Description

Here is a very aesthetic combination of copper minerals in their massive form, consisting of light blue chrysocolla, mid-blue azurite, and green malachite, accented by beautiful dark red cuprite.

Adding to the variety of colors are patches of an unidentified yellow-green coating, which surprisingly is slightly radioactive (very minor, no need for precautions), possibly carnotite.

This fascinating specimen also has a few areas showing botryoidal growth, and small patches of quartz throughout the piece add some sparkle.

The specimen conveniently has a flat sawn base, making it a perfect cabinet display piece requiring no stand.

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.
