The mineral typically does not have a distinct streak. Due to its rarity and specific chemical composition, it is often confused with other uranyl arsenates, but its color and hydration state can help in differentiation.
Trivia
Metakirchheimerite is a rare mineral with a complex chemical formula involving cobalt, uranium, and arsenic.
