HEDENBERGITE SPECIMENS
Hedenbergite is a calcium iron (magnesium) silicate that often bears a range of green to brown colorations. The crystals are typically opaque and occur in stubby or prismatic aggregates. Inner Mongolia, Russia, and Greece all produce quartz crystals colored green as a result of fibrous hedenbergite inclusions. A variety of hedenbergite crystal forms can be found in Sweden as well; dark-green blocky crystals coming from the Nordmark Odal Field.
Hedenbergite was given its name in 1819 by Jöns Jakob Berzelius, a chemist in Sweden. He named the mineral in honor of Anders Ludvig Hedenberg, a chemistry student and co-worker of Berzelius. Hedenberg is credited with the first documented discovery and description of Hedenbergite in Tunaberg, Sweden.
