The Spectrum of Watermelon Tourmaline

Photograph one polished thin watermelon-tourmaline mineral slice standing vertically in a small hidden slot on a matte graphite mineral base. Its natural deep green outer ring, pale transparent middle and raspberry center glow in transmitted light; preserve irregular crystal contours and authentic tiny inclusions. Macro frontal view, slice filling the center but not touching the frame, one narrow pale reflection along its edge. Background fades from soft gray at the bottom to black above. A precise gemological art photograph, luminous internal depth rather than a flat color disc, no faceted jewel setting, no text.
