I would say that they are all Calcite with Malachite Heimo...


Hello Jordi, visually I agree, but neither specimen fizzed like calcite when put in strong descaler liquid.

Thanks Heimo.
Could you check the fluorescence please? The Tsumeb Willemite tends to have an intense fluorescence under short UV and a regular fluorescence under long UV

Thank you!


Hello Jordi, thanks for the advice. Will do the recommended tests next week, as soon as I get back home from the farm.

Regards.
