Rocks

Happy January Birthdays!

Cake and photo by Stephanie Reed

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!

Thunder Eggs

Three round geodes in small, medium, and large. The smallest one is a flat slab with a blue inside and brown outside. The medium one is a hemisphere that's black on the inside and gray on the outside. The largest one is a hemisphere that is purple amethyst crystals on the inside and brown on the outside.

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

A cluster of crystals that has square red crystals on a shiny green surface, with white and lavender puffballs scattered across the whole cluster. A nice display of Christmas colors.

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.

This looks like a fruit salad containing strawberries, blueberries, mandarin oranges, kiwis, slivered almonds, and whipped cream. It is actually rocks.

Start off with a tasty fruit salad.

This looks like a slice of ham (needs gravy, though), a yam with the skin on, and a side of shiny lima beans, but it is actually rocks.

The main course: ham, a yam, and lima beans.

This looks like a slightly translucent slice of pale yellow cheesecake with small red cherries on top. It is actually a slice of rock with rocks on top.

Cherry cheesecake for dessert.

This looks like a huge spread of all sorts of food: bread baskets, muffins, popcorn, nuts, cheese, smoked salmon, fresh fruit, and more. It is actually all rocks.

The whole spread.

Gold Sheen Obsidian

A dull gold oval-shaped stone resting comfortably in a person's palm.  It is highly polished and reflects the overhead lights, and appears to have depth.

As viewed at the November 2014 meeting.

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.

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!

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.
