By Dr. Keith Jackson - Geology PhD


Agate is a colorful, eye-catching type of rock that forms when silica from groundwater fills in cavities and cracks in other rocks. This process happens over millions of years, layer by layer, giving it its one-of-a-kind, beautiful bands.

So, what does agate look like? Imagine stripes and bands of different colors, like layers of a cake, but much harder! These layers can be all sorts of colors: red, blue, green, yellow, and more. Each piece of agate is like a one-of-a-kind painting.

In this article, we’ll explore the different types of agates and how uniquely beautiful each of them is. You’ll be amazed at the wide variety of this natural wonder and even the vastness of its patterns and banding.

Remember, no two pieces of agates are exactly alike. So, get ready to be mesmerized by the photos of the vast agate types here. Let’s get started!

The 22 Different Types Of Agate And What They Look Like

Agates are not just pretty— they hold great value for collectors, artists, and anyone who loves natural wonders. The value of agate represents millions of years of Earth’s history, locked in vibrant colors and patterns.

When we explore its types, we discover a world of natural art, with each type offering a unique glimpse into the incredible processes that shaped our planet.

Blue Lace Agate

Blue lace agate is like the soft, sky-blue waves with lines that swirl and twist like delicate lace.

Its pattern comes from slow-forming layers of quartz, which create those beautiful, lace-like bands.

The bands of this agate type are often in shades of light blue, white, and sometimes a bit of grey. It’s different from other agates, which usually have more intense colors and stronger patterns.

The value of blue lace agate lies in its soft, tranquil look and the feeling of calm it brings. It’s often used in jewelry or as a decorative stone.

Where you can find blue lace agate

If you’re wondering where to find agates, particularly this type, blue lace agate is mainly discovered in places that have a lot of volcanic activity. It forms in the cracks and cavities of the rocks that are affected by this volcanic action.

These locations are often remote and can be quite rugged. Among them are Namibia, in Africa, and Brazil. Another interesting location is the USA, especially in Oregon and Idaho.

Moss Agate

Instead of having the typical banding for which the different types of agates are known, moss agate has green inclusions that look like moss or trees.

These green patterns aren’t real plant material, though. They’re minerals like chlorite or iron oxide.

In some cultures, this type of agate is known as the “gardener’s stone” because of its green, plant-like appearance. It’s believed to help plants grow.

The price of moss agate can vary. It’s often quite affordable, but the more distinct and picturesque the green patterns, the more it might cost.

Where you can find moss agate

You can find moss agate in environments where volcanic rocks are present. In the USA, Montana, Wyoming, and South Dakota are known for having them.

India is another country where it’s commonly found. The regions in this country that have moss agate often reveal pieces with exceptionally vivid green patterns.

In these locations, you’re likely to find moss agate in riverbeds or along the edges of volcanic fields. If you need more information on the best rockhounding locations, check out our article.
