Purple-capped tourmalines are very rare and this particular polychrome elbaite features a thick, gemmy, purple cap! The lower, translucent watermelon portion transitions into an 8 mm, gemmy green layer that has hints of blue at the bottom of the zone and a distinct, 0.5 mm, green-blue band at the top which immediately transitions into the sexy, gemmy, 5 mm thick purple cap! The striated, trigonal prism faces are glassy and, unlike the other tourmaline crystals in this group, it has a truly high-luster pedion termination modified by lustrous pyramid faces that exhibit really neat and subtle growth hillocks! An amazing polychrome elbaite! Weight is 21 grams. Small but mighty - it glows, practically. My personal favorite of the lot.
