What Is Arfvedsonite Stone?

Arfvedsonite is a very rare semi-precious gemstone with flashes of blue on a dark base, similar to labradorite. Some of arfvedsonite’s other names include alkali amphibole and soda hornblende. Based on its flashes of color, some also call it “firework stone.”

Though not a birthstone, arfvedsonite with garnet is a common mixture, making it an interesting new twist on the traditional garnet January birthstone. Additionally, arfvedsonite is a zodiac stone for Gemini and a planetary star stone for Mercury. 

The combination with garnet is seen in arfvedsonite with dark red garnet inclusions. These inclusions may sometimes be eudialyte, though, so be wary of sellers trying to upsell you. 

Mineralogically, what are the properties of arfvedsonite?

Arfvedsonite Specifications & Characteristics

The mineral arfvedsonite is a sodium amphibole with the formula [Na][Na2][(Fe2+)4Fe3+][(OH)2|Si8O22]. All those symbols and numbers mean arfvedsonite is composed of sodium, iron, silica, and hydroxide.

Other amphibole minerals include tremolite, hornblende, actinolite, and riebeckite. 

Usually, arfvedsonite occurs as fibrous crystals with a dark sheen, though its silvery blue coloring comes out once it’s polished. The stone may also occur as prismatic shards, often radiating stellates (resembling a star).

The dispersion (or fire) of arfvedsonite is incredibly high, meaning it displays strong colorful sparkles. 

The blue flashes on arfvedsonite may appear similar to play-of-color seen in precious opal, for instance, but they’re actually a result of the stone’s pleochroism. You’ll only see the effect when the stone is polished.

Speaking of, here are the rest of arfvedsonite’s mineral properties:

• Mohs hardness: 5-6

• Color: Dark blue to black with blue color flashes

• Crystal structure: Monoclinic

• Luster: Vitreous (glassy)

• Transparency: Translucent to opaque

• Refractive index: 1.65-1.70

• Density: 3.3-3.5

• Cleavage: Perfect 1-direction on [110]

• Fracture: Uneven

• Streak: Deep bluish-gray

• Luminescence: None

• Pleochroism: Present in gray-violet, yellowish-brown, and blue-green shades

Before we get into the mystical side of arfvedsonite, let’s make sure you know how to identify it when coming across similar-looking stones — particularly astrophyllite.

Arfvedsonite vs. Astrophyllite

There are a few stones that arfvedsonite may be confused with, such as hornblende and nuummite. However, the most common mix-up is between arfvedsonite and astrophyllite.

Astrophyllite is a similarly rare gemstone with a brown to brassy or golden-yellow hue. It’s commonly found in a cream, gray, or off-white matrix (composed of nepheline syenite) where the astrophyllite appears as radiating star-like shapes. 

Similar to arfvedsonite, astrophyllite has a shimmery surface. Both stones can also grow with eudialyte, seen as pinkish-red portions. 

What is the difference between astrophyllite and arfvedsonite?

The first visual distinguishing feature is the color of each stone’s shimmer. Astrophyllite always has a copper, reddish-brown, or bronze shimmer, while arfvedsonite has a blue shimmer.

At a chemical level, astrophyllite is a hydrous potassium iron titanium silicate, while arfvedsonite is a sodium amphibole. Lastly, astrophyllite only ranks at 3 on the Mohs mineral hardness scale, making it softer than arfvedsonite. 

With the mineral side done, let’s get into arfvedsonite’s symbolism and history!

Arfvedsonite Meaning & Discovery

Many spiritual practitioners call arfvedsonite the “Stone of Truth.” The crystal symbolizes self-awareness, purpose, and manifestation. It’s often described as being a “light at the end of the tunnel” of sorts — a companion for anyone feeling lost in life.

The name “arfvedsonite” honors Swedish chemist Johan August Arfvedson (or Arfwedson) who discovered the stone during 1823 in Greenland. Arfvedson is perhaps more well-known for discovering lithium in 1817 when he was analyzing petalite.

Arfvedsonite Healing Properties

All gemstones can function as healing stones, and their abilities can be partly dictated by their coloring. In arfvedsonite’s case, this stone joins other black gems in offering protection, grounding, and positive energies.

That said, the blue flashes in arfvedsonite also evoke the benefits of blue gemstones, such as enhancing concentration and inner peace. 

What is arfvedsonite used for in physical and emotional healing? 

Physical Healing

Unlike other crystals, arfvedsonite isn’t commonly used to treat specific physical ailments. Rather, its purported emotional benefits help bring an overall feeling of wellness and healing that harmonizes the physical, emotional, and spiritual body. 

