Glassy and gemmy aqua crystals, to 3.5 cm in length, exhibit a rich blue color. White feldspar is also the host for splendent, black crystals of schorl to 1.25 cm in length. One fully terminated aqua crystal exhibiting unusual extended growth, is undamaged and yet it looks like a wedge shaped piece is missing. All the aquas have gemmy terminations and appear to be pristine. Fascinating!
