Morozeviczite is a rare germanium-bearing sulfide mineral typically found in complex base metal deposits. It is most recognized for its occurrence in the Tsumeb Mine, where it appears as minor metallic grains associated with other germanium minerals.

Is this morozeviczite?

5-step field check

Run through these checks against the specimen in your hand. The more boxes tick, the more confident the ID.

  • 1
    Test the hardness
    Try to scratch morozeviczite with a known reference. Morozeviczite sits at Mohs 4 — softer than the next harder reference, harder than the previous one.
  • 2
    Check the streak
    Drag the specimen across an unglazed porcelain plate. Morozeviczite leaves a black streak.
  • 3
    Read the luster
    Hold the specimen under a strong light. Morozeviczite typically shows a metallic luster.
  • 4
    Match the color range
    Compare against the expected color range: black, iron-black.
  • 5
    Look at form & habit
    Crystal system: cubic. Typical habit: anhedral grains, massive.

Where rockhounds find morozeviczite

Classic worldwide localities

  • Tsumeb Mine (Namibia)

Field-hunting tip

Look in hydrothermal polymetallic ore deposits country — that is the host setting where morozeviczite typically forms. If you start seeing germanite, renierite, galena in float, you are in the right ground. Field specimens usually show a anhedral grains, massive habit, so train your eye for that shape before scanning the outcrop.

Common questions
