How Much are Geodes Worth in UK?

How much are geodes worth

There are various places in the UK, especially Scotland where you can uncover geodes while exploring the nature. Geodes are beautiful rocks with hidden treasures. So, if you are wondering how much are geodes worth in the UK, this guide is for you.

The mesmerizing world of geodes, those unassuming rocks that conceal stunning crystals within, has captivated the imagination of collectors, enthusiasts, and geologists alike. These geological wonders come in various types, each boasting unique characteristics.

A geode can be worth anywhere from $5 to $1000 depending on its type and location where it was found. There are a range of factors influencing the value of a geode. In this article, we will look at the worth of common types of geodes, and factors that determine their price.

What Are Geodes

Geodes are geological formations that house crystal interiors, creating a captivating contrast between their nondescript exterior and the dazzling world within. These formations occur in two main types: volcanic geodes and sedimentary geodes.

Volcanic Geodes

Volcanic geodes, also known as gas cavities or vesicles, form during volcanic activity. As molten lava cools and solidifies, gases trapped within the lava create cavities. Over time, these cavities can become filled with a variety of minerals, forming the stunning crystals found in volcanic geodes.

Sedimentary Geodes

Sedimentary geodes, on the other hand, form through a different process. They originate in sedimentary rocks, which are created by the accumulation and compression of sediment over time.

Within these sedimentary rocks, geodes can form as a result of mineral-rich solutions seeping into cavities or pockets in the rock. Over time, crystals grow within these cavities, creating the beautiful specimens we associate with geodes.

Let’s take a look at how much geodes are worth based on their different types.

Quartz geodes, also known as druzy geodes, are popular for their sparkling, crystalline interiors. These geodes are filled with quartz crystals of different colors like white, clear, smoky, rose, and even purple.

The value of quartz geodes is influenced by factors such as crystal size, transparency, and overall aesthetics.

Larger crystals with a clear or smoky quartz coloration are generally more valuable. The druzy texture, characterized by tiny crystal points covering the interior surface, adds to the allure and value of these geodes.

The most expensive red quartz geode was sold in 2020 by Bohnman’s auction for $10,195. The red quartz geode is extremely rare, making it one of the most expensive in the world.

How much is a quartz geode worth in the UK: A quartz geode can sell for $1 to $5 per carat depending on the color of the crystals inside.

4. Calcite Geodes

Chalcedony geodes, known for their translucent and waxy appearance, encompass a variety of colors, including blue, white, and pink.

The value of chalcedony geodes is determined by factors such as color intensity, transparency, and the presence of unique formations.

Blue chalcedony geodes, for example, are often more valuable than those with paler colors. Chalcedony geodes with intricate crystal formations may also command higher prices.

How much is a chalcedony geode worth in the UK: A chalcedony geode can sell for $2 to $4 per kilo depending on the color of the crystals inside. Blue chalcedony geodes go for hundreds of dollars depending on their size.

Factors that Determine the Price of Geode

Here are some common factors that determine the price and value of geode.


Size plays a significant role in determining the value of a geode. Larger geodes are generally more valuable, especially if they contain sizable and well-formed crystals.

Collectors often seek impressive, statement pieces to showcase in their collections, making larger geodes more desirable and, consequently, more expensive.

One of the world’s largest amethyst geodes is 5 meters in height and it sold for $400,000 in 2020 at an auction by Bonhams. 


Color is a crucial factor in assessing the value of a geode. Vibrant and intense colors, whether in the form of amethyst’s deep purple, agate’s rich bands, or celestite’s delicate blue, contribute to a geode’s visual appeal and market value. The rarity and uniqueness of certain colors can significantly impact a geode’s worth.


The clarity of the crystals inside a geode is another critical consideration. Clear, well-defined crystals are generally more valuable than cloudy or opaque ones.

The transparency of the crystals allows light to pass through, enhancing the visual appeal of the geode and contributing to its overall value.


The rarity of a particular type of geode or the occurrence of unique formations within it can greatly affect its value. Geodes with uncommon colors, crystal formations, or geological features may command higher prices due to their scarcity and desirability among collectors.


The overall condition of a geode, including the state of its exterior and the quality of its crystals, influences its value. Geodes that are well-preserved, with minimal damage or wear, are generally more valuable.

Crystals that are intact, unbroken, and well-formed contribute to the geode’s aesthetic appeal and, consequently, its market worth.

Market Demand

Market demand is a dynamic factor that can influence the value of geodes. Trends in the collector’s market, as well as fluctuations in demand for specific types or colors of geodes, can impact their prices.

Geodes that align with current trends or are highly sought after by collectors may see an increase in value due to heightened demand.


Can diamonds be found in geodes?

Geodes typically contain crystals inside. While it is extremely rare, it is possible for the geode to contain diamond crystals. However, most geodes contain crystals such as calcite, amethyst, and quartz.

How much are fossil geodes worth in the UK?

Geodes with uncommon minerals or fossils are sold on mineral auction sites in the UK for $30 to $500.

Can you tell if a rock is a geode?

Geodes typically have a round or oblong shape, and they have a bumpy surface. These are also lighter than normal rocks of a similar size. Additionally, some geodes are also slightly translucent, allowing you to see a glimpse of the crystals inside.


Now you know how much a geode is worth in the UK. Geodes are not prevalent in the UK, as you can only find them in a few places. From the ethereal beauty of amethyst geodes to the mesmerizing patterns of agate and the sparkling allure of quartz druzy, each type of geode has its unique appeal and market value.

Understanding the different types of geodes, their individual characteristics, and the factors that determine their value is crucial for anyone looking to explore, collect, or sell these remarkable specimens.
