A large loose pink floater octahedral crystal of spinel. In great condition all around. Intensely fluorescent red under longwave ultraviolet light.Mahenge, located in the Morogoro Region of Tanzania, has a history rooted in the slave trade era, a missionary post established around 1897, and small-scale gem mining that began attracting global attention following initial discoveries in the late 1980s and a massive neon-pink spinel find at Ipanko in August 2007 (while specific mining operations open and close periodically based on artisanal yields, commercial activity remains active with ongoing graphite and gemstone extraction). Geologically, the area is part of the Neoproterozoic Mozambique Belt, consisting primarily of high-grade metamorphic rocks such as schist, calc-silicate rocks, and dolomite-dominant marbles that host world-renowned gem deposits shaped by intense tectonic activity and high zinc-chromium availability.
