Description

This spectacular specimen of atacamite comes from its type locality and namesake, Atacama in Chile.

The perfectly formed blades of atacamite are accompanied by balls of bright green pseudomalachite, as well as occasional tufts of olive green libethenite, surrounded by abundant pale green halloysite.

Of course the lustrous atacamite is the main attraction, with many of the crystals in radial formations creating a sparkling display.

This specimen is from an old collection and was mined in the 70's, there are still remnants of the original mounting glue under the base.

Seller's terms and conditions

Please read the dimensions of the specimen, as the size of minerals in photos can be misleading.

To see the details shown in close-up macro photos, you may require a high quality magnifying glass or jeweler's loupe.

Care has been taken to accurately display the colors of the specimen. However, please be aware that computer monitors and phone screens each display colors slightly differently. Differences in light brightness and light source can also drastically alter the appearance of mineral colors. Therefore please be aware that while these photos are accurate and colors have not been enhanced, what you see on your screen may vary slightly from what you see in your hand, and may require specific lighting conditions (usually brighter is better).

Information regarding the specimen's found locality and mineral identification is believed to be correct, however due to the complexities of ID'ing minerals and tracking source locations in rare cases this data may be imprecise.

If you have any questions or concerns please don't hesitate to send a message.
