7.65 ct Brazilian Watermelon Tourmaline Slice

Collector's Note
A classic natural watermelon tourmaline slice displaying strong concentric zoning: a saturated pink center framed by a lighter transition and vivid green outer rim. Its thin profile and near-round crystal cross-section make the natural growth pattern especially easy to appreciate face-up.
