Malachite is really expensive, Lucky 1. I have a lot of them on my wish list an they are one of the most costlier stones in the market, not cheap. I would most definitely be selling it if I had some on my back yard! lol
I got a whole bunch of Malchites on my wish list, its my go to stone, it's really a beautiful strong robust energy. I used a large Malachite with Reiki energy to heal my daughter from a bad tooth ache she was having. It worked really well temporary before we got her to the oral surgeon.
I had done some research and found Malachite does well with tooth aches, most notably viral and bacterial infections. Its a heavy energy, imo.
A 3 -4 inch Malachite like the one pictured can cost $40-60, the more stronger the green tones, less inclusions(rocky holes) the more the cost. This is a polished one (below with little girls hands lol) I got on Etsy. They also have the natural rough stones and
Fibrous Malachite which is really lovely too. Pic of Fibrous Malachite
