Beautiful malachite slice with interesting drawing, polished on both sides, originated from Zaire.
When tinning should be very careful, it does not tolerate acids, sometimes other soldering means, and projistoty.
Malachite is a stone of emotional protection, sometimes it is also given to children against bullying (but not small, who like to stick everything in their mouths! Never give it to them) but its function is mainly to set personal boundaries, so it is to say NO, Enough or on the contrary, yes. It is also a stone suitable for sacrificial mothers and grandmothers, who are often fascinated by his green drawing. The subtle layers that have been added for hundreds and sometimes tens of thousands of years have the power you will love.
