It is hard to tell from the picture, but from the shade of blue it looks to be beryl. It could be azurite but from the photo the blue is to dark and borders purple. But you can see there is a slight layer of calcite carbonate in the seam. The lighter green looks to be a oxide of cooper or arsinic.
This is all best guesses. It is hard to tell from a photo on the internet unless it is really high res and high pixels.
