How do you identify thundereggs?

Though thundereggs appear lke rocks, they can be easily identified by the abnormally round and bumpy brown-gray surface. Usually, thundereggs lie relatively close to the Earth's surface, embedded in the clay of the tuff, where they were formed.

How do you tell the difference between a thunder egg and a geode?

The main difference between geode and thunderegg is that geode is composed of crystals with a hollow inside, while thunderegg is solid. Thunderegg has defined rock and mineral composition. Thundereggs are chalcedony consolidation in rhyolites rocks, while geodes can contain various types of crystals.

What do thunder eggs look like on the outside?

With the appearance of an average looking rough rock on the outside, a careful slice and polish will reveal a hidden core of beautiful mineral deposits. Depending on the minerals present in the area, the inner core of thundereggs can vary significantly from region to region and site to site.

Are thundereggs worth anything?

Their value ranges from about $1 per slice or half egg to well over $100 per slice or single cabochon. A Thunderegg is not actually a rock. It is a structure, sometimes a nodule, sometimes a geode, occurring in rhyolite, welded tuff, or perlitic rocks.

How do you cut a thunder egg?

While most of the work can be done with things found at the hardware store, slicing the egg open will require some sort of saw. Thundereggs 1” or under can be cut with diamond cut-off wheels in a Dremel or flex-shaft but the cut will be rough.

What are thunder eggs made of?

Thunder eggs are spherical objects which form in some types of silica-rich volcanic rocks (e.g. rhyolites). As the volcanic lava cooled, trapped steam and other gases formed an expanding bubble.

How do you find geodes?

To find geodes, look in riverbeds, limestone areas, and volcanic ash beds in countries where geodes are often found, like the United States, Mexico, Brazil, and Madagascar. When you're searching for geodes, look for rocks that are round or egg-shaped with a bumpy texture.

How do you identify a geode crystal?

How can you tell the difference between geodes?

What is the difference between an agate and thunder egg?

Thunder eggs, which are technically known as lithophysae are typically found with solid or near-solid cores of chalcedony or agate, whereas geodes are relatively hollow inside with thinner layers of quartz crystals.

What is the difference between an agate and a geode?

In a lot of ways, agates have inclusions, while geodes are inclusions in the host rock. It's an important distinction to make. But the biggest difference is the fact that geodes are a specific form of mineral, while agates are a specific type of mineral. Any comparison between them should take that into account.

What is thunder agate?

Thundereggs are agate-filled nodules found in various parts of the Western United States. They range in size from 1/4 inch to as large as 5 feet in diameter. Generally, they are about the size of oranges. All are similar on the exterior, but no two are alike in pattern, design or color on the inside.

Thunder Egg from Avon River, Wellington Shire, Victoria, Australia.

What's inside a geode?

The hollow interior often is nearly filled with inward-projecting crystals, new layers growing on top of old. The crystals are of quartz, less often of calcite or dolomite, and sometimes of aragonite, ankerite, hematite, magnetite, pyrite, chalcopyrite, and sphalerite.

Should I donate thunder egg?

In case you are thinking about gifting it, know that it's not a nice gift for anyone. Because only Wizard is the one who gives a positive reaction after you gift him Thunder Egg.

Where can I find thundereggs in NSW?

An area about 25km northwest of Gunnedah, Boggabri is well known locally for agates, chalcedony and thunder eggs. One specimen has hyalite opal and siderite rhombs.

How do you sand and polish thundereggs?

Just dip the attachment into the cerium oxide polish and slowly buff out the agate portions of the thunderegg. Keep following the process until there is no noticeable change in the rock after a buff. Once you have the final, polished, and geometric thunderegg half, find an adequate place to display your work.

How are thundereggs created?

Formation. Thundereggs are found in flows of rhyolite lava. They form in the lava from the action of water percolating through the porous rock carrying silica in solution. The deposits lined and filled the cavity, first with a darker matrix material, then an inner core of agate or chalcedony.

Can you cut a geode with a tile saw?

I selected a medium and large Moroccan geode with a plan in mind, to cut the geodes with a tile saw. This week at my day job, I am laying brick, which mean I have access to a wet saw! Unlike a soil pipe cutter, a saw will give an excellent clean cut on a geode. Well, if you do it right, apparently.

What geodes are worth money?

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.”

How can you tell a geode from the outside?

Look for rocks that have a unique, bumpy texture on the exterior. Geodes are rarely perfectly smooth. The texture of a geode's exterior may have a cauliflower-like appearance. Inspect the surface for any signs of minerals inside.
