Is Selenite Waterproof? Exploring the Properties of This Unique Crystal

Selenite, a stunning and versatile crystal known for its ethereal beauty and translucent quality, is often used in various applications, including spiritual practices, home décor, and even water purification. However, a common question that arises is is selenite waterproof?

The answer, unfortunately, is no, selenite is not waterproof. This may come as a surprise to some, given its frequent use in water-related practices. To understand why, we need to delve into the unique properties of selenite and how it interacts with water.

Understanding Selenite's Composition and Structure

Selenite, a variety of gypsum, is a soft and delicate mineral composed of calcium sulfate dihydrate (CaSO4·2H2O). This chemical composition reveals its susceptibility to water. The "dihydrate" part signifies that two water molecules are chemically bound within the crystal structure. This inherent water content makes selenite vulnerable to dissolution and deterioration when exposed to excessive moisture.

How Water Affects Selenite

Water can significantly impact selenite in several ways:

  • Dissolution: When selenite is submerged in water, its chemical bonds weaken, leading to gradual dissolution. The water molecules interact with the crystal structure, pulling away calcium sulfate molecules and leaving behind a weakened and potentially damaged selenite piece.
  • Erosion: Even if not fully submerged, prolonged exposure to moisture, such as humidity or splashes, can cause erosion of the crystal's surface. The delicate layers of selenite can become rough and dull, affecting its aesthetic appeal and potentially compromising its structural integrity.
  • Cloudiness and Discoloration: Water can cause clouding and discoloration in selenite. As water seeps into the crystal, it can create tiny air bubbles or react with impurities present within the selenite, resulting in a milky or cloudy appearance. This can also cause the crystal to appear less translucent and vibrant.
  • Mold and Mildew: Selenite, like any porous material, can be susceptible to mold and mildew growth if exposed to prolonged dampness. Mold spores can germinate and thrive in damp environments, leaving unsightly spots and potentially releasing harmful toxins.

Selenite and Water-Related Practices

While selenite is not waterproof, it is still used in various water-related practices. For instance, some people believe that selenite can purify water. This is based on the idea that selenite's high vibration can harmonize the water's energy. However, it's important to note that this is not scientifically proven, and using selenite for water purification should be done with caution.

It's crucial to understand that selenite's ability to purify water is not based on its physical properties but rather on its energetic properties. The belief is that selenite's high vibration can cleanse and energize the water, potentially improving its taste and quality. However, there is no scientific evidence to support these claims.

Safe Handling of Selenite and Water

Here are some tips for safely handling selenite and water:

  • Avoid submerging selenite in water: It's best to avoid submerging selenite in water altogether to prevent dissolution and erosion.
  • Keep selenite away from direct water sources: Avoid placing selenite near sinks, showers, or other sources of splashing water.
  • Clean selenite gently with a soft, dry cloth: If your selenite becomes dusty, gently wipe it with a soft, dry cloth. Avoid using water or any cleaning solutions.
  • Store selenite in a dry place: Store your selenite pieces in a dry, dust-free environment to protect them from moisture damage.


While selenite is a beautiful and versatile crystal, it is essential to remember that selenite is not waterproof. Water can have detrimental effects on the crystal, leading to dissolution, erosion, and discoloration. Therefore, it's crucial to handle selenite with care and avoid exposing it to excessive moisture. By following these guidelines, you can ensure that your selenite pieces remain beautiful and vibrant for years to come.

Remember, if you're unsure about how to handle selenite, always consult with a reputable crystal expert or dealer for guidance. Enjoy the beauty and energy of selenite, but handle it with care and respect for its delicate nature.
