A 4.80-carat emerald cut from Namibia in a saturated blue-green with strong axial dichroism: the stone reads teal face-up and shifts toward forest green under different orientations. Namibian tourmaline from the Klein Spitzkoppe and Erongo regions is known for clarity and concentrated color. The emerald cut here is correct for this stone — its step facets impose order on the color and reward deliberate viewing. Clean and architectural.
