Fluorite is a mineral that glows a brilliant purple color under black light. Fluorite is incredibly common and can be found in many locations around the world, especially in sedimentary rocks. In addition to its beautiful color, fluorite is very soft, which makes it perfect for lapidary cutting and polishing.
As a matter of fact, its name is derived from the Latin word “fluo” which means “flow”, referring to its ability to be polished very easily when used in jewelry and other decorative arts.

What kind of rocks glow under a blacklight?
Fluorescent rocks, composed of certain rare minerals, are capable of glowing bright blue-white or green-yellow under black light. These glowing rocks are made up of a variety of minerals, and most are found in igneous rock such as basalt, granite, and rhyolite.
One such mineral is Wollastonite, which is a calcium silicate mineral. Another example is Willemite, which is a green-yellow fluorescing zinc silicate. British arrow points made by early Native Americans from the Columbia River area are known to have Willemite inclusions, and so glow under blacklight.
Other minerals that can give off a fluorescent glow when exposed to blacklight include Marcasite, Pyroxene, Apatite, Fluorite, Ulexite and Realgar.
Does quartz glow under UV light?
No, quartz does not glow under UV light. Quartz is a type of mineral that is composed of silica, and while some minerals may fluoresce or phosphoresce when exposed to UV light, quartz does not. Other minerals which do fluoresce under UV light, such as epidote, topaz, and calcite typically have trace elements or impurities which give them this ability.
Quartz, however, is generally too pure to be a target of fluorescence or phosphorescence. It is still possible to have quartz with trace elements that fluoresce, such as barite with minor amounts of strontium, but this is not a normal property for quartz.
Are there rocks that naturally glow in the dark?
Yes, there are rocks that naturally glow in the dark. This type of glowing phenomenon is called “triboluminescence” and occurs when certain rocks are broken or disturbed. When this happens, the rock is emitting light in reaction to the stress placed on it.
Although it is not common and can’t be seen our naked eye, it is scientifically proven to be real. The most popular and most found luminous rock is quartz. Other rocks that naturally glows in the dark are calcite, fluorite, andkyanite.
The light that is emitted from these rocks is not very strong, but when seen under a black light or in total darkness, they can appear as subtle glows in the dark.
What Stone lights up in the dark?
Glow in the dark stones are pieces stones or crystals that have been richly treated with a phosphorescent or “Glow-in-the-dark” powder or paint. This powder absorbs light and then slowly releases it over a period of time, providing a soft glow in the dark.
Some of the most popular types of stones that light up in the dark are quartz, jade, aventurine, and obsidian. Each of these stones has its own unique properties that make it glow in the dark. Generally, stones that have been naturally formed have better properties, meaning the glow is much brighter and lasts for much longer than artificial stones can provide.
Where are Yooperlites found?
Yooperlites are found in the shores of Lake Superior, along the Upper Peninsula of Michigan (known as “the U. P. ”, or “Yooperland”). These beautiful glimmering pebbles, or fluorescent rocks, were only recently discovered by souvenir rockhound Erik Rintamaki in 2017 and have since become a very popular find in this area of the Great Lakes.
To look for Yooperlites, one should head down to the local beaches and search from the shallows to the limits of the lake. Be sure to bring a headlamp or blacklight, and someten wear appropriate beach safety gear if necessary.
Generally speaking, Yooperlite can be found wherever the waves bring the stones, often mixed in with the natural sandstone, agates, and other lake shore stones. It is helpful to remember that Yooperlites can vary in size and can be quite small, so patience is key when looking for them.
Yooperlites are a unique and special find that can’t be seen in other parts of the country and should be appreciated!.
What does a Yooperlite rock look like?
Yooperlites are small, brightly colored rocks found in specific areas of Michigan’s Upper Peninsula. They generally range in size from 1-4 inches and have a smooth, rounded shape. They are most commonly found in beach gravel, and many of them have a blackish-red color to them.
Yooperlites have an orange, green, or yellow fluorescence that shines brightly under a black light, usually one of the colors stands out more than the others, so it’s easy to identify these rocks when you see them.
You might also notice a rusty grid or pattern on a Yooperlite rock; this is caused by the oxidation of iron rich minerals in the rock. Yooperlites are often shiny and full of holes or pockets of gas bubbles, making them fun to collect!.
What natural stone glows?
There are two types of stone that are well known for naturally glowing: phosphorescent stone and triboluminescent stone.
Phosphorescent stone, also known as luminescent stone, occurs because of tiny traces of mineral impurities—such as Strontium Aluminate—that are present within the stone. When exposed to light, these impurities cause the stone to emit light, similar to what a glow-in-the-dark toy does.
This emission is often in a blue-green color and is typically visible for up to 10 hours after it has been exposed to a light source.
Triboluminescent stone is another material that glows. It occurs due to a triboluminescent reaction, which is the release of light energy when two crystals are rubbed together. These stones come in various colors and are known to be some of the brightest luminescent materials found in nature.
These two types of stone can provide an interesting and unique aspect to a living space or can be used for decorative purposes.
Do glowing rocks exist?
