The photos show large-sized Gypsum Desert Rose also called Selenite Desert Rose and Sand Rose. They are an amazing natural creation. They are the larger ones in my hand. We also have smaller size (in my hand) as set of 4 can also be bought here too.
These selenite grow in sand so don’t put them in a watery area or they will dissolve. And the petals are delicate so minimal touch and feel. If you want to use them energetically, put them on cotton balls in a white box so you hold the box to carry. You can see a variety of different sizes at the shops.
Specifically this form is good to rid the mind of old thought-processes that we hold that are outdated or overused. It is an excellent stone for intuitive work.
We will intuit the right desert rose cluster for you are all very similar.
