CatWithRocks @catwithrocks.bsky.social · 05/10/2026Quick #MineralMonday from me! Have a few hematite included quartz and smoky crystals! Also congratulations to quartz winning the mineral cup! 1456
CatWithRocks @catwithrocks.bsky.social · 04/09/2026Bournonite has my vote today! It is a mineral species I have fallen in love with over the years! #MinCup26 091
CatWithRocks @catwithrocks.bsky.social · 31/08/2026For this #MineralMonday I am getting an early start on the Mineral Cup! First match up is Azurite vs. Smithsonite and my vote will be for Azurite! The specimen I chose is a sample I collected a few years back! #MinCup26 #TeamAzurite 3385
Reposted by CatWithRocksMineral Cup & Ore Cup @mineralcup.bsky.social · 25/08/2026What’s that? For #MinCup26, our 10th year of minerals battling it out for your affections, we drew from ANY year to pick our returning minerals? That’s a lot of joy and heartbreak from one little list! www.mineralcup.org/2026/mineral...mineralcup.orgMineral List — Mineral Cup & Ore Cup 79137
CatWithRocks @catwithrocks.bsky.social · 24/08/2026It's #MineralMonday and today I have some hematite for y'all! A classic iron oxide. I was able to get some beautiful micro photos of this specimen! 1312
CatWithRocks @catwithrocks.bsky.social · 17/08/2026Happy #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! 1171

CatWithRocks @catwithrocks.bsky.social · 07/08/2026That is an interesting observation! There are many signs which indicate the use of chatbots — predictable text patterns, repetitive conversations, and a stagnant tone are a few signs you are communicating with a chatbot. It is important to remember chatbots are not experts in the geosciences. 030
CatWithRocks @catwithrocks.bsky.social · 04/08/2026Phonolites 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! 251
CatWithRocks @catwithrocks.bsky.social · 03/08/2026Psss... it's #MineralMonday... I got you a nice little Galena crystal cluster. I hope you enjoy and have a nice day! 0171
CatWithRocks @catwithrocks.bsky.social · 29/07/2026From my observations, this specimen does not show any twinning. Maybe one day in the future I will find a nice sample with twinning. 110
CatWithRocks @catwithrocks.bsky.social · 27/07/2026Happy #MineralMonday everyone! I was able to pick up a few new specimen this weekend! One of my favorites it this bournonite crystal, a sulfosalt mineral. Hope y'all have a great day! 3224

Reposted by CatWithRocksGreg @suq.bsky.social · 13/07/2026Your 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...mcdougallminerals.com 141
CatWithRocks @catwithrocks.bsky.social · 13/07/2026I thoroughly enjoyed reading through this article! Thank you for sharing 020

CatWithRocks @catwithrocks.bsky.social · 13/07/2026I would love to see if you are able to find it! 010
CatWithRocks @catwithrocks.bsky.social · 13/07/2026For #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. 3384
CatWithRocks @catwithrocks.bsky.social · 06/07/2026Heyo! 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! 1498
CatWithRocks @catwithrocks.bsky.social · 05/07/2026First #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 0182
CatWithRocks @catwithrocks.bsky.social · 29/06/2026Happy #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! 1388
CatWithRocks @catwithrocks.bsky.social · 22/06/2026It'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! 2312
CatWithRocks @catwithrocks.bsky.social · 21/06/2026I am happy to report that I will be participating in #artfight this year! Y'all better watch out! >:3 #teammystery #furryart #dnd 0121
CatWithRocks @catwithrocks.bsky.social · 08/06/2026There is a good chance your piece is also Celestine. The mineral can take on several forms from the tiny colorless crystals to large blue crystalline masses. A good way to check if your sample is celestine is to check the density. Celestine contains strontium which makes samples fairly heavy. 000
CatWithRocks @catwithrocks.bsky.social · 08/06/2026Today 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. 39112
Reposted by CatWithRocksNadine, Hunter of Rocks @nadwgab.bsky.social · 01/06/2026One 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) 312427
CatWithRocks @catwithrocks.bsky.social · 01/06/2026A 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! 4947
CatWithRocks @catwithrocks.bsky.social · 26/05/2026Sunstone 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. 010
CatWithRocks @catwithrocks.bsky.social · 25/05/2026I 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! 11038
CatWithRocks @catwithrocks.bsky.social · 24/05/2026Ladies and gentlemen, we got 'em! #agate #rockhounding 3929
CatWithRocks @catwithrocks.bsky.social · 20/05/2026I 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! 0406
CatWithRocks @catwithrocks.bsky.social · 18/05/2026Sorry 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. 014313
CatWithRocks @catwithrocks.bsky.social · 03/05/2026Been awhile since I've shared some lapidary work. So have a pretty little moss agate cabochon! #lapidary 1191
CatWithRocks @catwithrocks.bsky.social · 01/05/2026You are more than welcome to! I'll answer them the best I can! 110
CatWithRocks @catwithrocks.bsky.social · 01/05/2026Its difficult to say from the photos but from everything I'm seeing it is very likely epidote. 110
CatWithRocks @catwithrocks.bsky.social · 27/04/2026Sharing 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. 5221
CatWithRocks @catwithrocks.bsky.social · 20/04/2026I bestow upon thee a cute little Axinite crystal cluster for #MineralMonday. Have a wonderful day y'all! 1465
Reposted by CatWithRocksErika Anderson @andersonmineral.bsky.social · 20/04/2026One of my favourites!! You might be used to seeing cubes of fool’s gold but sometimes pyrite is more pyramidal in shape. #MineralMonday #GeoscienceBluesky ⚒️🧪 0497
