A very nice hunk of agate that was purchased today!

Now that I'm back from the gem and mineral show, here are all the Cool Rocks I came home with!

A cute little coral fossil! He looks like a cauliflower.

A Keokuk geode! These geode beds aren't far from where I live, and it's always fun to have local specimens.

Phosphosiderite! This purple stone comes from Chile. It's so soft that it has to be stabilized with resin before it's cut. This one is a cross section of a botryoidial formation!

Speaking of botryoidial, this Hematite! Botryoidial means it has a bubbly shape kind of like a bunch of grapes. The faces of the bubbles on this pieces are super shiny and metallic.

Dendritic chalcedony, from Turkey! It's a white chalcedony full of dendrites - branching formations of manganese that look kind of like trees!

A cabochon for my cab collection! This one is made from a material sometimes called "ajooba jasper." The pattern is actually a cross section of a bunch of colorfully jasperized bivalve fossils!

Speaking of jasper, this one is Blue Mountain jasper, from Oregon! The circles in this stone are what’s known as an “egg pattern,” and jaspers which have them (Blue Mountain, Imperial jasper, and a few others) are collectively known as “fine jaspers,” the most valuable jaspers in the world.

Hyalite opal! This stuff forms water-clear spheres that look like jelly.

It fluoresces bright green under UV light!

Now to show off this year's haul of awesome agates!

Dryhead agate, from the Bighorn Mountains in Montana! This agate is named after the many bison skulls found in the area. A weird shaped guy with awesome red and orange bands.

Bou Lili agate, from Morocco! I like the name of this one. Soft banding and very subtle, muted colors. I've heard that this locale can produce peachy colors too.

Bear Canyon agate, from the Pryor Mountains in Montana! Agates from this locale have very stark black and white banding.

Red Fox agate, from Argentina! Sometimes this material is also called "crater agate" because the area it comes from is near the crater of an ancient volcano.

A Blue Sky thunderegg, from New Mexico! Thundereggs from this locale often have this two pointed, saucer-like shape.

It fluoresces really brightly!

Dulcote agate, from England! The bands of this agate are full of calcite, which gives them a strange, distinct texture.

Malawi agate, from Malawi! See all the cracks in it? Almost all Malawi agates have them. Frequent earthquakes due to the East African Rift cause these agates to crack and fracture.

Paint Rock agate, from Paint Rock Valley in Alabama! This agate is very rarely banded, and usually just contains swirls of red and yellow color.

A big, unpolished slab of Montana agate! This agate is known for its clear banding and black lines and spots, which are caused by manganese dendrites.

It's best viewed with some light behind it!

A smaller piece with really amazing dendrites!

Here it is backlit!

Fighting Blood agate, from Hebei Provence in China! This locale is known for its super saturated reds and yellows. This piece has purple amethyst crystals growing inside! They didn't photograph well; they are much more purple in person.

A really weird Fighting Blood agate! This one lacks the bright colors typical of this locale, but makes up for it with that super cool spiderweb pattern!

And finally, as is tradition, I came home with some Ethiopian opals! Here are the five I got this year.

And that's everything I got at the show!

Some Art Vocabulary

Abstract - Simplified, intended to capture an aspect or essence of an object or idea rather than to represent reality.

Amber - Tree resin that has become a fossil. It is semi-transparent and gem-like. Amber is used in jewelry today as it has been for thousands of years.

Amulet - Object, organic or inorganic, believed to provide protection and turn away bad luck. Amulets were often worn as jewelry in antiquity.

Anneal - To heat metal to make it soft and pliable.

Black-figure - Technique of vase painting developed in Greece in the 7th and 6th centuries BCE and adopted by the Etruscans. Figures are painted on a reddish clay vase in black silhouette and details are then cut away with a sharp point down to the red below. Sometimes artists added additional colors, especially purple-red and white.

Bronze Disease - Corrosion of a bronze object that cannot be permanently stabilized. Without special care, an object with bronze disease will continue to corrode.

Bust - Portrait of a person including the head and neck, and sometimes the shoulders and part of the chest.

Cameo Glass - Glass produced by layering two or more colors of glass. Generally, an upper layer of white stood out against a contrasting lower background, usually blue.

Cameo Stone - Hard stone, such as agate, naturally layered with bands of color. Artists took advantage of the layers to carve figures or decoration from an upper layer (or more than one), leaving a background layer of a different color.

Cast - To make in a mold from liquid metal. A cast object can be hollow or solid.

Chasing - Technique of adding definition and details to an image or design on metal from the front using blunt and sharp tools.

Conservator (of antiquities) - Professional responsible for preserving ancient objects and materials. Conservators usually have a general knowledge of chemistry and of ancient art-making practices and are often specialists in one material. Among many other responsibilities, they conduct technical and historical research and oversee preventive care such as climate control.

Contrapposto - (”opposite” in Italian) Pose of a standing figure with most of the weight on one leg and the other bent. This causes hips, shoulders, and head to shift in order to balance the body. One arm is often higher and one lower.

Emery - Hard, dense rock rich in corundum, found easily on the Cycladic Islands. A powerful abrasive for grinding and smoothing other stones.

Encaustic - Technique of painting using colored pigments mixed with wax. The waxy mixture was worked with a tiny spatula.

Gild - To apply a thin layer of gold foil or liquid gold (gilt) to create the look of solid gold.

Iconography - Study of and use in art of repeated images with symbolic meaning.

Incise - To press or cut into a surface (stone, metal, clay, wood) with a sharp tool to write text or create fine curving and linear details.

Inlay - To decorate an object by inserting a piece of another material into it so that it is even with the original surface.

Low Relief - Method of carving figures or designs into a surface so that they are raised slightly above a flat background.

Mosaic - Technique and type of artwork. The technique is to arrange cubes of stone, glass, and ceramic to form patterns and pictures in cement, usually on a floor. The artwork is the final story or decoration made of cubes.

Mummification - Process of preserving a body by drying it. The Egyptians removed internal organs and put natron, a natural mineral mixture, on and inside the body. This absorbed moisture and prevented decay.

Palmette - Stylized palm leaf used as decoration in ancient Greek and Roman art and architecture.

Pentelic - From Mount Pentelicus, near Athens. An adjective that mostly refers to the beautiful white Greek marble marble in its quarries.

Portrait - Image of a person, usually the head and face. Some portraits include part of the chest or show the whole body. The image may closely resemble a person or emphasize, idealize, or invent characteristics.

Repoussé - Technique of raising the outline of a design on metal by repeatedly heating and softening the metal and pushing the desired shapes into it from the back with a blunt tool.

Sarcophagus/Sarcophagi (pl) - Stone coffin, often decorated on the sides with mythological scenes carved in relief, sometimes with the image of the deceased person or couple on the lid. Used in Imperial Roman times from the early 100s into the 400s CE.

Stele/Stelai (pl) - Upright stone or wooden slab or pillar used to honor a person or mark a place. Often an inscribed grave marker or a boundary stone. (Also called stela/stelae.)

Syncretism - Blending of elements of different cultures, often resulting in new imagery or new interpretations.

Tessera/tesserae (pl) - Pieces of stone or other hard materials cut into squares or cubes to make mosaic art.

It's a stick agate. I can also call it quartz and banded agate. I think it's more accurate to call it blue agate.
