A fine and aesthetic bicoloured, single twinned prismatic crystal of Orthoclase Feldspar measuring to 5.2 cm from Baveno in Piedmont, Italy. The bicoloured crystal varies from salmon to mainly white, with some greenish Chlorite on one long face. The twinning on this crystal is subtle yet perceivable, apparent from the tiny re-entrant angle on the termination, showing its Baveno Law twin habit.\n