Yes, glowing rocks do exist. They are a type of rock known as luminescent rocks, which are rocks that emit light in the form of phosphorescence. These rocks typically come from places with a high concentration of uranium or thorium, causing them to produce a faint light that is visible in the dark.
This light emitted can range from green, blue, yellow, and pink, to even a white-blue hue. Typically, these rocks are found in areas such as mines, dry caverns, and uranium deposits. Scientists have also been able to create luminescent rocks from lab-synthetic ingredients, combining metal salts and ultraviolet light to mimic the effect found in some luminescent rocks.
As a result of this research, it is possible to make glowing rocks of all shapes and sizes, often without the need for uranium or thorium in the composition. However, this process is far more expensive than mining for existing luminescent rocks.
Are glow in the dark crystals real?
Yes, glow in the dark crystals are real and can be used for a variety of purposes. These crystals contain a special phosphor, usually Strontium Aluminate, that absorbs energy from natural or artificial light sources and stores it until dark.
When the lights go off, the crystals emit a soft glow in various colors, lasting up to 12 hours after exposure to light. Glow in the dark crystals can also be recharged and reused, making them a great alternative to standard glow sticks, which lose their luster after a single use.
They can be found in jewelry, toys, night lights, and more, adding a little bit of fun and mystery to any space.
How long does glow in the dark rocks last?
Glow in the dark rocks, also called photoluminescent rocks, typically last for years when stored properly. The intensity of the glow will slowly diminish over time, but the rocks can still produce a faint luminosity for a couple of years.
However, if the rocks are exposed to too much direct sunlight and light from other sources such as general household lamps, the rocks can lose their luminescent properties even faster. To maximize the life-span of these rocks, it is best to store them in a dark area and expose them to light only when desired.
Where do glow in the dark stones come from?
Glow in the dark stones, sometimes referred to as photoluminescence, are created when a particular type of energy is absorbed and retained by a substance before being released as light. A common example of this is the glow given off by fireflies after they have absorbed sunlight.
The source of glow in the dark stones primarily comes from the mineralogy class called phosphor. This class is composed of certain minerals that have been impregnated with luminescent materials, such as zinc sulfide or strontium aluminate; when these minerals absorb energy, they store it and then gradually re-emit it as visible light.
A majority of glow stones used in commercial products are phosphorescent, which means that they need to be exposed to a bright light for about 30 minutes before they will glow for up to 10 hours. Some may require an UV or “black” light to initiate the reaction that causes the stone to glow.
Other forms of glow stones, called tritium stones, do not require being “charged” and will emit more of a continuous, but dim, light over a longer period of time.
Glow stones are available in many different shapes and sizes, as well as a variety of different colors depending on the minerals that have been incorporated into them. They are often found in decorative items, such as jewelry, but can be used in many different applications.
Do sapphires react to UV light?
Yes, sapphires do react to UV light. Under UV light, a natural sapphire will emit a blue glow. This effect is known as “fluorescence,” and the amount of fluorescence a sapphire has is dependent on its type, quality, and treatment method.
An untreated sapphire, for example, usually does not emit as much fluorescence as a heat-treated sapphire. But, depending on its composition and quality, a sapphire could exhibit an intense blue or yellow glow under UV light.
It is important to note that the same effect is found in fake or synthetic sapphires, so ultraviolet fluorescence is not necessarily indicative of a real or natural sapphire when evaluating a gemstone.
How can I tell if my sapphire is real?
There are several ways you can determine if your sapphire is real or not.
The first thing to check is the color of the sapphire. Natural sapphires typically come in a variety of blues and naturally occurring sapphires will have an even color throughout, with no patches or stripes.
If you see too much variation in the gemstone’s shade, this could be an indication that it is fake.
Second, check the transparency of the gemstone. At times, due to inferior treatments and manipulations, sapphires can lose some of their natural transparency. Natural sapphires should be very clear and you should be able to see light through them.
Finally, inspect the sapphire for any signs of wear and tear that may indicate poor craftsmanship. Sapphire should have smooth edges, as well as crisp facets that have not been excessively worn. If the edges are frayed or irregularly cut, it could be an indication that the stone is not genuine.
In order to ensure you have a genuine sapphire, it is important to buy the sapphire from a reputable and certified jeweler. In addition to this, seeking the opinion of an expert in gemstones or a gemologist is a great way to ensure the gemstone is real.
Is sapphire transparent to UV?
Sapphire is generally transparent in the visible and near infra-red (NIR) spectra, but can be slightly opaque to ultraviolet (UV) radiation. Sapphire is a hard, durable gemstone made of aluminum oxide (corundum), with a Mohs scale of 9.
It has a hexagonal crystal structure and is the second-hardest substance after diamonds. In terms of optics, sapphire can be extremely transparent when cut properly, but it is slightly opaque to UV light.
It generally transmits light in the visible and NIR spectra well while blocking most UV light. Consequently, sapphire is widely used in optics, as well as watch crystals and even some forms of armor.
While sapphire is transparent to most forms of light, it is still not quite as clear as quartz and some other types of glass.
