Happy #MineralMonday everyone! I know I have been slacking, but I hope you will take some Gypsum (var. Selenite) as my apologies. This specimen is curled into a "ram's horn" shape!

Phonolites are definitely up there as some of my favorite rocks! Due to the low silica content, you get some especially wacky minerals! Here is a sample of tuperssuatsiaite (brown needles) and villiaumite (red gemmy clusters) in phonolite!

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!

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.

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

Mass Attack: No

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

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.

Sunstone have an optical property known as schiller, which is an silky looking sheen of color within the stone. In Oregon Sunstones this can be anywhere from red to orange to green. Schiller often occurs along the crystal lattice, you can see this in the parallel planes of schiller in mine.

Red lines showing where the planes of the crystal lattice are. These are where the schiller is occuring. The schiller in this specimen is copper colored.

CatWithRocks@catwithrocks· May 25

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!

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

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.
