A tiny subordinate tourmaline cryspink, and the rest is nearly colourless (Figure into two components: the top quarter from the sample is pink, and also the rest is nearly colourless (Figure 2c,d). This smaller crystal also tourmaline tal is parallel intergrowth together with the prime physique crystal. A compact subordinate exhibits the crystalcolour zonation. The pink aspect tourmaline exhibits intense pleochroism from pink identical is parallel intergrowth with all the prime physique crystal.

The pink tourmaline shows negliable pleochroism. Pretty poor pink to light pink though the colourless aspect tourmaline shows negliable pleochroism. Incredibly poor cleavage and flawlessness u.
