Cherry blossom or Sakura Agate is a new discovery from Madagascar. 
It's a form of soft pink Agate/Chalcedony, and instead of a traditional 2-dimensional plume found in other types of similar agates, Flower Agate plumes are more 3-dimensional, and the cross-section creates a gorgeous flower-like plume, these are wonderful stones as they have a soft and gentle encouraging energy that nudges you to live to your fullest.
Said to be a stone of growth which reminds you to honor and appreciate each part of the process of evolving.
