Here are some Blue Aventurine tumbles in 2 larger than usual sizes. Bought a whole range of larger than normal tumbles so a nice hand hold without the expense of a palm stone. You will get one of these in the photo I will intuit which is energetically best for your needs. Dimensions are of one of the $9.50 stones.
Use this stone to create order in your life such as self-discipline, and orderliness. It is said to reduce pain and chronic stiffness. I have used it to lower the level of muscle twitches and spasms. More about it on the Healing tab.
Blue Aventurine Tumbles are also known as Blue Quartz tumbles.
