Spectrolite is a rare, Finnish labradorite gemstone, set apart by its wide range of iridescent colors. Compared to other labradorites, spectrolite gemstones are generally higher-quality and only come from Finland.

But wait, what is labradorite? 

Labradorite is a feldspar gemstone with a dark, translucent base naturally overlaid by a unique iridescence. The glow, or schiller, seems to come from inside the stone, and the phenomenon is named “labradorescence” after the gem. 

So, what makes spectrolite labradorite so special? Today, we’ll answer just that, along with all your other questions about spectrolite’s properties, healing uses, and value. 

Starting with the basics, what is spectrolite stone?

About Spectrolite Stone

First, is spectrolite a gemstone? Yes, spectrolite is a semi-precious gemstone with a dark base and strong, multi-colored iridescence. 

The stone’s gemological name is spectrolite, but this term started as a brand name of Finnish spectrolite. While labradorite crystals from other locales may look similar to spectrolite, only specimens from Finland can legally be called “spectrolite.” 

Many gem experts consider spectrolite the most beautiful type of labradorite. Given the stone’s full array of color flashes, we’d have to agree! Many folks draw parallels between spectrolite’s iridescence and other natural phenomena like rainbows and Aurora Borealis, also known as the Northern Lights. 

While we’re discussing phenomena in the sky, it’s worth mentioning that spectrolite is a star stone for Uranus. It’s also a zodiac stone for Leo, Scorpio, and Sagittarius signs! 

Spectrolite Specifications & Characteristics

Spectrolite and labradorite are feldspar stones, specifically anorthosite plagioclase feldspars. This means their composition is sodium, calcium, aluminum, and silicon. The calcium and sodium content can vary, with calcium between 50-70 percent and sodium between 30-50 percent.

Other plagioclase feldspars include sunstone and andesine. While these gems can show aventurescence (a metallic glittering surface), neither show the signature labradorescence specific to labradorite and spectrolite. 

But what is labradorescence? 

Labradorescence is a type of adularescence only used for labradorite stones. Adularescence is an iridescent play-of-color that appears to emerge from inside the stone, rather than on its surface. Moonstone is another gem with adularescence.

Spectrolite’s labradorescence occurs in part because of twinning, where multiple crystals grow into one another during the gem’s formation. The twinning crystals form alternating layers of two types of feldspars with different chemical compositions. 

Given these factors, light hits the inside of the stone and then diffracts, separating into multiple rays. To our eyes, this separation looks like flashes of different colors. 

Check out the rest of spectrolite’s mineral properties below:

• Mineral family: Plagioclase feldspar

Spectrolite vs. Labradorite

There are two main differences between spectrolite and labradorite: origin and appearance.

Origin

Labradorite’s discovery occurred in Labrador, Canada, while spectrolite was discovered in Finland over a century later. Labradorite stones come from many locales, but only spectrolite from Finland can legally be called “spectrolite.” 

Appearance

Labradorite’s iridescence only shows grays, greens, blues, and sometimes purple flashes. Compared to labradorite, what does spectrolite look like? Spectrolite’s iridescent flashes can show every color of the rainbow. 

The intensity of spectrolite’s labradorescence is also higher than labradorite because spectrolite’s opaque, darker base creates better contrast. That contrast also means spectrolite’s colors are separated more distinctly, while labradorite’s colors tend to blend into each other. 

With the basics covered, it’s time to move into the mystical to examine the spectrolite labradorite meaning!

Spectrolite Meaning & History

Labradorite was first discovered in Canada in 1770, but spectrolite’s discovery wouldn’t happen until 1940 — more than 150 years later. 

Renowned Finnish geologist, Aarne Laitakari, had described a particularly colorful labradorite specimen from Finland and spent years trying to find its source. 

During WWII, Finnish soldiers were gathering stones to create a barricade against tanks, called the Salpa Line fortifications. One of those soldiers was Laitakari’s son, Pekka, who accidentally discovered a spectrolite deposit in Ylämaa among the barricade stones. Of course, Pekka told his father immediately.

Aarne Laitakari paid homage to the stone’s full iridescent display by choosing the name “spectrolite” after the Latin spectrum, meaning “image” or “appearance.” 

Now, Laitakari wasn’t just a geologist — he was also the Director General of the Geological Survey of Finland from 1935 to 1960, among other various endeavors in military, political, and conservation work. 

His widespread influence allowed him to spread awareness about spectrolite. Quarrying the stone began after the war ended and increased during the 1950s. 

In 1973, the first Ylämaa workshop started creating and selling spectrolite jewelry from Finland. Soon after, the Ylämaa mayor established a gemstone center and an annual Gem and Mineral Show. In 1988, the Finnish Tourist Board named spectrolite as the official provincial stone of the South Karelia region.

Meaning & Mythology

The spectrolite crystal meaning is drenched in mysticism and folklore. Given that it’s native to Finland, the stone has Finnish mythology attached to it. 

One myth associated with spectrolite is the “Story of the Rainbow Treasure.” The legend starts after Earth’s creation, as the god of thunder Ukko celebrates his wedding to the mother goddess, Rauni. 

Rauni was melancholy that the Earth was mostly dark rock, so Ukko sent a giant (but brief) storm. Once the storm stopped, a rainbow appeared. Ukko grabbed the rainbow and cast it down to Earth, causing rainbow shards to remain melted into rocks. Those rocks, of course, are spectrolite!

