Color zoned Elbaite crystals to 3cm on a terminated Quartz crystal. The main Tourmaline has unusual color zoning - whereas most Tourmaline will be zoned either perpendicular to the C-axis or along the C-axis (such as 'watermelon' Tourmaline), this crystal has a strange and irregular shaped area without any color (achroite), the other end having typical pink coloration. Fine and undamaged.
