Enhydro Quartz - Tiny Bubbles Make Me Happy

First things first…. ”Enhydros” is a bit of a misnomer. It is a trade name given to minerals that have fluid inclusions, which would be all fine and great except that Enhydros are already a thing* so it can be a little confusing if you are doing a geology/mineralogy deep dive. If you are not looking to get all nerdy and just want to browse for cool stones and jewelry with million+ year old time capsules inside, then asking for/searching for enhydros will probably get you what you’re after. Sorry to start this one off on the pedantic side, but...

Trilobites - Simply The Best

Trilobites - Simply The Best

Geez, where do I even start with trilobites?!  They are my favorite animal and my favorite fossil to work with. I find them to be very adorable and endlessly interesting. I could go on and on about why they are so dang cool, and I probably will in future posts, but let's start with the basics today and I will save the deep dives for another time.  An array of Elrathia kingii trilobite fossils used in my latest collection. Trilobites are an extinct type of ocean dwelling arthropods; animals with no back bones that have a hard exoskeleton, segmented bodies...

Mookaite: Earth's Most Beautiful Ooze?

Mookaite is a type of radiolarite, and radiolarite is made from radiolarian oozes. Simple as that, end of blog post!  An uncut slab of mookaite showing nice color variety. I generally prefer the purple and pinkish colors over the yellow tones, but that's just me ;) Pic from mindat.org Kidding, kidding. This whole saga might be the coolest thing I learned about this year, so I’m going to need to ramble about it a bit more than that. Let’s start with radiolaria, which you may know better as plankton. Teeny tiny plankton, like 0.1 to 0.12 millimeters tiny! These little...

Oolites: they're made from ooids!

Researching this blog post led me down a big ol’ oolitic rabbit hole, and introduced me to some very fun words!*   First cool word - ooid. An ooid is a spherical grain made up of concentric layers of minerals. They are usually smaller than 2mm, if they grow larger than that they become giant ooids - very scientific! To make an ooid you’ll need a shallow sea with lots of dissolved minerals hanging around. It’s not necessary, but often a little bit of organic material like a shell fragment starts the process, and minerals begin to deposit around it, building...

Malachite - It's Just Like Cake Pops!

Malachite’s beauty really speaks for itself, so I am not going to bother with all that. Instead, let’s talk about the fun stuff; chemistry and geology!  A gorgeous example of a malachite stalactite from crystalclassics.co.uk To begin this journey, we need to know about primary and secondary minerals since malachite often occurs as a secondary mineral. A primary mineral is one that forms during the original solidification or crystallization of the rock. For example, minerals that formed from lava flows or deep underground under immense heat and pressure. When these original rocks undergo weathering (either physical or chemical) they are...
