Paratimroseite is a rare lead-selenium mineral typically found as small, tabular crystals in highly oxidized zones of mineral deposits. It is best identified through micro-analysis due to its similarity to other rare lead-selenite species often found in arid mining regions.
Is this paratimroseite?
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 paratimroseite with a known reference. Paratimroseite sits at Mohs 2-3 — softer than the next harder reference, harder than the previous one.
- 2Check the streakDrag the specimen across an unglazed porcelain plate. Paratimroseite leaves a pale yellow streak.
- 3Read the lusterHold the specimen under a strong light. Paratimroseite typically shows a adamantine luster.
- 4Match the color rangeCompare against the expected color range: yellow, yellowish-orange.
- 5Look at form & habitCrystal system: triclinic. Typical habit: tabular crystals.
Often confused with
Paratimroseite vs. its common look-alikes — and how to tell them apart in the field.
How to tell apart: Streak differs — Paratimroseite leaves pale yellow, Timroseite leaves light green.
How to tell apart: Streak differs — Paratimroseite leaves pale yellow, Molybdomenite leaves white; luster reads adamantine on Paratimroseite and pearly on Molybdomenite.

Field-hunting tip
Look in oxidized lead-selenium ore zones country — that is the host setting where paratimroseite typically forms. If you start seeing anglesite, cerussite, paralaurionite 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.
