Is this olympite?

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 olympite with a known reference. Olympite 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. Olympite leaves a white streak.
  • 3
    Read the luster
    Hold the specimen under a strong light. Olympite typically shows a vitreous luster.
  • 4
    Match the color range
    Compare against the expected color range: white, colorless.
  • 5
    Look at form & habit
    Crystal system: trigonal. Typical habit: tabular crystals.

Where rockhounds find olympite

Classic worldwide localities

  • Tolbachik volcano, Kamchatka, Russia

Field-hunting tip

Look in fumarole deposits country — that is the host setting where olympite typically forms. If you start seeing tolbachikite, tenorite, sylvite in float, you are in the right ground. Field specimens usually show a tabular crystals habit, so train your eye for that shape before scanning the outcrop.
