About Tektite Stone

Much of tektite’s background is tied to meteorites, but is tektite a meteorite?  Not exactly — it’s a semi-precious gemstone said to be the result of meteorite strikes on the earth and a few other origin theories, but more on that in a bit. Tektite’s name is rooted in the Greek word tektos, meaning “molten,” referencing the meteorite’s heat.

Is tektite lucky? You bet!

In numerology, tektite is associated with numbers one and nine. 

While not classified as an official zodiac or star stone, this stellar gem’s connection to the cosmos allows it to resonate with every astrological sign! Tektite can amplify your strengths and weaknesses, no matter your zodiac sign. 

Next, let’s touch on how to identify tektite! 

Tektite Specifications & Characteristics

Tektites are irregular, intricately shaped glassy or crystalline nodules in varying blacks, grays, browns, or greens. A crystal system does not apply because tektite is an amorphous (non-crystalline) mineraloid

You can easily confuse tektite’s physical appearance for obsidian. However, tektite and obsidian have entirely different chemical compositions! You can differentiate them through heating — obsidian bubbles (because of its water content) while tektite doesn’t (because it lacks water).

Here’s an overview of tektite’s mineral properties:

  • Formula: Variable; Silica (75%) + Al, Fe, Ca, Na, K, Mg, Ti, Mn

  • Mineral Family: Mineraloid / Meteorite

  • Composition: Glass

  • Mohs hardness: 5-6.5

  • Color: Black, green, yellowish-green, greenish-brown, brown, colorless

  • Crystal structure: Amorphous

  • Luster: Vitreous to dull

  • Transparency: Transparent to opaque

  • Refractive index: 1.46-1.54

  • Density: 2.21-3.40

  • Cleavage: None

  • Fracture: Conchoidal

  • Pleochroism: None

On another note, tektite’s composition can change depending on its locality. With that said, let’s explore some of tektite’s varieties! 

Types of Tektite Crystals

Today, tektites’ source has been narrowed down to four well-defined strewn fields (or areas of meteorite impact) of different geological ages:

  1. Microtektites — microscopic tektites less than a millimeter in diameter found in ocean sediments and polar ice.

  2. Muong-Nong (or layered) tektites — named for where they were found (Muong Nong in Laos, Vietnam) and range from centimeter- to decimetre-size. This is the only one of the tektite groups occurring on land.

  3. Splash-form tektites — “splash-form,” meaning they formed by melt splashed by impacts; typically shaped like spheres, ellipsoids, teardrops, disks, or dumbbells.

  4. Ablated tektites — formed as solid splash forms reenter the atmosphere at high velocities, becoming partially remelted.

Tektite Varieties

Among the main categories are different tektite variations, many of which are named after their locale. While some varieties are more common than others, they all relate but vary in composition. 

Popular Varieties:

  • Australite

Australite is a dark, often black tektite variety from the Australasian strewn field (Southeast Asia impact crater) and is believed to be 0.77–0.78 million years old.

  • Bediasite

Bediasite, another black variety, is from the North American strewn field (Chesapeake Bay impact crater) in Texas, USA.

  • Darwin Glass

Darwin glass (or darwinite) is a light to dark green, white, or black variety from Tasmania, Australia.

  • Georgiaite

Georgiaite is a yellowish, green, sometimes blue tektite from the North American strewn field (Chesapeake Bay impact crater) in Georgia, USA.

Tektite moldavite is a dark to light, blue to green tektite variety from the Nördlinger Ries Crater in southern Germany. It’s believed to be over 15-million years old.

  • Philippinite

As implied in the name, philippine is a dark variety from the Philippines. Philippinite is believed to be about 710,000 years old. 

  • Zhamanshinite

This is the name given to tektites from the Zhamanshin meteor crater about a million years ago. 

Lesser-known Varieties:

  • Bikolite

Bikolite is a variety from the Bikol area of the Philippines.

  • Billonite

Billonite is a tektite material from Billiton Island (between Sumatra and Borneo).

  • Chinite

Chinite is a black tektite also from the Australasian strewn field. It was found in China, hence its name.

  • Indochinite

Indochinite is a dark, mostly black variety predominantly found in South-East Asia and Australia, and possibly in Canada. The crater of this strewn field is believed to be in Southern Laos.

  • Irghizite

Irghizite is a variety from the Zhamanshin meteor crater in Kazakhstan.

  • Ivorite

Ivorite is a black variety from the Ivory Coast strewn field (Lake Bosumtwi Crater, Ghana). It’s found in the Côte d'Ivoire (Ivory Coast).

  • Uruguaite

A more recent discovery, uruguaite, is a black variety from a new strewn field discovered in 2016.

Phew. That’s a lot of tektites! 

Let’s switch gears and see how this otherworldly gem has appeared throughout history!

Tektite Meaning & History

For centuries, tektite’s meaning and origination have been surrounded by mystery in the world of geology. 

