Are any geodes valuable?

The most valuable geodes are those that contain perfectly formed flawless crystals of amethyst, celestine, calcite, or other rare minerals. Geodes are worth from $2-5 for common specimens and up to several thousand for exceptional several meters.

How do you determine the value of a geode?

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 do I know if my rock is worth money?

The harder a mineral is, the more likely it is to be valuable. If you can scratch the mineral with your fingernail, it has a hardness of 2.5 Mohs, which is very soft. If you can scratch it with a penny, its hardness is 3 Mohs, and if it takes a piece of glass to scratch it, the hardness is 5.5 Mohs.

How do you tell if a rock is a Geode?

What are the most sought after rocks?

*NOT FOR KIDS* BEST GEODES TO CRACK OPEN!!! National Geographic Kit (Explicit)

What is the rarest geode color?

The rarest and most valuable geodes contain amethyst crystals and black calcite.

How do you tell what color a geode will be?

Iron will give crystals a red or purple color, titanium will create blue, nickel or chromium leads to green, and manganese produces pink crystals. While geodes can be naturally colorful some are artificially dyed. These dyed stones often have a brighter, more intense color than what appears naturally.

Are amethyst geodes rare?

Amethyst geodes have been stated to be significantly rarer. However, they are still as common as before. Amethyst geodes have now actually been made rarer, from 1 geode in 30 chunks to 1 geode in 53 chunks. Amethyst geodes no longer generate above Y=30.

How can you tell a real amethyst geode?

An Amethyst gem that is one solid color is most likely fake. Real Amethyst stones will have color zoning including shades of white and blue along with purple. A real Amethyst gem won't have any bubbles but may have threads and impurities beneath the surface. Amethyst is one of the most popular gemstones.

What can you do with geodes?

What is the biggest geode ever found?

The Crystal Cave In Ohio

A massive, celestite crystal lined geode located near Put-in-Bay, Ohio also is said to be the largest geode ever found. It measures a staggering 30 feet (10 meters) long but was larger when it was first discovered.

What is the most common geode color?

The color of a geode depends on the agate layer and the type of crystal inside, both of which come in a variety of colors themselves. Most geodes are brown or white: geodes that are very brightly colored are likely artificially dyed.

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.

Where are most geodes found?

Geodes are found all over the world, though they are most concentrated in desert regions. Other places where geodes are common are volcanic ash beds and areas containing limestone. There are geode collecting sites all over the U.S. in California, Utah, Arizona, Nevada, and Iowa.

What should I look for when hunting a geode?

Recognizing Geodes. Look for rocks with a bumpy texture. When you're searching, you want to look for lumpy rocks. Geodes have lots of bumps and texture to them, so steer clear of any rocks with a very smooth surface.

What is the difference between a Druzy and a geode?

Other Names for Druzy

In some cases, some people may use the term geode to refer to the crystal formations. However, geode refers to the multi-part stone structure, while druzy is technically limited to the crystal formations on the stone base. There are also several spelling variations that you may encounter.

What crystal is in my geode?

Most geodes contain clear quartz crystals, while others have purple amethyst crystals. Still others can have agate, chalcedony, or jasper banding or crystals such as calcite, dolomite, celestite, etc. There is no easy way of telling what the inside of a geode holds until it is cut open or broken apart.

What's the difference between a geode and a 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 a geode and an agate?

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.

Is it a geode or thunderegg?

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.

Do geodes keep growing?

No, you are right. They won't continue to grow. They need to be kept in a supersaturated solution to grow.

How old can a geode be?

Although the geode is embedded in rocks that are about 250 million years old, the crystals themselves are much younger than that. Radioactive dating of some of the oldest suggests they formed less than 5.6 million years ago but probably no more than 2 million years ago, the researchers report this week in Geology .

How much is a geode rock worth?

A geode can be worth anywhere from $5 to more than $1000, depending on its type and location. The price will vary widely based on whether the rock has been cut open because geodes often contain crystals inside of them which make them more valuable when exposed correctly (e.g., cutting along an axis).

What are Tabasco geodes?

Tabasco Geodes, formally known as Illianites, are the world's smallest geode formation. Tabasco geodes have a distinct green (with an occasional red) outer shell (rind) of agate with tiny quartz crystals or drusy quartz in the center vug.
