Sapphirine is a rare silicate, named for the blue color allusion and shape of sapphire. Sharp, moderately lustrous, indigo-blue sapphirine crystals to 1.2 cm are richly scattered on both sides of the quartz-rich pegmatite matrix and are nicely accented with pearlescent, honey-brown phlogopite books. This is a highly representative, larger and extremely rich example of the rare species in combination and locale.