Continuing the rainbow connection, some attach spectrolite’s meaning to the Bifrost Bridge, a rainbow gateway between Earth and the heavens in Norse mythology.

Outside of mythology, spectrolite symbolizes transformation, magic, and light. Sometimes called the “Stone of Mystical Wisdom,” spectrolite is rumored to improve the wearer’s spiritual awareness and intuition. 

On that note, what is spectrolite crystal used for in healing circles?

Spectrolite Healing Properties

The colors and electrical energies inside gemstones can make them useful as healing crystals. Spectrolite is highly valued for spiritual and mystical uses, purported to enhance psychic abilities and awaken the aura.

Since its base is black, spectrolite joins other black gemstones in representing intelligence, protection, and fundamental truths. 

What is spectrolite good for in physical, emotional, and chakra healing?

Physical Healing

Physical healing properties for spectrolite may include increasing energy levels, strengthening the body, and aiding metabolism. The stone is said to regulate breathing, digestion, and high blood pressure. 

Other spectrolite crystal properties for physical wellbeing can include easing pain from arthritis, muscle soreness, and menstrual cycles. It’s said to soothe and relax the entire body. 

Emotional Healing

Emotionally, spectrolite stone benefits anyone suffering from self-doubt or despondency. This mystical crystal can dispel anxiety, inspiring confidence and charisma in those who struggle to speak out.

Additionally, spectrolite gems are said to encourage originality, bring good luck, and reduce the negative effects of deep emotional wounds.

Chakra Healing

Chakra healing is an ancient practice involving opening or balancing your seven chakras, energy centers that align with physical and emotional symptoms. You can use gems as chakra stones to target issues related to a specific blocked chakra. 

What chakra is spectrolite associated with? Spectrolite is great for opening the throat chakra — the center of communication, self-awareness, and truth. 

Feeling disconnected from yourself or afraid of speaking your truth are signs of a blocked throat chakra. You can use spectrolite to open the chakra again, inviting creativity, openness, and self-expression back into your life. 

Spectrolite Gemstone Properties

Gemstone experts examine certain properties in each stone to determine its objective value. Spectrolite’s value factors include color and cut.

Color (Labradorescence)

Unlike other gems, the color that influences spectrolite’s value isn’t present in the stone. Rather, the colors and intensity of spectrolite’s iridescence determine its value.

Since most labradorites will show cool tones like blue and green, maybe with some yellow mixed in, the rarer warm tones are highly desired. Any spectrolite where you can easily see every color in the rainbow shine from within will command the highest value.

The most dominant color flashes in spectrolite are green, yellow, blue, and purple. Brighter flashes mean higher value. 

Cut

Like labradorite, the most common cut you’ll see is a spectrolite cabochon. Faceted cuts are rare, since spectrolite’s perfect cleavage makes faceting difficult. 

Gem cutters may also cut spectrolite into beads or carvings. The most common spectrolite jewelry are bracelets, earrings, or pendants since a spectrolite ring has a greater risk of breakage. 

Before it gets to a gem cutter, how does spectrolite form?

Spectrolite Formation & Sources

Spectrolite forms through a few methods, similarly to other feldspars. These methods include magma crystallizing, high-temperature/high-pressure, and sediment weathering.

During spectrolite’s formation, two feldspar minerals layer over each other: albite, a sodium aluminum silicate, and anorthite, a calcium aluminum silicate. These minerals alternate layers of tiny flakes in a process called lamellar twinning. 

The most common spectrolite rock is a metamorphic or igneous rock, specifically basalt or gabbro rocks.

Mining Locations

As we mentioned earlier, the only stones that can legally be called “spectrolite” come from Finland. However, many sellers mistakenly call labradorites with a wider range of iridescence “spectrolite” when the stones aren’t from Finland. 

Spectrolite is Finland’s most important gemstone export, but it’s still a rare stone. Given its rarity, what is spectrolite worth?

Spectrolite Price & Value

Each region’s spectrolite stone price may differ slightly based on availability. However, spectrolite will almost always command higher prices than labradorite. 

Authentic Finnish spectrolite cabochons range from $20 to $200. Spectrolite jewelry is more valuable — usually costing $175 to upwards of $450, depending on the materials used. Spectrolite rough is the most affordable option, at $0.50-$2 per carat. 

Spectrolite Care and Maintenance

Spectrolite’s hardness is mid-range, but combined with its perfect cleavage, it needs a little extra care. Pressure can chip or crack it, so we recommend opting for less vulnerable jewelry like pendants. You can also choose jewelry with protective settings for extra security. 

To clean your spectrolite crystal, mix mild soap with lukewarm water. Dip a soft brush (like a toothbrush) in the solution, then gently scrub the stone. Rinse your spectrolite, then use a microfiber cloth to carefully pat it dry. 

Store your spectrolite stones or jewelry away from other gems and avoid sudden temperature changes, as this could damage the stone.

Ride the Rainbow with Spectrolite!

Despite its rich history in Finland, you don’t have to be Finnish to appreciate the natural beauty and intrigue of spectrolite. It’s easy to get lost in this magical gem’s spectral colors, but the crystal’s ability to inspire your best will always bring you right back to where you need to be.
