Merry Christmas, Feliz Navidad & Happy Holidays to everyone! I posted this tree a couple of years ago, but decided to decorate it this year! Aragonite/cave calcite from "Santa" Eulalia, Chihuahua, Mexico, with some willemite & calcite sprinkles from Franklin, NJ. Shown under short wave ultraviolet and white light.
Terlingua Calcite (pink, lilac, blue) with associated calcite from the Little 38 Mine in Terlingua, Texas. It shows multiple colors from multiple generations of calcite growth. A beautiful rock that doesn't have a bad side! Some of the yellow fluorescing calcite phosphoresces (glows in the dark) under all wavelengths, some of it doesn't phosphoresce at all. None of the orange fluorescing calcite phosphoresces. The bits of Terlingua Calcite phosphoresce after exposure to both short wave and mid-wave UV. Shown under long wave (pink), mid-wave (lilac), short wave (blue) and white light.
Good evening and I am a collector of rocks and minerals.and I like your rocks.
I'm happy that you like my rocks! Sharing them for others to enjoy is the reason I post them!
Fluorescent mineral display at the 65th Annual Dallas Gem & Mineral Society Show. Long wave ultraviolet on the left, short wave on the right. Pic 1 shows both the long wave and short wave UV lights on. Pic 2 shows just the long wave. Pic 3 shows just the short wave. Pic 4 shows the rocks after all the lights have been turned off. They glow in the dark! Pic 5 shows what they look like under regular, ordinary, boring white light. Pic 6 shows seven rocks that are tenebrescent. Can you find them?
Terlingua Calcite with hyalite(?) from the Little 38 Mine, Terlingua, Texas. The hyalite (or chalcedony) is a relatively rare association with about 5% or fewer of the specimens having it. This one has a nice sprinkling on the display side and some on the other sides as well. It also has a nice rim of orange fluorescing calcite along the top edge. Shown under short wave, mid-wave, and long wave ultraviolet, and white light.
Terlingua Calcite with associated yellow fluorescing calcite from the Little 38 Mine, Terlingua, TX. The Terlingua Calcite phosphoresces under short wave and mid-wave UV, while the associated yellow fluorescing calcite phosphoresces in all wavelengths. A nice palm-sized piece. Shown under long wave, mid-wave, short wave UV and white light.
are you aro? Bc if so I love/hate your name so much it makes me laugh and makes me infuriated at the same time
aro? Love me, hate me. It makes no difference. To each his own. I like cool rocks.
Hi Rock maniac, i like to ask for your permission to use a picture of fluorescent minerals.
We are making a fluorescent mineral set for children and wanted to use a picture that can illustrate how pretty fluorescent minerals can be. Yours is certainly one of the best I could find.
Yes, I'm happy to allow you to use my pictures for educational purposes.
Mixed fluorescent minerals from the Beltana Mine (Puttapa Zinc Mine), Leigh Creek, North Flinders Ranges, Flinders Ranges, South Australia, Australia. Pictured under short wave ultraviolet and white light.
Benitoite from the Benitoite Gem Mine, San Benito County, CA, under white light and short wave ultraviolet. Benitoite is California's State Gemstone. It crystalizes in the rare ditrigonal dipyramidal crystal class.
Terlingua Calcite from the Little 38 Mine in Terlingua, Texas. All of the fluorescent minerals in this rock are calcite. Shown under long wave ultraviolet, mid-wave ultraviolet, short wave ultraviolet and white light. This one weighs over 8 pounds.
Here's wishing everyone a Merry Christmas and Feliz Navidad with an aragonite/cave calcite from "Santa" Eulalia, Chihuahua, Mexico. Shown under short wave ultraviolet and white light.
Fluorescent mineral display at the 64th Annual Dallas Gem & Mineral Society Show, November 20-21, 2021. The case is illuminated with long wave ultraviolet light on the left side, and short wave ultraviolet on the right. Note that many of the minerals in the center of the display exhibit different color responses under long wave vs. short wave.
Calcite from the Buckwheat Dump at the Franklin Mineral Museum, Franklin, NJ. Pictured under long wave, mid-wave, and short wave ultraviolet, and white light.
Black/gray/brown scheelite crystal from the Tae Hwa Mine, North Chungcheong Province, South Korea. Scheelite is an ore of tungsten. Shown exhibiting the classic blue fluorescence under short wave ultraviolet light, under white light, and showing the red fluorescence that is sometimes seen under mid-wave ultraviolet light. The nearly equilateral triangle edges measure approximately 1 3/4 inches or 4.4 cm.
Fluorite on hyalite reportedly from the La Lupita Mine in Durango, Chihuahua, Mexico. Pictured under short wave + long wave ultraviolet, white light, short wave only, and long wave only. The hyalite is best under short wave uv and the fluorite is best under long wave uv.
Fluorite from the Ojuela Mine, Mapimi, Durango, Mexico. Pictured under Long wave ultraviolet and white light. The widest face of the biggest crystal is 2.9 cm.
