Geodes are sometimes explained as being a phenomenon. There are geologists out there who are uncertain how these geodes are formed. The value of a geode mostly depends on the worth of what is inside of it.

Geodes are highly valued for their content and appearance. 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.

I will take a look at some more detailed pricing of geodes as well as where to find them. If you have a geode already or you are looking to begin the hunt for some, I will discuss how you can sell your geodes.

What are Geodes Worth?

Geodes’ worth ranges dramatically from around $5 to thousands of dollars. Geodes’ price depends on a list of factors, which are the size, scarcity, color, clarity of crystals, their luster, and the presence of flaws. A geode that has perfectly formed flawless crystals of bright color is the most valuable.

You may be a collector, or someone may have gifted you a geode. Either way, you are trying to discover how much your geodes are worth. Unlike diamonds, geodes are not as cut and dry when it comes to pricing and putting a value on them.

There are a few points on a collector or a buyer will use to determine the worth of a geode that include:

  • Clarity

Depending on the geode, the buyer will look for clarity. How clear is the geode? Can you make out every speck inside? Or is the inside a bit murky and unclear?

  • Color

If the color of your geode is darker and richer you will see more value. Darker colored geodes are hard to come by and the amethyst and black calcite geodes can fetch a pretty penny.

  • Size

This one is easy to remember. The larger your geode is, the more valuable it is. Depending on which geode you have, this factor may not work. If it is a rare piece, even the smallest bit of the mineral could be worth somewhere in the hundreds.

  • Flaws Internally and Externally

Should the geode you find have many cracks and splits on the inside and out, you should expect to receive a small compensation. The aesthetics are what truly matters and if the geode looks like it is about to split in two, it will be difficult to sell.

  • Luster

The luster refers to the shine you see on the surface. Most buyers want a piece that sparkles and is not dull.

  • Scarcity

There are some geodes that are rare. Someone could be looking for an amethyst geode that was built or formed a certain way.

  • Buyer’s Price

This part relies on who you wish to sell your geode to. Many buyers and collectors out there will lower how much they pay you, just to sell it for a higher price. If you can, always have your pieces checked out by an expert.

All of the factors above may or may not be used by the buyer when they try to determine a price for your geode. However, since now you know what to expect from a buyer, we can take a deep dive into what makes a geode so valuable.

Are Geodes Valuable?

Geodes are extremely valuable. Their unique formation history and enigmatic appearance make them desirable in every mineral collection. Sometimes geodes are praised for their rare mineral content. Sometimes big amethyst geode specimens are used as luxury interior decorations.

Geodes can satisfy any taste of a mineral lover. Geodes occur in various sizes and colors. You can find a small perfect geode in every mineral shop, however, there are some one-of-a-kind samples that reach several meters in size!

The same with the color. Commonly geodes hide amethyst quartz or rock crystal quartz inside, but occasionally you can find even lapis lazuli tiny blue crystals. Being so universal, geodes are highly desirable on the market.

TIP: It is important to know if the geodes you want to buy are dyed or natural. The price of dyed geodes is often lower than natural ones. That’s why I wrote an article to help you, check it out here:

What Makes Geodes So Valuable?

Geodes are so valuable because they are exclusive creations of nature. Geode is a pig in a poke in the geological world. They are so valuable because nobody knows which minerals are hiding inside before a geode is cut. Minerals inside a geode are truly beautiful. That is why enigmatic geodes are so valuable.

Geodes are valuable because the natural formation of a geode is complex and unique. A volcanic rock produces a gas bubble that has nothing inside of it that slowly starts to form into a rock. The bubble will then begin to harden.

Chemicals such as carbonates and silicates will start to wash into the groundwater. As these chemicals and water start to mix together, the moisture starts to seep through from the outside into the rock.

Now that the moisture is trapped and the temperatures are different on either side of the rock, crystals begin to form.

Tiny crystals will remain on the walls of the rock which is why the rock is hollow when you cut into it. Over time, this process repeats itself as you can clearly see different layers on a geode.

The value of a geode comes from this process repeating itself for thousands to millions of years before someone discovers it.

The color of the tiny crystals inside indicates which type of crystal it is, and this can bring another level of value. These colors can range from:

  • Pink colors mean the geode is Rose Quartz
  • Blue colors can mean the geode is a Gem of Silica
  • Purple colors will mean that the geode is an Amethyst
  • Clear crystals show that the geode is a Quartz Crystal

The color depends on the chemicals that seeped into the groundwater during its formation. For example, if you have blue crystals inside of your geode this means that the rock may contain bits of titanium inside.

Unfortunately, there is no way to tell the inside contents just by looking at the outside of the rock.

There are a lot of geode replicas. However, you can purchase real geodes on some individual’s website or a marketplace meant for geode exchange. Here are a few price points for some crystals:

  • Agate Geodes: A Mexican Agate Geode that weighs around 40 carats may cost you $12. One that weighs 46 carats may cost you $14.
  • Druzy Geodes (Quartz Crystal): An untreated Druzy Geode that weighs 18.5 carats will cost you $17.
  • Amethyst Geodes: A museum-level amethyst that weighs 164 kilos can cost upwards of $15,000. An Amethyst from Uruguay that weighs 3.9 kilos will cost $275.
  • Green Quartz: A cluster of Green Quartz from Uruguay will cost you $2,995.
  • Celestite Geode: This white-looking geode can weigh up to 40 pounds. This amount will cost you $365.

With this knowledge of how the crystals are formed, we can better understand why they are so valuable. There are some tips on how to sell your geode that we will discuss.

Geodes Worth per Gram, Pound, Ounce & Carat

Geodes’ price ranges dramatically. Small plum-size samples can be purchased for about $5, but some geodes are so appealing to mineral collectors, that the prices can hit thousands of dollars.

Geodes are rarely sold based on carat, gram, or ounce weight. They are usually sold as a whole piece based on their value factors more than just weight. However, the price of big interior geodes, whose size reaches the first meters, is usually expressed as a price per kilo.

Here is a table to have an impression of how geode price can be expressed in different units.

UnitGeode Price
per carat$0.35 – 2
per gram$2 – 15
per ounce$5 – 56
per pound$10 – 900
per kilo$90 – 2000
