Description

This highly aesthetic specimen features stacks of multi-generational manganoan calcite crystals in the form of miniature pagodas, with pyrite attractively growing between many of the levels creating a great contrast.

The calcite is a beautiful pale pink and the pyrite has much much more sparkle than could be captured in the photos.

The first generation calcite matrix is white with a strong orange fluorescence visible in longwave UV.

The underside also has a small patch of an unidentified yellow/green mineral, possibly andradite (based on the locality).

With the combination of color, form and sparkle, this is a great small cabinet display piece.

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.
