Příbramite is a very rare copper antimony selenide mineral originally described from the famous silver mining district of Příbram, Czech Republic. It typically occurs as small, metallic grains associated with other selenides and sulfides in hydrothermal vein systems. Collectors value it for its extreme rarity and specific occurrence within historical mining locales.

Is this příbramite?

4-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 příbramite with a known reference. Příbramite sits at Mohs 3-4, softer than the next harder reference, harder than the previous one.
2
Read the luster
Hold the specimen under a strong light. Luster: metallic.
3
Match the color range
Compare against the expected color range: lead gray.
4
Look at form & habit
Crystal system: orthorhombic. Typical habit: massive, granular, or fine-grained aggregates.

Field-hunting tip

Where it forms: In a complex uranium and base-metal mining district. If you start seeing antimonselite, dzharkenite, ferroselite in float, you are in the right ground. Typical habit: massive, granular, or fine-grained aggregates. Train your eye for that shape before scanning the outcrop.
