Rubies from Montepuez, Mozambique
Author : GIA : GIA Field Gemology Project
In this video, you’ll explore Mozambique’s Montepuez ruby deposit with GIA’s dedicated field gemology team. First, you’ll see how the legal owner of the mining rights—Montepuez Ruby Mining (MRM), a subsidiary of the Gemfields corporation—works the area in steps from prospecting through separating the rubies from the ore, to sorting and eventual sale at their Singapore rough auction. In the second part you’ll also catch a glimpse of a day in the life of the thousands of unlicensed miners—garimpeiros—who conduct unauthorized mining in the MRM-owned area.
