Regional guide
Jeremejevite from Erongo Mountains, Namibia
from the Erongo Mountains is one of the defining rare-mineral stories of early-21st-century Namibia: a tiny run of pale to saturated blue aluminum borate crystals, many initially mistaken for aquamarine, that turned a mineralogical rarity into a coveted collector species. The best Erongo examples are slender, transparent to gemmy prisms with a cool blue core, glassy luster, sharp hexagonal outlines, and color zoning that may fade toward a near-colorless or pale termination. In hand, fine crystals have the delicacy of aquamarine but a different optical personality—more steely, more pleochroic, and often with a columnar, needle-like poise that makes even a thumbnail feel important.
