I do not have experience with any Covellite tumbles as they are so hard to get I usually sell the one or two I get quite quickly. When I investigated it I found it “has high copper content, which also makes it useful in easing rheumatism and arthritis symptoms. This stone can be very useful against microbial infections, as well as yeast.”
This crystal stimulates the higher chakras assisting the connection to guides and other divine sources of wisdom. Covellite helps to express spiritual information and knowledge clearly” for example through writing. “It is known as the stone of release and transformation and said to enhance communication skills and stimulates positive outlook. ”
As I write this doing the research it is definitely creating energy around my eyes, forehead, nose, bridge of nose (I can’t remember the chakra’s name) and third eye. I feel my breathing has improved as its helped my sinus. It is very strong energy making itself known despite the more earthy crystals that are also beside me. I feel it could give me a head ache yet it has not (at this point!)
It is also called Covelline, is this covellite tumble for you? It is hard to find so once gone, not sure if I will find again.
