Tourmaline is a favorite among designers for its exceptional range of color and its strong pleochroism, meaning the stone can show different hues depending on the viewing angle - something worth considering when setting and orienting each stone. California tourmaline, particularly from the historic Himalaya Mine in San Diego County, has a well-documented collector following and a distinct character tied to that pegmatite deposit, which can add provenance interest to finished work. Tourmaline has no cleavage, which makes it relatively forgiving to work with, though the crystals can carry internal stress and care with heat application is advisable.
