Refikite is a rare organic mineraloid derived from the oxidation of fossil resins found in volcanic fumaroles. It typically appears as yellowish, resinous masses or crusts within sulfur-rich volcanic environments. Because of its organic nature and formation process, it is highly sought after by specialized mineral collectors.
Is this refikite?
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 refikite with a known reference. Refikite sits at Mohs 1-2 — softer than the next harder reference, harder than the previous one.
- 2Check the streakDrag the specimen across an unglazed porcelain plate. Refikite leaves a white streak.
- 3Read the lusterHold the specimen under a strong light. Refikite typically shows a resinous luster.
- 4Match the color rangeCompare against the expected color range: yellow, white, colorless.
- 5Look at form & habitCrystal system: orthorhombic. Typical habit: resinous masses.

Field-hunting tip
Look in fumarolic deposits in volcanic rocks country — that is the host setting where refikite typically forms. If you start seeing sulfur, gypsum in float, you are in the right ground. Field specimens usually show a resinous masses habit, so train your eye for that shape before scanning the outcrop.
