This is particularly important for people with electromagnetic hypersensitivity syndrome (EHS), but may well be just as important for all of us. Symptoms of chronic EMF exposure include insomnia, inability to focus, joint inflammation, and headaches.

Controlling EMF in your home environment can be accomplished through several strategies. On the direct effect end of strategies, you can employ shielding materials such as metal sheeting, metal meshes, and metal-containing anti-EMF paint. However, these approaches require area sampling for field strength and construction work or painting. They can also become expensive solutions, although they are guaranteed to be effective.

On the indirect effect end of strategies, many people advocate using crystals to direct energy flow in their home or work environment. But, not just any crystal will do and minerals have differing abilities and will address different situational issues.

In general, when choosing crystals for your home it is best to avoid silicate-based crystals like lepidolite, opal, and quartz. Lepidolite is often marketed to help with stress, depression, and use advocates also claim it works for EMF.

Silicate-based crystals are not good choices for EMF protection and can actually amplify EMF signals. Quartz crystals were used in early radio sets for this very reason.

Our Best Anti-EMF Crystal Reviews and Comparisons

1. Magnetite

Product Highlights

Magnetite is an iron-based mineral (Fe3O4) that is ferrimagnetic. Sources of magnetite may either be weakly magnetic or strongly magnetic (the latter known as lodestone), so although you may want to block EMF from your microelectronics, keep this stone away.

Magnetic fields from magnetite will ruin information storage media like tapes, hard drives, and SSDs. This stone, as with all stones we will review here, is meant to apply an area effect.

Magnetite is a ferromagnetic material, meaning that the crystalline structure is arranged in an array of alternating rows of atoms with identical magnetic moments for most of its structure. This produces a polarity in the crystal, just like a magnet, in which case a magnetite sample would also be ferromagnetic.

Magnetite harmonizes area EMF and also has positive effects on health and mental perspective. It brings intellect and emotions into balance and consequently magnetite is found in substantial amounts in the brain, particularly in areas related to motor function and areas associated with cognition (hippocampus and cerebral cortex).

The product linked here by Bella-Gems is a beautifully polished sphere of magnetite approximately 1-inch in diameter. An assortment of these magnetic spheres can be used to make a pyramid formation as an interesting addition to your living space.

Features

  • Blocks EMF
  • Balances emotions and thoughts

What We Like About Magnetite

The smooth polished appearance of the magnetite sphere is aesthetically pleasing and is a perfect sphere. By stacking these spheres, which are magnetic and stick together strongly, you can form a pyramid (with 30 for a 4-inch) or cube structure as a healing center and room decoration, or drill them out to use in jewelry.

What We Don’t Like About Magnetite

This is not really a bad feature, just one for which users must be aware: keep these spheres away from your computer, or the storage drive is toast.

PROS

  • EMF blocker
  • Beautifully polished sphere
  • Magnetic

CONS

  • Also… magnetic (so keep away from your laptop)

2. Hematite

Product Highlights

Hematite is another oxide of iron (Fe2O3) arranged in a rhombohedral lattice array. It is actually much harder than iron itself, but more brittle and produces similar effects as magnetite for health in addition to blocking EMF.

Hematite does not have strong magnetic properties and is actually a canted antiferromagnetic mineral at room temperatures. Antiferromagnetic materials have atoms arranged with magnetic moments “front-to-back” in alternating rows, so there is no overall strong magnetic field directed to the stone.

It is referred to as a “canted” antiferromagnetic because the material has a non-zero magnetic moment above its Morin transition point (which is about -23°C; below that it is strictly antiferromagnetic), meaning it is weakly ferromagnetic at room temperatures and up to its Neel temperature (which is 675°C, so don’t worry about it).

The hematite product we feature here is by Healing Crystals India and is a polished but course-looking 40 mm to 50 mm sphere (roughly 2 inches in diameter). Since these are not magnetic spheres, stacking them in a pyramid formation as room décor requires that you place them in either a basket or a tray with tall sides (but it can be done).

