Agate is a chalcedony type, a cryptocrystalline form of silica made up mostly of quartz. It’s known for its fine grain and bright colors. It often comes in bands of different colors that look like the rings of a tree trunk.

These bands can be of various colors, from soft pastels to deep, rich tones. They are caused by the gradual buildup of impurities in the silica gel. Agate can also have spots, patterns, or inclusions of other minerals, which add to its unique and often complicated look.

The stone is clear and has many different patterns that make it a favorite among people who like gemstones and jewelry makers. The different colors and patterns emerge from changes in the mineral content of the groundwater during its formation process.

We’ve created an article about how much agates are worth for more information.

Moss agates

Even though it is called “moss agate,” it does not contain natural moss. This beautiful type of chalcedony is known for its beautiful inclusions resembling moss, ferns, or other plants.

Manganese, iron, or other minerals usually form these dendritic inclusions, which resemble branching shapes in semi-transparent stone.

The inclusions’ rich green, brown, or reddish patterns stand out against the chalcedony’s transparent, milky, or bluish background, making a striking contrast that can look like a small forest or landscape inside the stone.

Yes, moss agates can be found in New Mexico. The state, known for its diverse geology and rich mineral deposits, has several locations where rockhounds can find various types of agates, including moss agates.

Fire agates

Fire agate is a chalcedony with beautiful iridescence and mesmerizingly plays with light and color. The shimmering look of this unique gemstone comes from the way light bounces off of thin layers of iron oxide or limonite crystals inside the stone.

Light through these microscopic layers creates a sparkling show of reds, greens, golds, and blues that looks like a plunging fire. Because of how it looks and its rarity, fire agate is a popular gemstone among collectors and people who like to wear jewelry.

With its rich geologic diversity and history, New Mexico is indeed one of the regions in the southwestern United States where fire agate can be found. Particularly in the southern parts of the state, there are several known fire agate localities where enthusiasts have successfully uncovered these radiant gemstones.

Blue lace agates

Blue lace agate is a variety of chalcedony admired for its delicate, lace-like patterns and soft, calming blue hues. These patterns often appear as light blue stripes and swirls, with bands of white, creating an intricate and soothing appearance.

The stone emanates gentle energy, often associated with tranquility, grace, and serenity. Its ethereal beauty and therapeutic properties have made blue lace agate a favorite among gemstone lovers, jewelry designers, and crystal healing enthusiasts.

Blue lace agate is not abundant in the state of New Mexico.

Additional areas you can find agates

Here are some more specific places where you can find agates. We want to help you find these beautiful stones because New Mexico is vast.

Fresh rock exposures

Fresh rock exposures offer an exciting prospect for agate collectors. These newly uncovered areas, whether from natural processes like erosion or human activities such as construction and mining, present a window into the Earth’s hidden geology.

Unlike weathered surfaces, which have been subjected to years of elemental wear, fresh exposures reveal rocks in their more pristine state, often showcasing minerals and gemstones that have remained concealed for millennia.

Streams and creeks

Streams and creeks, with their ceaseless flow and erosive power, stand as dynamic geological agents, constantly reshaping the landscapes they traverse. These waterways serve as natural conveyor belts for agate collectors, unearthing and transporting hidden gems from their origin points to more accessible locales.

As agates form within volcanic rock cavities, the surrounding softer rock gradually erodes, releasing these treasures. Streams and creeks expedite this process, washing away the eroded material and often revealing agates.

Washes and ravines

Washes and ravines, shaped by the intermittent yet powerful forces of water and erosion, offer a unique landscape for agate enthusiasts. As channels, they capture runoff from larger areas, directing water flow and sedimentary cargo through narrowed pathways.

This concentrated movement plays a pivotal role in revealing hidden geologic treasures. As water rushes through, it erodes the softer surrounding rock, potentially unmasking agates that have been encapsulated for ages.
