Abhurite is a rare tin-oxychloride mineral that typically forms as a result of the corrosion of tin-bearing artifacts submerged in seawater. It usually presents as small, colorless to white platy or tabular crystals on the surface of the corroded metal.

Is this abhurite?

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 abhurite with a known reference. Abhurite sits at Mohs 2 — softer than the next harder reference, harder than the previous one.
2
Check the streak
Drag the specimen across an unglazed porcelain plate. Abhurite leaves a white streak.
3
Read the luster
Hold the specimen under a strong light. Abhurite typically shows a pearly luster.
4
Match the color range
Compare against the expected color range: colorless, white.
5
Look at form & habit
Crystal system: trigonal. Typical habit: tabular crystals, platy aggregates.

Often confused with

Abhurite vs. its common look-alikes — and how to tell them apart in the field.

mineral

Cassiterite

Mohs 6-7

How to tell apart: Cassiterite is the harder of the two (Mohs 6-7 vs. 2); luster reads pearly on Abhurite and adamantine on Cassiterite.

How to tell apart: Streak differs — Abhurite leaves white, Romarchite leaves black; luster reads pearly on Abhurite and submetallic on Romarchite.

Where rockhounds find abhurite

Classic worldwide localities

Red Sea coast, Saudi Arabia
Laurion, Greece

Field-hunting tip

Look in corroded tin-bearing artifacts in marine environments country — that is the host setting where abhurite typically forms. If you start seeing cassiterite, romarchite, anglesite in float, you are in the right ground. Field specimens usually show a tabular crystals, platy aggregates habit, so train your eye for that shape before scanning the outcrop.

Common questions

How do you identify abhurite?+

Mohs hardness is 2. It typically shows a pearly luster. The streak is white. Common colors include colorless, white.

Where is abhurite found?+

Notable localities include Red Sea coast, Saudi Arabia; Laurion, Greece.
