Amber is fossilized resin that prehistoric trees secreted as a protective response to damaged bark. It comes in a wide variety of colors, the most common of which are yellow, orange, and brown. Genuine amber exhibits distinct fluorescence under black light.Locality: IndonesiaSize:  3–4 cmshort-wave (254 nm): gray-bluelong-wave (365 nm): intense light blueDue to technical limitations, the colors in product photos may differ slightly from those of the original specimen.Our images are intended as reference; upon purchase you will receive a specimen of comparable quality.

Calcite, also known as limestone, or double spar, is one of the most common minerals on Earth. Colorless and transparent in its pure form, this carbonate mineral — often due to the presence of rare earths — glows yellow to orange-red under UV light, but can also exhibit other colors.

The name Cerussite derives from the Latin word cerussa, which is why it was formerly known as white lead ore or "white lead", the key ingredient in now discontinued lead paints.It is a common mineral and, with over 80 known crystal forms and around 400 combinations, one of the most diverse minerals in terms of crystal forms.short-wavelength (253 nm): grayish-yellowlong-wavelength (366 nm): lemon yellowSize: approx. 3 x 4 cmDue to technical limitations, colors in product photos may differ slightly from those of the actual item.Our images are intended for reference;  upon purchase you will receive a specimen of equivalent quality.

Originally known as fluorspar, fluorite was the starting point for the phenomenon of fluorescence, which was first discovered and named in 1852 by the Irish physicist George Stokes. As the first officially recognized fluorescent mineral, it ranks at the very top of the list.Despite its widespread occurrence worldwide, this mineral almost always fluoresces.Size: approx. 3 cmshort-wavelength (253 nm): blue-violetlong-wavelength (366 nm): blue-violetDue to technical limitations, colors in product photos may differ slightly from those of the actual item.Our images are used as a reference; upon purchase, you will receive a specimen of comparable quality.

Hackmanite, which can temporarily change color when exposed to UV or sunlight,is a mineral in the sodalite group. Under ultraviolet light (long-wave or short-wave UV light), hackmanite glows in striking colors. This natural stone is very popular among mineral collectors. It is sometimes referred to as a “natural luminescent material.”Size: approx. 3 x 4 cmshort-wavelength (253 nm): pink-redlong-wavelength (366 nm): orangeDue to technical limitations, colors in product photos may differ slightly from those of the original product.

This relatively rare mineral belongs to the sodalite group and exhibits a very beautiful fluorescence under black light, with the intensity depending on wavelength and localityof the specimen.Size: approx. 3 x 4 cmShort-wavelength (253 nm): faint orangeLong-wavelength (365 nm): bright orange – yellow-orangeDue to technical limitations, colors in product photos may differ slightly from those of the actual piece.Our images are intended as reference; upon purchase you will receive a specimen of equivalent quality.

Hyalite, also known as water opal, is a mineral characterized by a clear, colorless to slightly colored structure and a distinctive vitreous luster. Hyalite forms through hydrothermal processes near the Earth's surface, often in the cavities of igneous rocks such as basalt.Locality: Erongo, NamibiaSize: approx. 2–3 cmShort wavelength (253 nm): greenLong wavelength (365 nm): pale greenThe photo was taken using long-wave lighting.Here’s a short video about it on Instagram...and here on FacebookOur photos are inteded as reference.

Rubies are a red variety of the mineral corundum (Al₂O₃). They derive their iconic color from trace amounts of chromium. Ruby crystals are valued not only in jewelry but also in lasers, where their fluorescence is amplified by optical pumping and emitted coherently.Size: approx. 3 x 4 cmlong wavelength (365 nm): pink to dark redDue to technical limitations, colors in product photos may differ slightly from those of the original product.Our images are provided for reference; upon purchase, you will receive a specimen of comparable quality.

As demand rose during World War I and World War II, miners used short-wavelengthUV lamps in the dark to detect scheelite—an important ore for extracting tungsten fromrock. The mineral often sparkles like a starry night sky.Under long-wavelength UV light, pure scheelite shows no fluorescence.Size: approx. 3–4 cmshort-wave (254 nm): white-blueDue to technical limitations, colors in product photos may vary slightly from those of the original specimen.Our images are used as reference; upon purchase, you will receive one specimen of equivalent quality.

Over time, ‘tremolite’ has often been used as a generic term for fluorescent minerals belonging to the asbestos group. Manganocummingtonite, anthophyllite and tremolite are virtually indistinguishable from one another in the field and all belong to the amphibole group of silicate minerals.Regardless, they are stunningly beautiful fluorescent specimens!Size: approx. 3 cmshort-wavelength (254 nm): intense orangelong-wavelength (366 nm): orange–pinkColors in product pics may vary from those of the original specimen due to technical reasons.Our photos are inteded as reference; upon purchase, you will receive one specimen of equivalent quality.

Willemite, a zinc silicate, is known for its extremely high fluorescence under short-wave UV-light, where it can show various green colors. In daylight, willemite occurs in a wide variety of shapes and shades, ranging from spring green, gem-like crystals to red masses. Willemite is also often phosphorescent.Size: approx. 3–4 cmshort-wavelength (253 nm): bright greenlong-wavelength (366 nm): gray-greenDue to technical limitations, colors in product photos may differ slightly from those of the original piece.

Witherite is relatively rare and is a zeolite mineral. Most witherites exhibit rather unremarkable shades of white to gray; polished specimens are usually colorless or white.They can also exhibit pale shades of yellow, green, or brown.Size: approx. 3 x 4 cmshort wavelength (254 nm): yellowishlong wavelength (365 nm): faintly yellowish to bluish-whiteDue to technical limitations, colors in product photos may differ slightly from those of the actual specimen.Our images are intended as a reference; upon purchase, you will receive a specimen of comparable quality.

Yooperlite – the glowing secret from MichiganSize: approx. 2-3 cmLocality: MichiganYooperlite is an extraordinary type of rock from northern Michigan, discovered only a few years ago. It is especially famous for its bright fluorescence under UV light, usually glowing in vivid orange or yellow. This effect is caused by the mineral sodalite, which is embedded within the volcanic host rock.The name “Yooperlite” comes from the residents of Michigan’s Upper Peninsula—known as “Yoopers”—where these spectacular stones are found along the shores of Lake Superior. Thanks to their intense fluorescence, they quickly became highly sought-after collectibles.Yooperlite brings together geology, natural phenomena, and the excitement of collecting—making it a true highlight for anyone who loves fluorescent minerals.Colors on photos may slightly differ from the original piece due to technical reasons.Pictures serve as an example.
