To learn more about Manganocalcite for jewelry, read our:

• Color: white to rose-colored, orange to pink under UV light

• Origin: Peru

• Mining/Collection: So far, there has been only one mine for manganocalcite in Peru. Over the last couple of years, we noted the quality of the material getting worse and worse. It showed less fluorescence, more white chalky contents, holes, and black impurities as well as less good color. All this is a clear sign of a mineral vein being fully exploited and disappearing. Now we have good news. A new vein of manganocalcite was found in Peru providing top-quality material with super fluorescence, great banded color, without chalky parts or black impurities, and no porous material full of holes.

• Crystal Form/Structure: Solid manganocalcite is soft and brittle and requires very careful cutting.

• Hardness: 3-4 on the Mohs scale,

• Chakra: Mangano calcite can help to align the chakras and can help open up the heart chakra.

• Astrological Sign: Taurus and Libra

• Ethically mined and produced: Gemrock only buys from legal providers (paper trail). Our Cabochons are exclusively produced by our in-house gemcutters.
