We just received a gigantic shipment of fish fossils, and there are so many to choose from! They range in price from $35 to $100. To appreciate the beauty and detail of the impressions, you really must see them in person 🔍

The all electrically powered cloud chamber is finally finished! Enjoy this video showing the alpha and beta decay particles from this piece of uraninite shoot from the mineral, through a supersaturated alcohol v***r cloud, which leaves trails of condensed alcohol that you can actually see!

I will be presenting at the May monthly Gem & Mineral Society of Louisiana meeting on the topic of radioactivity and radioactive specimens. I will also be unveiling a demonstration piece at this meeting as well (for those of you who know what it is, don't tell everyone else because I'm trying to keep it a surprise). The meeting will be Monday, May 11th, starting at 7:30pm CST in the Geology Building on the UNO campus. So if you'd like to learn a little about radioactivity and radioactive specimens, and see an absolutely killer demonstration as well, come swing by the meeting! Everyone is welcome to attend, and you don't have to be a member to come to the meeting. Since you clearly don't have any excuses not to aren't, we'll see you there! 😁

Hey everybody! Julie and I are going to be bringing the rock saw to the shop tomorrow. We'll have it out from around 12:00pm-12:30pm on Saturday, 3/7, to 4:30pm-5:00pm. So if you have a rock at home that you've always wondered "what does this thing look like on the inside?", then it's your lucky day! Just bring it to the shop between 12:30pm-4:30pm tomorrow, and we'll find out together!

l love, love, LOVE, this humongous pink, fluorescent, dogtooth calcite specimen from Mexico! Just another example that shows why I think calcite is one of the most undervalued minerals in the mineral collecting world!

This is most definitely my favorite calcite in the shop (well, calcite on stibnite to be precise), and is in the running for my overall favorite piece in the shop! it's truly a stunning piece!
