Hashemite is a rare pyrometamorphic rock formed by the combustion of organic matter in sedimentary rocks, often found in the Hatrurim Formation. It typically appears as a dense, dark, banded material that is highly prized by collectors for its unique geological origin and complex mineral composition.

Is this hashemite?

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 hashemite with a known reference. Hashemite sits at Mohs 5-6, softer than the next harder reference, harder than the previous one.
2
Check the streak
Drag the specimen across an unglazed porcelain plate. Hashemite leaves a white streak.
3
Read the luster
Hold the specimen under a strong light. Hashemite typically shows a submetallic luster.
4
Match the color range
Compare against the expected color range: dark brown, black, reddish-brown.
5
Look at form & habit
Typical habit: massive.

Field-hunting tip

Look in pyrometamorphic complexes country, the host setting where hashemite typically forms. If you start seeing gehlenite, wollastonite, anorthite in float, you are in the right ground. Field specimens usually show a massive habit, so train your eye for that shape before scanning the outcrop.
