This hand specimen of brochantite is rather appealing, because the crystals are in two sizes causing two colors which contrast. The host rock is limonite, upon which formed clusters of relatively large brochantite crystals. They are well formed, and a very dark green in color. Individually, the crystals are intensely green and transparent. Interspersed among these crystals is a mat of acicular brochantite crystals, and these appear much lighter in color to the unaided eye, giving the nice contrast I noted earlier. Under a loupe, all of the crystals are the same intense green, which is surprising given the different appearance to the naked eye.