The first recorded mention of tektite comes from China during the T’ang dynasty in 900 B.C. It comes from a book by Liu Sun (a prolific Chinese author) with a title loosely translated to “Notes on the Wonders Beyond the Nanling Mountains in Kwangtung.” 

Sun talks about collecting lei-gong-mo, or inkstones of the Thundergods, after rainstorms. He describes these objects as lustrous, black stones that rang when hit.

After this, tektite seemed to fly under the radar till the late 19th and early 20th centuries. Around this time, Parisian researcher Alfred Lacroix discovered a large tektite deposit in Indonesia, then the Ivory Coast not long after. These discoveries, along with Lacroix’s published research, sparked further scientific interest in tektite worldwide. 

Scientists spent the first half of the 20th century locating and identifying additional tektites and their localities around the globe. As they discovered more deposits, many hypotheses emerged about the origin of tektites’ unique chemical and physical properties. 

In the 1950s and 60s, tektite research made its way to the forefront because of its alleged lunar (moon) origin. Although this theory was eventually debunked, the data collected laid the foundation for much of the tektite research happening today. 

Moving on, what is a tektite gemstone used for in terms of healing?

Tektite Healing Properties

All crystals have metaphysical properties that make them healing stones. Tektite is believed to be a mighty healing tool because of its otherworldly connections. Its cosmic energy provides a multitude of physical, emotional, and spiritual healing powers. 

Let’s see how you can harness tektite’s energy to restore your mind, body, and spirit!

Physical Healing

Tektite can be a superstar physical healer. It can accelerate healing from injury or illness, improve circulatory problems, and aid with fertility.

Emotional Healing

Similar to the physical benefits, wearing a tektite can strengthen you mentally. It may broaden your vision and hone your concentration to see the bigger picture. 

As a vessel of telepathic exploration, it can enhance your psychic abilities and stimulate astral travel or lucid dreaming.

Chakra Healing

Chakra stones hold special energies tuned to one or more of the energy points (chakras) along the body's center. Tektite’s intergalactic vibrations, however, can be placed on any one of them to enhance that chakra’s optimal traits. 

For instance, you can place tektite on the crown (surface of head) to seek clarity and expansion of the mind. If you wish to improve your clairvoyant vision, you can place tektite on your third eye (forehead, between the eyes).

Tektite Gemstone Properties

The value of tektites is dependent on many standard factors of other gems: color, cut, clarity, and size — with some minor variations. 


Most tektites are opaque with dark variations of colors. Translucent and lighter gems tend to fetch higher prices for their obscurity. However, dark colors are still sought after. 


Tektite’s moderate hardness can make cutting tricky. Skilled lapidaries can facet tektite into popular shapes like cushions and fancy cuts — as well as unfaceted shapes like cabochons or decorative carvings. 

Raw tektite is also popular for jewelry and display. The value of raw specimens varies on their shape, size, and visual appeal.  


It’s pretty common for tektite gems to display inclusions of rounded or bullet-shaped bubbles and swirly lines/ridges. These inclusions don’t seem to impact price and are instead a question of preference. 

Carat Weight & Size

You can measure tektite in carats, grams, or millimeters interchangeably. 

Most specimens are quite small (1-5 grams). Larger specimens of tektite are rare. 


While tektite doesn't typically undergo treatments, sellers can enhance the glossy finish through pre-oiling (polishing with mineral or cedar oil). This treatment doesn’t impact tektite’s value or purported healing properties. 

So how are tektites formed anyway?

Tektite Origins & Sources

There is still much to be discovered about tektites! As for its origins, a few theories have been discussed, ranging from atomic explosions to moon rocks. However, most researchers believe meteorites hold the answer.

Is tektite meteorite? Currently, the leading theory is that tektite forms because of meteorites!

According to scientists, tektite is a fused glass caused by a meteorite impacting Earth. This crash brings tremendous heat and pressure. Material from the earth (rock, sediment, etc.) melted on impact, blasted into the air, and fell back to Earth — cooling into the glassy, pebble-like nodules we now know as tektites.

Mining Locations

Where are tektites found? In several pockets throughout the world! You can find tektites in:

  • Australia

  • China

  • Czech Republic (moldavite)

  • Northwest Africa

  • Thailand

  • United States

  • Vietnam

Tektite Care and Maintenance

Don’t be swayed by tektite’s moderate hardness; this crystal is still susceptible to scratches and accidental breakage, so proper care is essential. 

To clean your tektite, simply use a soft brush, gentle soap, and warm water. 

Avoid your tektite coming into contact with:

  • Harsh chemicals/acids

  • Steam cleaners

  • Ultrasonic cleaners

  • Brunt impacts 

  • Extreme temperature changes

With respect to jewelry, your tektite rings should receive protective settings. You should only wear them occasionally. Other jewelry like pendants and earrings shouldn’t be a problem.

Store your tektite in a soft pouch or fabric-lined box away from harder gems.
