It is used to attract love and strengthen relationships.
How to cleanse & charge crystals
Just as we might cleanse ourselves of negative energy, many crystal enthusiasts believe that crystals need regular cleansing to release any built-up or unwanted energies. It is believed that once cleansed, they can be recharged to amplify their natural properties. Should you wish to engage with crystals in this way in an effort to dispel any negative or harmful aura, we’ve compiled the most popular crystal cleansing and charging methods.
How to cleanse crystals
- Moonlight Bath: Place your crystals on a windowsill overnight, especially during a full moon, to let the light purify their energy.
- Smudging: Pass your crystal through the smoke of cleansing herbs like sage or palo santo.
- Sound: Use a singing bowl or a tuning fork to create a sound that cleanses the crystal’s energy field.
How to charge crystals
- Sunlight: Some crystals, like Clear Quartz and Carnelian, can be placed in direct sunlight for a few hours. (Note: Be cautious, as some crystals like Amethyst or Rose Quartz may fade in direct sunlight).
- Earth: Burying your crystal in the earth for a day can help it reconnect with the planet’s energy.
- Other Crystals: Placing your crystal on a Selenite slab or geode is a popular and safe method to recharge its energy.
Can crystals help well-being?
How you choose to use your crystals is a personal journey. Whether for collecting purposes, meditation, to improve your mood, or to create a calming atmosphere, the intention is what matters. Some even use crystals to attempt to assist with issues such as anxiety. Practices used by those looking to relieve stress and worry using crystals include:
- Meditation: Holding a calming crystal like Amethyst or Lepidolite in your hand during meditation to help focus your mind and ground your energy.
- Placement: Placing a crystal on your desk at work or on your bedside table to create a peaceful environment.
- Carrying: Carrying a small tumbled stone in your pocket or bag to keep its energy with you throughout the day.
We must stress that there is no scientific link that using crystals offers healing properties, like decreasing anxiety or stressful thinking, that some believe they have. What crystals do is offer a way for people to channel their emotions and thoughts in a way they deem productive. Much like a stress ball, which is not a medical prescription but can provide short-term support and relief, for some people, these crystals can briefly facilitate a sense of calmness and tranquillity.
Crystal combinations
Those who enjoy the fantastical side of crystals often experiment with combinations to see what energies work well together. While most crystals can be used together, a commonly asked question is, ‘Which crystals should not be together?’ Generally, it is believed that a high-energy stone may clash with a very calming one. For example, some people prefer not to combine highly energising crystals like Carnelian with deeply relaxing ones like Lepidolite. Trust your own intuition; if a combination doesn’t feel right, it likely isn’t.