Features

  • Blocks EMF
  • Aesthetically-pleasing sphere
  • Has a texture
  • Weakly magnetic

What We Like About Hematite

The shape and appearance of this hematite sphere are very pleasing to the eye. It is smoothly polished, but unlike other smaller hematite stones (which look like opaque black glass), this sphere retains the grain and texture of the original stone.

This texture gives the sphere some presence as a decoration instead of having a highly-polished surface which does not provide a good depth of field for the eye.

What We Don’t Like About Hematite

No real negative with this stone, although it looks like grapeshot, a small antipersonnel cannonball.

PROS

  • Interesting conversation piece
  • Appealing texture

CONS

  • None

3. Shungite

Product Highlights

Shungite is a lustrous black mineraloid (non-crystalline) that is mostly carbon (50-98%, depending on the grade). Shungite also contains fullerenes in trace amounts.

Apart from EMF-shielding abilities, Shungite has antimicrobial properties and can purify water, can reduce oxidative stress when combined with water or applied to the skin, reduces inflammation, and has beneficial health effects toward treating organ problems, asthma, joint problems, and allergies. It also reduces stress, which requires no direct contact.

Shungite was first discovered in Karelia, Russia near the village of Shunga, however the term “shungite” has only been used since 1879 after its first formal geological description. The primary Shungite deposit is at the Zazhoginskoye field along Lake Onega.

Smaller deposits are found in various locations around the world, yet the Karelia source strata are considered the best Shungite mineral in the world. Despite the first formal use of the term “shungite” as late as 1879, properties of the rock strata near Shunga were known since the days of Peter the Great (Peter I) when the great-grandmother of the tzar was sent into exile.

She was a sickly woman and ended up in the village of Karelia. After regular bathing in a shungite spring, she regained her health.

When the tzar became aware of this, he ordered a spa to be built in the spring of 1713. The source of the spring’s power after some study was determined to be the shungite stone deposits, so Peter issued a decree stating that every Russian soldier is issued and required to carry a shungite stone to be used for enhanced wound healing and water purification.

Features

  • Beautiful decorative pyramid (4-inches across at the base)
  • Type III shungite (50% carbon)
  • Contains small pyrite intrusions
  • Redirects EMF

What We Like About Shungite

The stone pyramid with its black luster looks really cool. The natural grain of the rock formation is infused with veins of pyrite that makes a nice contrast and adds to its anti-EMF function.

What We Don’t Like About Shungite

Although it looks great, the pyramid is only a type III shungite. Higher shungite grades with more carbon content are considered better for EMF, but the pyrite helps.

PROS

  • Looks great
  • Nice decoration
  • Interesting texture to the stone

CONS

  • Only a type II shungite

4. Fluorite

Product Highlights

Fluorite is a halide series mineral made of calcium fluoride (CaF2) and tends to form in isometric and octagonal crystals. Actual fluorite is transparent and colored forms are those with an admixture of metals such as copper, silver, tin, zinc, or lead.

Fluorite is thought to stabilize and cleanse auras, as well as heal the body from electromagnetic stress. In addition, fluorite is thought to absorb and cleanse negative energies in the immediate environment.

The product featured here is an aqua fluorite hexagonal crystal column that can vary in size from 2.4-4 inches in length.

Features

  • Aqua green and translucent
  • Beautiful
  • Each crystal is completely unique
  • Fluorescent

What We Like About Fluorite

This is a very nice-looking crystal and very appealing to the eye with differing shades of green-blue, turquoise, and aqua coloring. The grain of the crystal is cut on the diagonal and gives the appearance of a swirling effect, which is thought to direct energies.

Whether turned into a pendant or set with other crystals as room décor, the fluorite crystal looks great and can be captivating to stare into.

What We Don’t Like About Fluorite

Some customers have complained of receiving greyish or opaque crystals. When these are cut, it is luck-of-the-draw as to which crystal a customer will receive.

