These are a lovely pale blue Aquamarine Tumbles so energetically connects heart to throat making it easier to release, speak, think from the heart. These are a mid grade some very sparkly, some more opaque with green hints.
I have found myself recently really connecting to aquamarine for the first time as a means of releasing that which Spirit says needs to go now! You will get one of these in the photo I will intuit which is energetically best for your needs. How about gridding with them and buy a bag of 6?
This crystal assists you to be tolerant and less judgemental of other and of yourself. It invokes tolerance of others, gives support to those overwhelmed by responsibility.
Like all tumbles, dimensions are a guide rather than actual and for B group..
If you want to wear an aquamarine tumble buy a medium spiral.
