Actinolite in Prehnite CRYSTAL 925 Silver Ring Size 7.5
 
I came upon a natural small piece of actinolite...I started pulling off it what I thought was a cobweb, but NO! Surprise Surprise it was the actonolite I was pulling apart, whoops!  Luckily this is encased in Prehnite.  This is how I discovered this stone, then went to buy myself one and thought best buy 2, 1 to share with YOU!
