Kaznakhtite is a relatively new mineral designated by the IMA as No. 2021-056. On this specimen there are two deep green large crystals, 3mm and 2mm, in size in purple Stitchite. I am told this was a very limited find and thus very rare.
Kaznakhtite is a member of the Hydrotalcite supergroup and thus will be associated with similar species such as its matrix (Stitchite), Iowaite, Pyroaurite and Woodalite. These are hydroxides and carbonates of magnesium and iron some of which contain chromium and nickel, such as Kaznakhtite. The locality is Kaznakhtinskiy ultrabasic massif which is metamorphosed to serpentinites.
The mineral was described by my friend Anatoly Kasatkin et al and published in the Mineralogical Magazine July 2022:
Kaznakhtite, Ni6Co3+2(CO3)(OH)16⋅4H2O, a new natural layered double hydroxide, the member of the hydrotalcite supergroup

It's hard to see in the photos, but the Kidwellite are the tiny yellow-green spheroidal crystal groups.
