CITRIN - Natural - NOT burnt !
The CITRINES from this deposit in Congo are very dark - appear optically like SMOKE QUARTZ but are YELLOW in transmitted light.
The crystals are not the TOP facetier quality, they lack brilliance, but are interesting for mineral collectors, as CITRINS from Central Africa are rather rare to see.
