Jouravskite on Xonotlite

We were very fortunate to get an entire flat of this super rare material last year and have very few left. No telling if more will come out. This specimen has excellent coverage and top screaming yellow color. Just the right amount of white xonotlite to encircle the yellow. One of the few minerals that can boast membership in BOTH the sulfate and carbonate families!

Locality: N’Chwaning 3 Mine, KMF, Near Kuruman, South Africa
