Yes, when you break open a geode, the minerals on the inside have a shiny appearance, some moreso than others depending on their composition.
== == It depends on what's inside. Large amethyst geodes can go for thousands. Baseball sized geodes with non-spectacular quartz or calcite crystals can be purchased for $4-$12. Geodes with uncommon minerals that are sold on mineral auction sites range in price from $30-$500. Golf ball sized geodes, uncracked, are sold for about $2 at shows.
Yes, geodes can be found in any state.
yes
Hydrolyte geodes have been found in the South American country Brazil.
Geodes are secondary structures that occur in sedimentary and igneous rocks. Geodes are hallow on the insde. They are spherical to oblate in shape. Most contain clear crystals, though some may contain colored crystals. Geodes are common in the U.S. states of Indiana, Iowa, Missouri, Kentucky and Utah, and the countries Mexico, Brazil, and Namibia.
They look like rock on the outside but a gift on the inside
Thunder Eggs are rocks containing crystals inside them. This is what makes them geodes.
the only place i have found them in illiinois is inside of geodes.
yes there are some rocks that are round called geodes these rocks are hollow on the inside and have crystals inside them

how big can geodes be
The igneous geodes are classified as intrusive and the sedimentary geodes are classified as chemical based on properties.

yes
Geodes are sphere-shaped stones which are partially hollow, and often lined with sparkling mineral crystals inside their cavities. It usually takes 240 million years to form a geode.
Geodes are usally found in dry areas such as deserts.
Yeah calcite is in geodes. you can find some in stores or you can go on the internet and there is proof that there is calcite in geodes if you go to google.com and go to images and type in calcite in geodes ask wiki answers for more info :)!!!!
