Here is a gemmy, vibrant green tourmaline with a remarkable feature on the termination: sunken triangles! These are sometimes called "trigonic" crystals, and also sunken "record keeper" crystals. The sunken triangles are probably the result of crystal growing under determinate circumstances or just a consequence of etching . These are like triangle-shaped keyholes in the face of the crystal that appear to have been cut into the stone, receding into the surface of the crystal. This configuration is extremely rare.
