Can Black Obsidian Go in Water? My Honest, Tested Answer (2022)

Last Updated on December 29, 2023

If you’re like me and always looking for the ideal way to care for and reenergize your crystals, gems, stones, and minerals, then one of the first questions you may have found yourself asking about that gorgeous piece of black obsidian—the almost pure black stone with the smooth and reflective appearance—in your collection was this: Can you put black obsidian in water?

I’m happy to tell you that, yes, you can put black obsidian in water.

The reason I’m so happy to tell you this is because—personally—black obsidian is by far my favorite stone in my collection and I try to care for it as best as I can, which means putting it in water on a regular basis. Actually, I’m considering purchasing a few more black obsidian stones so I can spread them out around my home and office space to benefit from their energetic properties.

Maybe you, too, would like to learn about how to cleanse your black obsidian and why you should do so on a regular basis. If this is the case, you’re in the right place!


How should Black Obsidian be Cleansed in Water?

Another reason I really enjoy black obsidian is because—compared to other stones, crystals, gems, and minerals—it is so easy to clean and care for!

When it comes to the Mohs Hardness Scale—a tool used to determine the hardness or softness of minerals that you may wish to acquaint yourself with if you are a regular collector—black obsidian sits between a 5 and 6. Because black obsidian is higher than a 5, it is generally safe to place or cleanse the stone in water, though it is always a good idea to research each individual mineral prior to cleansing.

However, there are a couple factors to consider when cleansing black obsidian: The temperature of the water and the length of time it spends in the water.

What Water Temperature can Black Obsidian go in?

Water temperature is a very important factor when cleansing any stone, mineral, gem, or crystal, and it is no different for black obsidian.

When cleansing black obsidian, it is best to be mindful of the water temperature: Boiling hot water and ice-cold water could both potentially damage, break, or crack the stone.

This is especially important if you wish to utilize its energetic properties in the bathtub. If you do decide to place black obsidian in the bathtub, ensure that the water is not hot enough as to cause cracking.

How Long can Black Obsidian go in Water?

Black obsidian is a fairly tough stone—it is formed by volcanic eruptions and activity, so we wouldn’t expect anything less—and it can go in water for extended periods of time, even overnight if it requires a deep cleaning. If you use your black obsidian as a source of positive energy and you haven’t washed it in some time—say a month or so—then soaking it in a bath of lukewarm water overnight will help get rid of any negative energy it has absorbed.

It’s also just as easy to give black obsidian a quick rinse—perhaps every day—to rid the stone of negative energy on a more frequent basis. If you do this, then it’s not necessary to deep clean your black obsidian.

Why should Black Obsidian go in Water?

Like many stones, crystals, gems, and minerals, black obsidian has energetic properties including wonderful protective and purifying energies, as well as intense healing energies.

This is why black obsidian is a particularly good stone for placing directly in the bathtub when you are taking a bath, or even dropping into your drinking water every now and then to help heal the body and mind.

If you really wish to get the full effects of black obsidian, then you might even try submerging it in moon water—water that has been left out to soak up the energy of the moon—perhaps once a month. If you deep clean your black obsidian once a month, anyway, you could try syncing up its cleansing schedule with the moon cycle. A full moon is ideal for creating moon water since it produces the most energy.

Of course, if you do not have the time to create moon water, then tap or filtered water are always safe options for cleansing your black obsidian!
