Green fluorite is prized by collectors for its vibrant, intense emerald to sea-foam green hues and high-quality cubic or octahedral crystal habits. It is frequently found in hydrothermal veins and sedimentary limestone deposits, often associated with other colorful metallic minerals.
Is this green fluorite?
5-step field checkRun through these checks against the specimen in your hand. The more boxes tick, the more confident the ID.
- 1Test the hardnessTry to scratch green fluorite with a known reference. Green Fluorite sits at Mohs 4 — softer than the next harder reference, harder than the previous one.
- 2Check the streakDrag the specimen across an unglazed porcelain plate. Green Fluorite leaves a white streak.
- 3Read the lusterHold the specimen under a strong light. Green Fluorite typically shows a vitreous luster.
- 4Match the color rangeCompare against the expected color range: green, light green, emerald green, blue-green.
- 5Look at form & habitCrystal system: isometric. Typical habit: cubic crystals, octahedral crystals, massive.

Field-hunting tip
Look in hydrothermal veins, limestone cavities, granite pegmatites country — that is the host setting where green fluorite typically forms. If you start seeing calcite, barite, galena in float, you are in the right ground. Field specimens usually show a cubic crystals, octahedral crystals, massive habit, so train your eye for that shape before scanning the outcrop. In the U.S., the densest reported localities are in Montana — start trip planning there.
