It's not really gemmy, but it's still aquamarine 🩵 Inyo Co., CA. Self-collected from Mesozoic granites. #minerals #mineralmonday #geology

No...Way... (regardless this guy is a well-accomplished geologist)

I present to you the unassuming (yet funny) clay mineral: Dickite. A polymorph of kaolinite (Al-silicate hydroxide). Self-collected from Esmeralda Co., NV. #minerals #mineralmonday #geology

Here's to another nice weekend of being a purple fox 💜 #ASC2026

Another year of @everfreenw.com, another round of origami unicorns (500+ to be exact) 🦄 #EFNW2026

No, it's not a painting, nor AI. It's simply a polished rock 🪨. (Iron-stained alunite from La Paz Co., AZ. Self-collected and polished) #minerals #geology #mineralogy

Yo. (yes, I'm actually smol) #furry #fursuit

Not the best example for #mineralmonday, but it technically is made of minerals, namely olivine and pyroxene. Stony meteorite (H-chondrite). Personal find on a dry lakebed. #minerals #geology #meteorite

Late for #mineralmonday, but right on time for St. Patricks Day. Here be a green sheet silicate, clinochlore, var. seraphinite from Siberia. ☘️ #minerals #geology

The rare, Li-rich tourmaline species Rossmanite, named in honor of the Caltech mineralogist Dr. George R. Rossman, who passed away early this month. Associated with the Li-rich mica trilithionite. Locality: Moravia, Czech Republic. Personal collection. #minerals #geology #mineralogy #tourmaline

Another piece of candy for #mineralmonday 🍭 Elbaite (watermelon) tourmaline fragment. Self-collected from Pala, CA. #minerals #geology #gems

Actually posting minerals on #mineralmonday this time, with a delicate specimen. Vanadinite on mottramite with some barite. Locality: Midelt Province, Morocco. Personal collection. #minerals #geology #mineralogy

Fossil clams so fresh you can make chowder (but really, please don't). Self-collected on the drive to #FC2026. Pliocene (~5 M.y.a.) San Joaquin Formation, near Avenal, CA. #fossil #geology #paleontology

Here it is, hot off the press! Presenting the #PurplePic from @furcon.bsky.social/ #FC2026! Big thanks as always to all the purples that showed up, and especially big thanks to our photographer, @yousqueakgood.bsky.social

Second time being a smol purple fox at #FC2026! I shall continue as such 🦊💜 #furry #FurCon2026

A geologist? AND a furry???? 🤯 (anyway I'll be at #FurCon2026 this weekend and will likely bring minerals & fossils to trade) #furry #fursuit #geology

Starting the new year finding wave-tumbled fossil whale bone from the CA coast. 🐋 Monterey Formation, Miocene epoch (c. 18-6 Mya). #fossil #geology #paleontology

A part of me wants to go to the beach this winter. (Aragonite colored blue from Cu, from Balochistan, Pakistan. Personal collection) #minerals #geology

The forbidden jolly rancher. 🍬 (Elbaite tourmaline from my thesis field site, Pala, CA) #minerals #geology

Guys it's the funny mineral #mineralogy
