Kenhsuite is a rare mercury chloride-sulfide mineral found in oxidized zones of mercury deposits. It typically presents as small, canary yellow crystalline coatings or aggregates associated with other mercury halides and minerals like cinnabar.
Is this kenhsuite?
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 kenhsuite with a known reference. Kenhsuite sits at Mohs 2, softer than the next harder reference, harder than the previous one.
- 2Check the streakDrag the specimen across an unglazed porcelain plate. Kenhsuite leaves a canary yellow streak.
- 3Read the lusterHold the specimen under a strong light. Kenhsuite typically shows a vitreous luster.
- 4Match the color rangeCompare against the expected color range: canary yellow.
- 5Look at form & habitCrystal system: orthorhombic. Typical habit: microcrystalline aggregates, encrustations.
Often confused with
Kenhsuite vs. its common look-alikes, and how to tell them apart in the field.
How to tell apart: Streak differs, so Kenhsuite leaves canary yellow, Cinnabar leaves scarlet; luster reads vitreous on Kenhsuite and adamantine on Cinnabar.
How to tell apart: Streak differs, so Kenhsuite leaves canary yellow, Calomel leaves white; luster reads vitreous on Kenhsuite and adamantine on Calomel.
How to tell apart: Streak differs, so Kenhsuite leaves canary yellow, Terlinguaite leaves yellow; luster reads vitreous on Kenhsuite and adamantine on Terlinguaite.

Field-hunting tip
Look in mercury-bearing hydrothermal deposits country, the host setting where kenhsuite typically forms. If you start seeing cinnabar, calomel, eglestonite in float, you are in the right ground. Field specimens usually show a microcrystalline aggregates, encrustations habit, so train your eye for that shape before scanning the outcrop.
