Hello,

I live in Saudi Arabia and we went out in the desert to look for Sand Roses and I don't know much about them...
We found a fair few, but some of them are crumbling...do they last? How long? How can I keep them forever intact?
I seem to have read that they are made from Gypsum or Baryte and that the gypsum ones tend to be more fragile..I washed the sand off of them and so did my friend. I know because there is mineral in it and that these types of rocks might be "alive" and therefore transform with time, with weathering, light etc. But I want to keep my roses :/....can anyone help me?? Thanks in advance!
