• Tourmaline - Madagascar, rind and center

    Tourmaline – Natural, Other, Yellow

    A spectacular slice from a large tourmaline shows a cranberry red rind, bright pink just inside, and a yellowish green center. Although this beautiful specimen most likely isn't destined for faceting, it helps illustrate areas of a gem that could be subject to stress.
