Your post inspired me to learn more about the locality (i only knew they were from spain), and i found a fun article detailing a bit more about it: www.mcdougallminerals.com/blog/the-pyr...

For #MineralMonday I got y'all a classic specimen! Pyrite from Navajún, Spain which produces some of the best specimens in the world. These specimen are textbook pyrite cubes with sharp edges which clearly illustrate pyrite's cubic crystal system.

Heyo! It's #MineralMonday again! Today I have a cool crystal for y'all, Red Beryl in rhyolite from Utah. It is a rare variety of beryl which is colored red from trace amounts of iron and manganese!

$Mineral specimen of Red Beryl in a rhyolite tuff. The Beryl crystal is a purplish red color and forms hexagonal crystals. This particular crystal is largely fractured into three separate parts and is 8 mm in length. This specimen comes from Beaver County, Utah.$

First #artfight attack of the year for @leafora.bsky.social and @sushiikando.bsky.social! I had a blast drawing these two and I apologize for any trauma I inflicted. #TeamMystery #Furry #FurryArt

Traditional artwork of two characters, a minotaur and sheep lost in a labyrinth. The minotaur has brown fur and dressed in a plaid shirt, blue jeans, and a tan sun hat. She has a look of fear upon her face which shows her paralyzing fear of becoming lost. Next to the minotaur is a smaller anthropomorphic sheep sorcerer dressed fine black clothes with a red cape with serpent imagery. She is looking up at the minotaur in an attempt to comfort her.

This is a traditional piece done with ink pens and color pencils.

Happy #MineralMonday y'all! Today I got a fairly new specimen of Cuprite from Arizona! Cuprite is a simple oxide with a cubic structure which is evident in the octohedral red crystals you see in this specimen!

Photograph of a mineral specimen taken by a digital microscope. The lustrous red crystals are the mineral Cuprite, a simple copper oxide. The small crystals display an octahedral habit. The largest crystal seems to show a modified octahdral habit. This specimen comes from Arizona.

It's #MineralMonday! You know what that means. I get to show you a cool rock! Today I got some native copper with some absolute gorgeous oxidation! I had to get a few pictures! This specimen comes from Michigan!

I am happy to report that I will be participating in #artfight this year! Y'all better watch out! >:3 #teammystery #furryart #dnd

Team Mystery character card for Artfight 2026. In the top corner is yours truly, a grey anthropomorphic cat in herringbone cap and red bow tie. He is holding a magnifying glass on his right paw. He is meant to be dressed as a detective. Snapshots of four characters of mine are in the lower boxes. Moving left to right:

Landon - A grey anthropomorphic house cat leaning over two boxes and staring at a shiny green rock. He is my main fursona and the self proclaimed "cat with rocks".

Aaz - A green vampire lizard with brown hair and red eyes. He is dressed in a classic gothic vampire outfit.

Dur (De'err) - An Aarakocra Ranger based off an American Kestral. They are a bit stupid, in an endearing way, denoted by the ellipses above their head.

Kuzu Elahorn: A Fey Wizard. He is a homebrew D&D 5.5e race called a sheepkin which is a shapeshifting sylvan creature. He is dark skinned with white wool-like hair and rose colored eyes.

The card includes several other details about myself and how I intend on playing which I will summarize below.

User - CatWithRocks
I Attack - Anybody! (Especially if you have cool rocks) >:3

Friendly Fire: Yes
Revenge: Yes
Mass Attack: No

Characters I Have: Human, Anthro, D&D OCs

Today for #MineralMonday I got a small piece of Celestine from Turkmenistan! It is only 3 mm in size but with a microscope you can see excellent little crystals.

One of these days I'll make some more mineral pride flags. Here's one I made a few years back (check the alt text for specimen details)

Six photo slices of minerals arranged into a rainbow collage and below that, the six photos of the mineral specimens used for the collage. The crocoite consists of red, elongate crystals, from Tasmania, Australia. The wulfenite is tabular, interlocking orange crystals, from Arizona, USA. The sulphur is a mass of yellow crystals, from Sicily, Italy. The malachite contains curved banding in varying shades of green, from Russia. The azurite is a dark metallic blue resting on top of green malachite, from Arizona, USA. The amethyst consists of a mass of purple, translucent crystals, from Lake Superior, Canada.