However, arfvedsonite throat chakra stones may be helpful in resolving physical symptoms of a blockage such as sore throats, neck pain, and thyroid issues. 

Emotional Healing

Crystal healers most often recommend arfvedsonite for relieving anxiety, tension, and melancholy. The stone is said to help you identify what drives you, discover your purpose, and pursue your goal with passion. 

Arfvedsonite is also believed to help you stay calm and collected during difficult circumstances, especially when handling everyday tasks makes you want to scream or just feels impossible. The crystal reminds you what you’re working toward and helps you get there with a positive attitude.

Chakra Healing

Chakra healing is the ancient practice of balancing energy centers (chakras) along the body to resolve blockages. These blockages result in negative symptoms, so opening or balancing the chakra brings the system back into balance so energy can flow.

One method for balancing chakras is by using chakra stones specifically associated with the chakra you’re targeting.

Arfvedsonite crystals are chakra stones for the throat chakra, located at… you guessed it, the throat! It governs how well we know ourselves and how we communicate our truth. 

When this chakra is blocked, you may feel stifled creatively or unable to express what you’re feeling. Opening the throat chakra with arfvedsonite allows you to understand and speak your truth without hesitation or fear.

Arfvedsonite Gemstone Properties

The objective value of arfvedsonite as a gemstone is determined by its quality in the categories of color, cut, clarity, and carat weight. 

Color

Arfvedsonite is always dark, but the extent of streaks showing blue flashes varies from stone to stone. Stones that show more flashes are typically more valuable. 

You may also see flashes of reddish hues; these are caused by ionization. In contrast, portions of reddish to pink hues may be caused by inclusions of garnet or eudialyte. 

Cut

Arfvedsonite is rarely ever faceted, but it can be cut in various interesting shapes. Though cabochons and tumbled stones are the standard, you’ll often see stars, beads, spheres, and even an arfvedsonite tower or skull.

Clarity

Clarity represents how many visible inclusions are present in a stone. In arfvedsonite’s case, inclusions may offer additional value, such as garnet inclusions. 

However, colored inclusions may also deter buyers who want a more consistent coloring, so they don’t always have the same influence on value.

Interestingly, gemologists recently discovered that the dotted inclusions in dalmation jasper (or dalmation stone) are actually arfvedsonite, not black tourmaline as was long thought. 

Carat Weight

As with most gems, rare ones in particular, arfvedsonite’s size will significantly influence its price. Larger carvings with more intricate designs are especially more valuable. 

Moving on, how does arfvedsonite form?

Arfvedsonite Origin & Sources

Arfvedsonite forms over a very long period of time — we’re talking millions of years — inside plutonic rocks. “Plutonic” refers to igneous rocks that form through magma very gradually cooling and solidifying below ground. These igneous rocks are also called “intrusive” types.

Which plutonic rocks does arfvedsonite form inside of? Usually, you’ll find the mineral inside nepheline syenites, granites, or peralkaline pegmatites.

Where does this formation process take place? Only a few select locales!

Mining Locations

Part of arfvedsonite’s rarity comes from its limited sources, most of which have ceased production. 

The arfvedsonite sources are:

• Australia

• Canada

• DR of Congo

• Denmark

• Germany

• Greenland

• Norway

• Macedonia

• Malawi

• New Zealand

• Russia

• South Africa

• USA (Arkansas, Colorado, 

• Zambia

Of course, we have to talk about cost. What should you expect in terms of price when shopping for arfvedsonite?

Arfvedsonite Price & Value

Despite its rarity, arfvedsonite stones are more affordable than you’d think! Starting with specimens of raw arfvedsonite, these run from $25 to $50 typically.

Tumbled stones and palm stones range from $7 to $20, mostly depending on size and amount of blue flashes on the surface. Spheres fetch between $25 to $50, based on similar factors. 

Arfvedsonite towers (also called crystal points) usually cost between $15 to $30, though especially large ones can be $40 to $80 each. Strands of arfvedsonite beads range from around $10 to $20. 

Before we wrap up, you’ll want to know how to care for your gemstone!

Arfvedsonite Care and Maintenance

Arfvedsonite has relatively good hardness, so it won’t scratch too easily. Still, you may want to get jewelry with protective settings for extra safety.

If you have a rough arfvedsonite, caring for the stone takes extra precaution. Since it’s an amphibole (a.k.a. asbestos) mineral, breathing in fibers of arfvedsonite is highly dangerous. It’s best to wear gloves and a face mask when caring for raw specimens.

Polished arfvedsonite, on the other hand, is completely safe because the fibers won’t flake off. You can clean these stones by wiping them down with a soft, microfiber cloth.
