Rare Blood Iolite Sphere,74mm

Blood Iolite, commonly known as bloodshot iolite or iolite sunstone, is a fascinating variety of the mineral cordierite that features visible, dramatic reddish or coppery inclusions.

These inclusions are typically platelets of hematite or lepidocrocite, which float within a translucent violet-blue base. The contrast between the deep moody indigo and the tiny red flakes creates a shimmering effect known as aventurescence.
