Was looking through the gravel earlier today and found this peculiar little stone. At first I thought it was a piece of glass worn out by the water streams to resemble a shape of pebble, but upon closer inspection I noticed that it's not the case. I had a friend identify it and lo and behold, turns out I found a sample of aquamarine https://en.wikipedia.org/wiki/Beryl.....ine_and_maxixe

Small, but valuable addition to my collection! :D