All specimens are on display in the Natural History Museum, London.

A throwback specimen for #MineralMonday today! I got this specimen of Microcline var. Amazonite and Smoky Quartz back in June of 2021. Crazy how time flies!

Photograph of mineral specimen. Blue colored amazonite which is a variety of microcline feldspar. It also has a light grey smoky quartz crystal grown with it. This specimen is from Park Co., Colorado.

I once again fashionable late to #MineralMonday. Today I have an Oregon Sunstone which is not only the state's gemstone but has a high concentration of copper in the crystal structure! Not to mention all the optical properties!

I recently got a new microscope which is a huge upgrade for me! I took a photo of a Mordenite I shared several weeks ago for comparison. I'm excited to play around with it some more!

Microscope photo of the mineral Mordenite which are the white acicular crystals. This image was taken with my new digital microscope.

Sorry for a bit of a hiatus. I recently moved, but I am back for another #MineralMonday! Today I got a very interesting fluorite specimen with beveled edges! This contrasts with the typical cubes and octahedrons crystals you typically see.

Photograph of a mineral specimen under a microscope. The mineral is a lavender colored transparent fluorite crystal. It resembles a cube however the edges are beveled in. This is a result of a modified crystal growth. This specimen comes from Arizona.

Been awhile since I've shared some lapidary work. So have a pretty little moss agate cabochon! #lapidary

Sharing some of my personal finds for #MineralMonday today! Quartz crystals with a vibrant red hematite coating. I collected these in July of 2024 from the Pikes Peak Batholith region.

One of my favourites!! You might be used to seeing cubes of fool’s gold but sometimes pyrite is more pyramidal in shape. #MineralMonday #GeoscienceBluesky ⚒️🧪

Specimen of shiny gold coloured pyrite in the shape of a large pyramid with two smaller ones coming off its left side. The faces have small growth marks in them in a squiggly shape. It’s on a black background and part of a plexiglass label below it saying pyrite. At the Sorbonne.

Happy #MineralMonday everyone! Today I got for you a excellent Cinnabar crystal on Dolomite with Quartz from Hunan Province, China. Cinnabar is toxic from it's mercury content so it should be stored safely.

A photo of a mineral specimen. The dark red translucent crystal in the center of the photo is Cinnabar and it is sitting on white rhombohedral crystals of Dolomite. Two clear Quartz crystals are also growing on the Dolomite and can be seen in the top right of the photo and directly beneath the Cinnabar. This specimen is from Hunan Province, China.

Y'all know what day it is! It's #MineralMonday! Today I got another zeolite mineral for you, a spikey balls of Mordenite!

A microscope photo of a mineral specimen. The fine white needles are a mineral called Mordenite and it is in a pocket of the mineral Heulandite. Both of these minerals are in the zeolite group. This specimen comes from Skamania County, Washington.

It's #MineralMonday! Today I got a recent acquisition of Lévyne-Ca. I absolutely adore zeolites and this is probably my favorites! This specimen comes from Oregon (I'd love to find some there one day).

It's #MineralMonday (and I am fashionably late). Today we have a stunning little specimen of acicular Malachite crystals with such a rich green color. I've recently acquired many more microminerals so they will soon be shared!

A photo of a mineral specimen. The bright green needle-like crystals are Malachite, a hydrous copper carbonate. The Malachite is on a dark grey host rock. This specimen was collected in the Democratic Republic of the Congo.

Welcome back to #mineralmonday These are beautiful red Spessartine crystals. This particular specimen comes from Fujian Province, China. Spessartine is a species of magnesium rich Garnet that can be deep red or orange in color. They pop out very nicely with the association of Feldspar and Quartz.