PROS

  • Real crystal, not reconstituted
  • Beautiful lattices
  • EMF absorber
  • Large and weighty

CONS

  • Colors of crystals vary (they are natural, after all)

5. Black Tourmaline

Product Highlights

Although we said above to avoid using any silicate-based crystals for EMF protection, black tourmaline, in particular, is one exception. This form of tourmaline contains iron deposits which give it its black color.

Other metals can give tourmaline a variety of different colors, but black tourmaline with its iron content is of Shorl or Dravite deposit origins. Dravite is found in regions of Austria and Shorl is more common and deposits are found in Germany and other places around the world.

Black tourmaline, apart from its EMF absorbing properties, is also thought to contribute to boosting immune health and has emotional effects towards promoting good compassionate behaviors.

The product featured here is a Schorl black tourmaline natural crystal and has a rough-textured hexagonal form about three inches in length.

Features

  • Black and rough in texture
  • Authentic Schorl black tourmaline

What We Like About Black Tourmaline

This Schorl black tourmaline is from mines in Brazil and has high iron content to negate any silicate-based EMF amplification effects.

What We Don’t Like About Black Tourmaline

Black tourmaline must be handled with care since the crystals are brittle, although they are rather hard as well (about a 7 on the Moh’s scale).

PROS

  • Black and rough
  • Interesting to look at
  • Iron content is great for EMF

CONS

  • Brittle crystal, so don’t drop it

6. Aventurine

Product Highlights

Aventurine is also quartz, silicate-based crystal with a jade-like green appearance, but commonly has specs of hematite and goethite (both iron forms). The mineral is thought to stimulate creativity and emotional stability in addition to its EMF properties.

The product featured here is a beautifully polished egg of green tourmaline from India by YWG Stone Store that comes with a wooden cup stand and a velvet pouch for storage. It is approximately 1.6 inches high and weighs about 1.8 ounces.

YWG Stone Store also sells other crystal stones in egg shapes, so you can get a whole decorative collection if you wish.

Features

  • Green aventurine
  • Egg shape (size of a small hen’s egg)
  • Wooden stand

What We Like About Aventurine

This small polished green aventurine egg is just darling and would look absolutely fabulous in your salon along with a few other egg crystal friends. The wooden stand is a nice and thoughtful addition.

What We Don’t Like About Aventurine

Since these are natural stones, some customers have received theirs with cracks and some eggs separated (no pun intended).

PROS

  • Polished
  • Egg shape looks decorative
  • Wooden stand

CONS

  • Some received with cracks or broken

7. Pyrite

Product Highlights

Pyrite, otherwise known colloquially as “Fool’s Gold”, is an iron sulfide (FeS2) with a metallic luster and a color around the hue of pale brass, which is why some people mistook it for gold. In Roman times, pyrite was used in fire starter kits with steel.

It is comprised of iron but is non-magnetic so you can use it near microelectronics with no worries. The crystalline structure of pyrite is a simple cubic lattice and the mineral tends to also form cubic natural crystals.

The product featured here by Beverly Oaks is rather unique in that it superficially resembles a tree. A one to two-inch tall cluster of pyrite crystals is set upon a metal stand (the “trunk”) and makes for a great conversation piece.

Pyrite, like its other iron-based cousins, absorbs local EMF and is thought to enhance memory and brings a sense of well-being.

Features

  • A cluster of shiny pyrite crystals
  • Metal stand
  • Non-magnetic

What We Like About Pyrite

We like this little decorative arrangement which looks like a miniature tree, with its pyrite canopy and metal trunk.

What We Don’t Like About Pyrite

No negatives with this product, although one user received the wrong product from Beverly Oaks.

PROS

  • Miniature metal tree!
  • Nice living room or office decoration

CONS

  • None

FINAL VERDICT

For pure appearance, we are inclined to choose the shungite pyramid. It’s big, beautiful, and we love the history angle.
