We had several Show-Me Rockhound members with birthdays in January, and I got thinking about what kind of cake a rockhound would like. I’ve seen some amazing geology-themed cakes but I’m not skilled enough at cake decorating to come close to those. Then I saw these chocolate rocks at Price Chopper and I knew exactly what to do. This is the result. Happy birthday, David, Charley, and Sharon!
Rocks
Thunder Eggs
Some thunder eggs from the personal collection of David Reed. The largest one has purple amethyst crystals on the inside. It was originally from the collection of the late David White, who lovingly polished it by hand to a reflective shine. The medium one is from Oregon. The smallest one is a slab cut from a thunder egg and was from the Show-Me Rockhounds gift exchange.
Christmas Rhodochrosite

Ex. J. Vorpahl Mineral Collection, http://www.themineralgallery.com/rhodoroom.htm
This gorgeous crystal specimen is perfect for Christmas! It has red rhodochrosite crystals on a green matrix (green pyrite?), with pale lavender fluorite cyrstals that look like little snowdrifts. From Steve’s Pocket, Fluorite Raise, Sweet Home Mine, Alma, Colorado.
Antlerite

What is a reindeer’s favorite copper sulfate mineral? Antlerite! Antlerite is named after the Antler Mine in Arizona, but was more often found in Chuquicamata Mine in Chile. That mine has been closed, so antlerite is pretty rare now. This is a close-up of a specimen from the Chuquicamata Mine measuring 7.4 x 3.8 x 2.2 cm.

Thanksgiving Rock Dinner
Happy Thanksgiving! To whet your appetite for dinner, here are some pictures of rocks and minerals that look like food. This is a traveling exhibit, so maybe it will be at a rock show near you.

Start off with a tasty fruit salad.

Gold Sheen Obsidian
This is a gold sheen obsidian from the personal collection of our members M. Mueller and C. Maazouz. Obsidian is an igneous rock, which means it is formed from lava as it cools and solidifies. Obsidian is usually black. However, some types of obsidian have gas bubbles that create a gold or silver sheen like this.
Fall Gem and Mineral Show in KC
We had a great time selling rocks at the 36th Annual Shows of Integrity Fall Gem & Mineral Show in Kansas City! If you missed it, mark your calendar now for the spring show on March 13-15, 2015 (same location, the KCI Expo Center). It will be even bigger!
When you spin our wheel, every spin is guaranteed to win a prize. This year, the prizes included turquoise, shark teeth, and Apache tears.

Happy Agate

An agate dressed up for Halloween, hanging out at the Tucson Rock and Gem Show 2013. Thanks for following us all the way through Agate Month and learning all about these beautiful minerals!

Shadow Agate

Shadow agates are hard to photograph, because it’s more of an effect. When you move shadow agates back and forth, you can see deep, dark areas that appear to move. They look like they are deep inside the stone.
Flame and Frost Agates
These aren’t technically types of agate according to Mindat, but sometimes they will be described this way in rock shops or on rockhound websites. And these pictures are so great I couldn’t possibly pass them up. An agate with red, orange, or yellow plumes in just the right arangement can be called a flame agate, because it looks like fire.

Frost agate describes the cracked finish on these beads (again, it’s not a mineralogical term). They can also be called cracked agate. The frost effect is heightened when they are blue. Whatever they are, I would totally wear earrings made with these beads.
